The "Compromised" Defence to the Evans Gambit.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | B to B 4 | 3. | B to B 4 |
| 4. | P to Q Kt 4 | 4. | B takes P |
| 5. | P to B 3 | 5. | B to R 4 |
By retiring the Bishop to R 4, instead of to B 4 as in the previous
variations, Black reserves the option of adopting either the
"Compromised" or the "Normal" Defence.
| 6. | P to Q 4 | 6. | P takes P |
| 7. | Castles | 7. | P takes P |
The capture of this, the third Pawn, constitutes the "Compromised"
Defence, so called because it was formerly considered that this capture
compromised Black's game.
| 8. | Q to Kt 3 | 8. | Q to B 3 |
| 9. | P to K 5 | 9. | Q to Kt 3 |
If 9. ... Kt takes P, White would win with 10. R to K sq., P to Q 3.
11. Kt takes Kt, P takes Kt. 12. Q to R 4, or Kt 5: ch., winning a
piece.
| 10. | Kt takes P | 10. | K Kt to K 2 |
| 11. | B to R 3 | 11. | Castles |
| 12. | Kt to Q 5 | 12. | Kt takes Kt |
| 13. | B takes Kt | | ... |
If White were to capture the Rook, the course of the game would
probably be as follows—
| 13. | B takes R | 13. | Kt to B 5 (!) |
| 14. | Kt to R 4 | 14. | Q to Kt 5 |
| 15. | Q to Kt 3 | 15. | P to Q 4 |
| 16. | Q takes Q | 16. | B takes Q |
And White must lose one of the two attacked Bishops.
| ... | 13. | P to Q 3 |
| 14. | P takes P | 14. | P takes P |
| 15. | Q R to Q sq. | 15. | R to Q sq. |
| 16. | Q to R 4 | | ... |
Threatening to win a piece with 17. B takes Kt.

| 19. | Q takes B P | 19. | R to Kt sq. |
| 20. | R takes P | 20. | B to K 3 |
The only defence, for Queen and Rook are attacked, and he cannot
play 20. ... R takes R, because of 21. Q to K 8 mate.
Threatening 22. R takes R: ch., R takes R: 23. R takes R: ch., B takes
R; 24. Q to K 8: mate.
The position being perfectly even, the game should result in a draw.
There is no danger now for Black to lose a piece, because after 22. R
takes R: ch., R takes R: 23. R takes R: ch., B takes R; 24. Q to K 8:
ch., K to R 2, White cannot play 25. Q takes B, because of 25. ... Q to
Kt 8: mate.
Second Variation.
Repeat the opening from preceding game up to
White's 9th move.
THE EVANS GAMBIT DECLINED.
From the foregoing illustrations of the Evans Gambit, it will be seen
that this opening is exceedingly complicated both for the attack and the
defence. It is safer for Black to decline accepting the gambit,
which is done by playing 4. ... B to Kt 3. The opening is
then reduced to a Giuoco Piano, White having (theoretically speaking)
compromised his pawns on the Queen's side by having advanced them
prematurely, which advance may prove a weakness in the ending.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | B to B 4 | 3. | B to B 4 |
| 4. | P to Q Kt 4 | 4. | B to Kt 3 |
| 5. | P to Q R 4 | | |
The best move. 5. P to Kt 5 is inferior, as shown exhaustively in the
following variations:—
| 5. | P to Kt 5 | 5. | Kt to R 4 |
| 6. | Kt takes P | 6. | Kt to R 3 (!) |
| 7. | P to Q 4 | 7. | P to Q 3 |
| 8. | B takes Kt | 8. | P takes B |
Not 8. ... P takes Kt, because of 9. B takes P, R to K Kt sq.; 10. B
takes P: ch., K takes B; 11. B takes P, Q to Kt 4; 12. P to Kt 3, B to Kt
5; 13. P to B 3, with four pawns for a piece, which is more than an
equivalent.
Not 9. B takes P: ch., because of 9. ... K to K 2; 10. Q to B 3, R to
B sq. (!); 11. Kt to Q B 3, B to K 3; 12. Q to B 5, B takes B (if 12. ...
B takes Q; 13. Kt to Q 5, mate), and wins; or 12. Q to R 5, then P takes
Kt, and wins.
| ... | 9. | Q to B 3 |
| 10. | Q to R 5 | | ... |
Not 10. Kt takes R, became of 10. ... B takes P; 11. Q to R 5: ch., K
to K 2; 12. Q to B 7: ch., Q takes Q; 13. B takes Q, B takes R, and wins.
Equally bad would be 10. P to K 5, P takes P; 11. Kt takes P, Kt takes B;
12. Kt takes Kt, B takes P, and wins.
| ... | 10. | Castles (quite legal) |
| 11. | Kt takes R P: dble. ch. | 11. | K to Kt 2 |
| 12. | Kt to Kt 4 | 12. | B takes Kt |
| 13. | Q takes B: ch. | 13. | K to R sq. |
| 14. | Q to K 2 | 14. | B takes P, and wins. |
Not 5. ... Kt takes P, which would be met by 6. P to R 5, with a
winning attack. And not 5. ... P to Q R 4, which is inferior to the text
move, and weakens the pawns on the Queen's side for the End game.
| 6. | Castles | 6. | P to Q 3 |
| 7. | P to B 3 | 7. | Kt to B 3 |
| 8. | P to Q 3 | | |
The position is now equivalent to the Giuoco Piano, except that White
has advanced his Queen's side pawns, which is a slight disadvantage.
THE TWO KNIGHTS' DEFENCE.
Reverting to the opening moves of the Giuoco Piano, in answer to 3. B
to B 4, Black may play (instead of 3. ... B to B 4), 3. ... Kt to B 3.
This constitutes the Two Knights' Defence. White may continue with
4. P to Q 3, or Kt to B 3, or adopt a more spirited line of play with 4.
Kt to Kt 5. Black's defences being 4. ... P to Q 4. or 4. ... Kt takes P.
We append one or two leading variations:
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | B to B 4 | 3. | Kt to B 3 |
| 4. | Kt to Kt 5 | | ... |
In the Giuoco Piano, where Black's Knight would be still at Kt sq.,
this advance would be bad, because Black could reply 4. ... Kt to R 3,
defending the K B P. Here, however, it is
the best move. Black's best defence is
| ... | 4. | P to Q 4 |
| 5. | P takes P | 5. | Kt. takes P (?) |
Not to be recommended. The best move is 5. ... Kt to Q R 4.
| 6. | Kt takes B P (!) | 6. | K takes Kt |
| 7. | Q to B 3: ch. | 7. | K to K 3 |
In order to defend the Knight, which is twice attacked. 7. ... Q to B
3 would be bad policy, for in such case White would play 8. B takes Kt:
ch., B to K 3; 9. B takes Kt, P takes B; 10. Q takes P, with three Pawns
ahead.
White attacking the Knight once more, and Black defending it
again.
And we have the position depicted in Fig. 10. Black could not play 9.
... P takes P, for fear of 10. Q to K 4: ch., winning back the piece.
Pinning the Knight, so as to take off one of the defences of the Kt at
Q 4.
| ... | 10. | K to Q 2 |
| 11. | P takes P | 11. | K to K sq. |
| 12. | Castles Q R | 12. | B to K 3 |
| 13. | Kt takes Kt | 13. | B takes Kt |
| 14. | R takes B | 14. | P takes R |
| 15. | B to Kt 5: ch. | 15. | Kt to B 3 |
| 16. | B takes Q | 16. | R takes B |
| 17. | P to K 6, and wins. | | |
Second Variation.
Repeat as far as White's 8th move inclusive.
Should Black play, instead of 8. ... Kt to K 2, 8. ... Kt to Kt 5, the
following variations may ensue:
| 9. | Q to K 4 | 9. | P to Q Kt 4 |
| 10. | B to Kt 3 | 10. | P to B 4 |
| 11. | Kt takes P | 11. | B to R 3 |
| 12. | P to Q R 4 | 12. | R to B sq. |
| 13. | P to Q 3 | 13. | B to K 2 |
| 14. | Castles | | ... |
White threatens now a formidable attack with 15. P to K B 4, to be
followed by attacking the Knight with the Q B P, and so to win back the
piece.
| ... | 14. | B to Kt 2 |
| 15. | P to Q B 3 | 15. | P to Q R 3 |
If 15. ... Kt to R 3, White would win with 16. P to K B 4.
| 16. | Q to Kt 4: ch. | 16. | K to B 2 |
| 17. | P to K B 4 | 17. | R to B sq. (best) |
| 18. | P takes P: dis. ch. | 18. | K to Kt sq. |
| 19. | B to R 6 (!) | 19. | R takes R: ch. |
| 20. | R takes R | 20. | B to B sq. |
| 21. | Kt to Q 6, and wins. | | |
For the immediate threat, 22. Q to K 6: ch., or Kt takes B, is
fatal.
Third Variation.
Repeat the Opening up to Black's 5th move.
| 5. | |
| 6. | |

White has the better pawn
position on the Queen's side.
|
THE RUY LOPEZ.
This Opening, invented by the Spaniard Ruy Lopez in the sixteenth
century, is still resorted to in tournaments and matches, where caution
and safety are essential. Instead of developing the Bishop to Q B 4 with
the intention of an attack upon Black's weakest point—viz., the K B
P, White plays 3. B to Q Kt 5, threatening 4. B takes Kt, and 5. Kt takes
P. In answer to 3. B to Kt 5, Black may play 3. ... P to Q R 3; 3. ... K
Kt to B 3 (best); 3. ... K Kt to K 2 (not so good); 3. ... B to B 4; 3.
... Kt to Q 5 (not to be recommended); 3. ... P to Q 3 (a safe, but dull
defence); 3. ... P to B 4 (risky); and 3. ... P to K Kt 3, the latter
involving the development of the K B to Kt 2.
White's replies are, in answer to 3. ... P to Q R 3; 4. B takes Kt; or
4. B to R 4. And in answer to 3. ... Kt to B 3; 4. Kt to B 3; 4. P to Q
3; 4. Q to K 2; 4. P to Q 4, or 4. Castles.
The main defences are 3. ... P to Q R 3, and 3. ... Kt to B 3. The
latter is to be preferred; for to a certain extent the White Bishop is
not in such a favourable position at Kt 5 as at R 4; it should,
therefore, not be driven into a better one.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | B to Kt 5 | | |
These moves complete the Ruy Lopez Opening.
| ... | 3. | P to Q R 3 |
| 4. | B to R 4 | | ... |
White could here temporarily win a pawn with 4. B takes Kt, Q P takes
B, 5. Kt takes P. But 5. ... Q to Q 5 wins it back for Black; it is,
therefore, useless to exchange the powerful King's Bishop.
| ... | 4. | Kt to B 3 |
| 5. | P to Q 3 | 5. | P to Q 3 |
This is the quietest form of the Lopez and may be adopted with
safety.
| 6. | Kt to B 3 | 6. | B to Q 2 |
| 7. | Castles | 7. | B to K 2 |
| 8. | P to Q 4 | 8. | P to Q Kt 4 |
| 9. | P takes P | 9. | Q Kt takes P |
| 10. | Kt takes Kt | 10. | P takes Kt |
| 11. | B to Kt 3 | 11. | Castles |
| 12. | B to Kt 5 | 12. | P to Q R 4 |
A good move, as it anticipates White's advance of the Q R P, and thus
renders the Queen's side safe.
| 13. | B takes Kt | 13. | B takes B |
| 14. | P to Q R 4 | 14. | P to Kt 5 |
It would be bad to play here 14. ... P takes P, because it not only
would give White an open Rook's file, but also isolate Black's R P
and Q B P, a weakness from which he could not recover against the best
play.
Neither side has so far gained any material advantage.
Second Variation.
Repeat the first five moves on either side.
Third Variation.
Repeat first four moves on either side.
Fourth Variation.
Repeat first four moves as above.
| 5. | |
| 6. | |
| 7. | | Kt takes P | | Kt takes Kt[91] |
|
| 8. | |
| |
Not 11. ... B to Kt 2, because of 12. B takes P ch., Kt takes B; 13. Q
takes B, &c.
About an even game.
At the present day, however, as we have said, the defence of 3. ... P
to Q R 3 is discarded by the best authorities in favour of 3. ... Kt to K
B 3. The game may then proceed as follows:
| 4. | Castles | 4. | Kt takes P |
| 5. | P to Q 4 | 5. | B to K 2 |
| 6. | Q to K 2 | 6. | Kt to Q 3 (!) |
| 7. | B takes Kt | 7. | Kt P takes B (!) |
If 7. ... Q P takes B, White would obtain an advantage by 8. P takes
P, Kt to B 4; 9. R to Q sq., B to Q 2; 10. P to K 6 (!), P takes P; 11.
Kt to K 5, Kt to Q 3 (or B to Q 3); 12. Q to R 5; ch., P to Kt 3; 13. Kt
takes Kt P, and wins.
| 8. | P takes P | 8. | Kt to Kt 2 (!) |
| 9. | Kt to B 3 | 9. | Kt to B 4 |
| 10. | Kt to Q 4 | 10. | Castles |
The tempting move 10. ... B to R 3, winning the exchange, would be
unsound, because of White's reply 11. Q to Kt 4, Castles; 12. B to R 6,
&c.
Another variation proceeds as follows:
| 4. | P to Q 4 | 4. | P takes P |
| 5. | Castles | 5. | B to K 2 |
| 6. | P to K 5 | 6. | Kt to K 5 |
| 7. | R to K sq. | 7. | Kt to B 4 |
| 8. | B takes Kt | 8. | Q P takes B (!) |
| 9. | Kt takes P | 9. | Castles |
| 10. | B to K 3 | 10. | R to K sq. |
| 11. | Kt to Q B 3 | 11. | Kt to K 3 |
| 12. | Kt to B 5 | 12. | Kt to B sq. |
| Even game. |
The remaining Openings, though not less important, we shall be
compelled to deal with more briefly. It must, however, be remembered that
it is only the first three or four moves on either side (or even less)
which constitute a given Opening. All beyond these are optional, though
in many instances the best moves in continuation on either side have been
ascertained by careful analysis, and these are consequently known, among
players, as "book" moves.
PHILIDOR'S DEFENCE.
After 1. P to K 4, P to K 4; 2. Kt to K B 3, Black may defend the
attacked King's pawn with 2.... P to Q 3, and this constitutes
Philidor's Defence.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | P to Q 3 |
| 3. | P to Q 4 | 3. | P takes P |
| 4. | Kt takes P | | ... |
If 4. Q takes P, Black replies 4.... Kt to Q B 3 (best); 5. B to Q Kt
5, B to Q 2; 6. B takes Kt, B takes B; 7. B to Kt 5, Kt to B 3; 8. B
takes Kt. Q takes B; 9. Q takes Q, P takes Q; 10. Kt
to B 3, and Black has two Bishops against two Knights, and an open Kt and
K file for his Rooks, and consequently the advantage.
| ... | 4. | Kt to K B 3 |
| 5. | B to Q B 4 | 5. | B to K 2 |

THREE KNIGHTS' GAME.
The Three Knights' Game is brought about if, after 1. P to K 4,
P to K 4; 2. Kt to K B 3, Kt to Q B 3, White plays 3. Kt to B 3, The
following is an example:
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | Kt to B 3 | 3. | B to Kt 5 |
| 4. | B to Kt 5 | 4. | K Kt to K 2 |
| 5. | P to Q 4 | 5. | P takes P |
| 6. | Kt takes P | 6. | Castles |
Even game.
FOUR KNIGHTS' GAME.
If Black moves 3. ... Kt to B 3, the previous moves being the same as
in the Three Knights' Game, it is called the Four Knights' Game.
It is convertible into a Ruy Lopez, if White plays 4. B to Kt 5; and into
a Double Ruy Lopez, if Black replies 4. ... B to Kt 5.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to Q B 3 | 2. | Kt to K B 3 |
| 3. | Kt to B 3 | 3. | Kt to B 3 |
| 4. | B to Kt 5 | 4. | B to Kt 5 |
| 5. | Castles | 5. | Castles |
| 6. | Kt to Q 5 | 6. | Kt takes Kt |
| 7. | P takes Kt | 7. | P to K 5 |
| 8. | P takes Kt | 8. | P takes Kt |
| 9. | Q takes P | | |
If White had played 9. P takes Q P, Black's best reply would have been
9. ... P takes P, attacking the Rook; if 9. P takes Kt P, Black replies
9. ... B takes Kt P, with a promising attack.
| ... | 9. | Q P takes P |
| 10. | B to K 2 | 10. | B to Q 3 |
Even game.
THE VIENNA OPENING.
If, after 1. P to K 4, P to K 4, White plays 2. Kt to Q B 3, the
Vienna Opening is the result. The Q Kt does not act immediately,
but rather seems to relinquish the advantage of the first move; but this
is only apparently so. For in all Openings the Q Kt plays an important
rôle, and, having this piece in play, White soon resumes the attack, and
with increased vigour in certain variations.
The defences for Black are—2. ... B to B 4; 2. ... B to Kt 5; 2.
... Kt to Q B 3; 2. ... Kt to K B 3. The latter yields the most
satisfactory results. 2. ... Kt to Q B 3 may lead to the Steinitz Gambit,
a difficult game for both sides; whilst 2. ... B to Kt 5 is the least
satisfactory variation of all.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to Q B 3 | 2. | Kt to K B 3 |
| 3. | P to B 4 | 3. | P to Q 4 (best) |
In this variation it is not advisable to take the offered Gambit pawn,
though Black might have done so if he had played 2. ... Kt to Q B 3
instead of 2. ... Kt to K B 3.
| 4. | B P takes P | 4. | Kt takes P |
| 5. | Q to B 3 | 5. | Kt to Q B 3 |
| 6. | B to Kt 5 | | ... |
If 6. Kt takes Kt, Black would win with 6. ... Kt to Q 5; 7. Q to Q 3
(best), P takes Kt; 8. Q takes P, B to K B 4, to be followed by Kt takes
P: ch. &c.
| ... | 6. | Kt takes Kt |
| 7. | Kt P takes Kt (!) | 7. | B to K 2 |
| 8. | P to Q 4 | 8. | B to K 3 |
| 9. | Kt to K 2 | 9. | Castles |
| 10. | Castles | | |
| With a very good game. |
| Second Variation.Even game. | Third Variation.Even game. |
THE STEINITZ GAMBIT.
This gambit is an offshoot of the Vienna Opening. It leads to a very
difficult game, and the student will be well advised to avoid it. It is,
however, desirable that he should know the moves of the Opening.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to Q B 3 | 2. | Kt to Q B 3 |
| 3. | P to B 4 | 3. | P takes P |
| 4. | P to Q 4 | | ... |
This constitutes the Steinitz Gambit. The White King becomes exposed
to a violent attack; but if the attack fails, White is able to exchange
pieces, and so obtain a superior End game, his King (an essential factor
in the ending) being in better play than the Black King.
THE SCOTCH GAME AND SCOTCH GAMBIT.
Next in importance to the Ruy Lopez and the Vienna Opening is the
Scotch, an Opening very frequently adopted in matches and
tournaments. If after 1. P to K 4, P to K 4; 2. Kt to K B 3, Kt to Q B 3;
White plays 3. P to Q 4, it is called the Scotch Game. Black's
best move is 3. ... P takes P (not 3. ... Kt takes P), and White can
either retake the Pawn or leave it. In the latter case the Opening
becomes the Scotch Gambit. The former Opening is considered
sounder than the latter, and for that reason is met with more frequently
nowadays. Formerly, when Gambits generally were more in vogue, the Scotch
Gambit enjoyed corresponding popularity. A few of the most essential
variations of this interesting Opening follow. First, of the Scotch
game.
| WHITE. | | BLACK. |
| 1. | P to K 4 | 1. | P to K 4 |
| 2. | Kt to K B 3 | 2. | Kt to Q B 3 |
| 3. | P to Q 4 | 3. | P takes P |
| 4. | Kt takes P | 4. | Kt to B 3 |
| 5. | Kt to Q B 3 | 5. | B to Kt 5 |
| 6. | Kt takes Kt | 6. | Kt P takes Kt |
