Logical Chess by Irving Chernev (available as PGN)??? - 2006/12/17 19:46
I have bought the book "Logical Chess - Move by Move" by Irving
Chernev, which explains the moves in 33 different games. Does anyone have these games in PGN format - preferably with the annotations, but without will do?
I found game #3 (see below) at
http://www.logicalchess.com/resources/lc/logical01parent.html (quite why its called game #1, when its 3 in the book I don't know), but I'd like to find the others if possible, without searching through the multi-million files. Obviously the annotations would be nice, but without will be okay, as I have the book.
[Event "Gand-Terneuzen"] [Site "Huntsville"] [Date "1929.??.??"] [Round "?"] [White "Colle"] [Black "Delvaux"] [Result "1-0"] [ECO "D05"] [PlyCount "43"]
1.d4 {D05: Colle System with ...e6. (Modern players consider this to be the strongest opening move. It is equal in value to 1. e4 in that two pieces are freed to action, while a Pawn seizes a center square.
Queen Pawn, though, stands protected in the center whereas the Pawn would be vulnerable to an early attack.)}
1...d5 {This move or 1... Nf6 is practically compulsory. White must not be allowed to play e4 and dominate the vital center squares with his Pawns.}
2.Nf3 {So great an authority as Lasker, World's Champion for twenty-seven years, says of this move, "In my practice I have usually found it strongest to post the Knights at c3 and f3, where they have a magnificent sway."}
2...Nf6 {Black follows suit in trumps, developing his King Knight to is most useful square.}
3.e3 {Generally, it is dubious strategy to release one Bishop while shutting in the other. In this game, White is adopting a system which calls for a storing up of dynamic energy behind the lines, which is released at the right time by an explosion at the key square e4.
this end, White develops so that his pieces exert their maximum pressure at e4. His Bishop will therefore occupy d3, and his Queen Knight d2. If more is needed, this Queen will supply it by developing at e2, or his King Rook by moving to e1. Then with all this potential energy ready to let loose, the King Pawn advances to e4, to rip the position apart and open fire on the King side. Development in the Colle system is on positional lines, but the objective is a
King-side attack!}
3...e6 {This deserves censure because it is a routine developing move which seems to take no thought of crossing White's plans. Clearly, it was better strategy either to attack White's Pawn center by 3... c5 or to counter by 3... Bf5. Not only is this latter a simple, sound developing move, but it prepares to oppose White's Bishop, which is headed for d3, with an equal force. The exchange of Bishops, which follows sooner or later, will deprive White of a most valuable weapon in King-side attacks.}
4.Bd3 {Notice the difference! White's Bishop commands a beautiful (and undisputed) diagonal, while Black's Bishop, covering squares of the same color, is hemmed in by the King Pawn.}
4...c5 {Very good! Black strikes at the Pawn formation in the center and gives his Queen access to the Queen side. This freeing move of the Bishop's Pawn is of the greatest importance in the Queen Pawn Openings.}
5.c3 {"Move only one or two Pawns in the opening!" say all the authorities, but no principle must be followed uncompromisingly. In the event of a Pawn exchange, White can recapture with the Bishop Pawn and maintain a Pawn at d4. Why not with the King Pawn? The King Pawn's future has previously been determined. It must stay on e3 and be ready to push on to e4 when the right moment comes, to spearhead a King-side attack.}
5...Nc6 {Another good move. The Knight comes into play toward the center, increasing the pressure on the Queen Pawn.}
6.Nbd2 {A queer-looking sortie. Not only does the Knight block the paths of the Queen and a Bishop but the piece itself seems to be doing little good. Yet, an expert would make this move without a moment's hesitation! For one thing, the Knight adds it weight to the pressure on the strategic square e4, the spring-board of the coming attack.
another, it is mobilized once it gets off the back rank. Finally, it can hop out of the way of the Queen and the Bishop when it is expedient for it to do so.}
6...Be7 {Black brings another piece into play (remember that the Bishop is doing a job once it leaves the last rank) and prepares to get his into safety by castling.}
7.O-O {The King flees to a less exposed sector, while the Rook comes out of hiding.}
7...c4 {This is the sort of move instinctively made by a beginner. Its purpose is to chase off an annoying piece from its favorable post.
move is weak because it releases the pressure on White's center. Tension must be maintained if Black is to have something to say about affairs in the vital area. Counter play in the center is the best means of opposing a King-side attack. And to secure counter play, the Pawn position must be kept fluid.}
8.Bc2 {Naturally the Bishop retreats, but stays on the diagonal leading to the e4 square, where the break will come.}
8...b5 {Primarily to make room at b7 for his Queen Bishop, but also with an eye to making trouble with an advance of his Queen-side Pawns.}
9.e4 {The key move in this opening! It will open up lines for an attack by White's pent-up pieces.}
9...dxe4 {Not an attractive choice for Black, but he cannot have the threat of e5 (displacing his Knight and severely cramping his movements) perpetually hanging over his head.}
10.Nxe4 {With this recapture, White's pieces that were crouched in the background spring onto the field. White has the initiative and a commanding position in which to exercise it. If no immediate attacking opportunities present themselves, he can quietly put on more pressure by Qe2, Rfe1, Bf4, (or Bg5) and Rad1, and wait for Black's game to crack.}
10...O-O {It might have been wiser to postpone castling (which ordinarily is highly recommended) as White is poised for an attack in that direction. This is another case where the value of a precept is conditioned by circumstances. Black would do better to try for counter play by 10... Qc7, followed by 11... Bb7 and 12... Rd8.}
11.Qe2 {A developing move which contains a threat of winning a piece. The idea is 12. Nxf6+ Bxf6 13. Qe4, and the threat of mate on the King side wins the exposed Knight on the Queen side.}
11...Bb7 {Black guards his Knight while developing another piece.}
12.Nfg5 $1 {Threatens 13. Nxf6+ Bxf6 14. Nxh7, and White has won a Pawn. Why an exclamation mark for a one-move threat to win a miserable Pawn?
glorify this move when Black cannot only save the Pawn but also cause White to lose time? Black simply moves the Pawn one square, rescues the Pawn, and forces White's Knight to retreat. The answer to the first question is that the advantage of an extra Pawn is enough to win, everything else being equal. Winning a Pawn at the cost of ruining one's position is of course meaningless. The answer to the second question is that White's purpose with his brilliant Knight move is to compel one of the Pawns defending the King to step forward.
secret of conducting a King-side attack successfully is to create a breach in the cordon of Pawns surrounding the King; to induce or force one of the Pawns to move. The change in the lineup of Pawns fixes the defense with a permanent weakness.}
12...h6 {"Touch the Pawns before your King with only infinite delicacy," says Santasiere. But, alas, it's too late! Black must disturb the Pawn position. Had he tried 12... Nxe4, the recapture by 13. Qxe4 threatens mate, and compels 13... g6 --and the Pawns are disarranged!}
13.Nxf6+ {Destroys the King Knight, the best defender of a castled position.}
13...Bxf6 {The alternative 13... gxf6 loses quickly. White could win either by gobbling up Pawns with 14. Nxe6 fxe6 15. Qg4+ Kh8 (15... Kf7 16.
mate) 16. Qg6 f5 17. Qxh6+ Kg8 18. Qxe6+, and the Bishop Pawn falls next, or with 14. Nh3 (threatening 15. Bxh6) Kg7 15. Qg4+ Kh8 16.
Rg8 17. Qh5 and the discovered check will be fatal.}
14.Qe4 {Threatens instant mate.}
14...g6 {Making room for the King's escape by 14... Re8 does not look inviting, as after 15. Qh7+ Kf8 16. Ne4, White's attack looks dangerous. It is preferable, though, to Black's actual move, which prevents the Queen's coming any closer, but alters the Pawn configuration. This change in the arrangement saddles Black with a weakness that is organic, one that can turn out to be fatal. All this is encouraging to White, but how does he proceed? How does he exploit the weaknesses in Black's position? And above all, what does he do about his Knight which is still under attack? Shall it retreat shamefacedly? Before moving the Knight back to f3 mechanically and unthinkingly, White looks carefully at the situation. The opportunity to strike a decisive blow may be here at this very moment, but one hasty "obvious move" may give his opponent just enough breathing time to reorganize his defenses. This is the position, and here is how White reasons out his attack. The key point must be Black's pawn on g6, which guards his King from invasion. If anything happens to this Pawn -- if it is captured -- the defense crumbles, and I can break into the fortress. How do I go about removing it from the board?
g6 Pawn is protected by the f7 Pawn. Suppose I destroy its support by sacrificing my Knight for the f7 Pawn? After 15. Nxf7 Kxf7 (or
15...
Rxf7) 16. Qxg6+, and I have two Pawns for my Knight, with a third one in sight, as the Rook Pawn must fall. Material is then approximately even, but his position is completely broken up, and clinching the win should be easy. This might be the general plan, but before putting it in motion, White analyzes the combination for possible flaws and comes up with this: If 15. Nxf7 Rxf7 (bringing another piece to the defense)
16. Qxg6+ Rg7 17. Qxh6 Nxd4!, and suddenly Black is the aggressor!
threatens mate in two by 18... Ne2+ 19. Kh1 Bxg2 mate, as well as outright ruin by 18... Rxg2+, followed by a deadly discovered check.
Clearly this line of play is too dangerous. Is there another way to break through, without letting Black's Rook come into the game?
Can I get rid of the f7 Pawn without disturbing the Rook? It is important that I remove this Pawn, as it supports the g6 and e6 Pawns. Wait a minute! There is a clue in the last sentence. The f7 Pawn, guarding two other Pawns, is serving two masters. Obviously it is overworked! I must add to its burden by luring it away from its present important post! Therefore:}
15.Nxe6 {The Knight captures a Pawn and attacks Queen and Rook.}
15...fxe6 {Black must accept the sacrifice or lose Rook and Pawn for the
Knight.
}
16.Qxg6+ {Stronger than taking the e6 Pawn, after which Black has four ways to get out of check. Each of these replies might lose, but it is more practical to attack the enemy with blows that leave him little choice of reply.}
16...Bg7 {The only move, as 16... Kh8 walks right into the mate.}
17.Qh7+ {White has other attractive continuations in 17. Bxh6 or 17.
Qxe6+, but this forces the King out into the open where White's other pieces can get at him.}
17...Kf7 {The only move.}
18.Bg6+ {Stronger than 18. Bxh6, to which Black retorts 18... Qf6, followed by 19... Rh8. The text move keeps him on the run.}
18...Kf6 {Certainly not 18... Ke7 when Qxg7+ lets White pick up a couple of Bishops.}
19.Bh5 {White is still angling for 20. Qg6+ Ke7 21. Qxg7+, and both come off the board.}
19...Ne7 {The only way to prevent the Queen's check.}
20.Bxh6 {White is not playing to pick up stray Pawns, but the capture brings another piece to the attack. The Pawn that is added to the collection is incidental to the general scheme of things.}
20...Rg8 {To parry the threat of 21. Qxg7+ Kf5 22. Qe5 mate. On 20... Bxh6 White intended 21. Qxh6+ Kf5 22. Rae1, and the threat of mate either by the Rook or the Knight Pawn is decisive.}
21.h4 {New threat: 22. Bg5 mate.}
21...Bxh6 {Loses on the spot, but there was no defense: if 21... e5 22.
Bxg7+ Rxg7 23. dxe5+, and the King must abandon the Rook.}
22.Qf7# {mate}
1-0.
