WE HAVE a lesson-worthy game from the U.S. Amateur East competition held last month in Morristown. In this game, Leonard Chipkin, of Garden City, N.Y., confronted Jonathan Chin, of Clinton.
The game is worth studying — if you are a Stonewall Attack player or defender — because some points need to be made with respect on to how to play that system from either side. It is also worth looking at because at the moment White and Black agreed to a draw, White had a winning king and pawn ending.
MOVE BY MOVE
U.S. Amateur East, Morristown, 2015
Chipkin, Leonard vs. Chin, Jonathan
1.d4 d5 2.e3 Nf6 3.Bd3 e6
First point of note: As Black, you don’t have to be in a hurry to box your bishop in with e6. A good waiting move is 3…Nbd7 to meet the possible Colle System with g6 and Bg7 or to play c5 if White tries anything else. It even helps with e5 if White plays passively. Other good “waiting” moves are: 3…c5; 3…Nc6; 3…Bg4.
4.Nd2 Bd6 5.c3
White is being cagey here, still faking the Colle, while intending f4. He gets nowhere with an immediate 5.e4 dxe4 6.Nxe4 Nxe4 7.Bxe4 0–0 8.Nf3 Nd7
Worth considering was: 5…e5 6.dxe5 Bxe5 7.Ngf3 Nc6
Finally, the Stonewall Attack appears. It’s a reverse Dutch Defense, Stonewall Varition. White can go with either Nf3 or Qf3. The former is better because you’re playing the Dutch a move up. The latter is speculative, as the queen advance should generally be better prepared. Still, it scares the heck out of a lot of defenders!
Black needs to consider 6…c5 here.
7.Qf3 Re8 8.Nh3 Nf8 9.0–0 c5!
Ah, good! You must meet brewing flank attacks with counterplay in the center.
If you’re going to play the aggressive version of the Stonewall, which usually involves g4, then you can’t waste time with king shuffles. Play 10.Nf2
Black needs to play cxd4 or at least Bd7. b6 is slow.
11.e4! dxe4 12.Nxe4 Nxe4 13.Bxe4 Rb8 14.dxc5 Bxc5 15.Be3!?
Not bad, but if you are planning a kingside attack, you don’t want to exchange pieces. Play b4, then develop the bishop.
15…Bxe3 16.Qxe3 Bb7
Because each side has been somewhat less than active, a level position has come about. However, White has one thing in his favor: those three pawns vs. two pawns on the queenside — the queenside pawn majority. Something to remember.
Get a free tempo with 17.Rad1
17…Qc7 18.Bxb7 Qxb7 19.Rad1 Red8 20.Rd4? Rd7?
Black misses his chance to win material with 20…Rxd4 21.Qxd4 Qa6
21.Rxd7 Nxd7 22.Rd1 Nf6 23.Qd4 Qd5 24.c4!
Excellent move! Dares Black to exchange queens and gets his pawn majority moving.
24…Qxd4 25.Rxd4 Kf8 26.Nd3 Rc8 27.Kg1 Ke7 28.Ne5 Rc7 29.b3 Nd7 30.Nd3
White should exchange here. The king and pawn ending gives good winning chances. The winning idea is to get the White king up to the 4th rank, mobilize the queenside pawns and play a patient waiting game as Black either moves back with his king and loses, or runs out of pawn moves. Once Black plays e5, White exchanges and isolates the recapturing pawn, at which time his creating an outside passed pawn draws the Black king over and the e-pawn falls along with the other kingside dominoes. It’s tight, and an error by White or alert play by Black may hold it for the defense, but the odds are not good. Here is just one example of a possible line: 30.Nxd7 Rxd7 31.Rxd7+ Kxd7 32.Kf2 Kd6 33.Ke3 Kc5 34.a3 b5 35.cxb5 Kxb5 36.Ke4 f6 37.Kd4 h5 38.g3 a6 39.h3 a5 40.Kc3 Kc5 41.b4+ axb4+ 42.axb4+ Kd5 43.Kd3 g6 (43…e5 44.fxe5) 44.Kc3 e5 45.fxe5 fxe5 46.g4 hxg4 47.hxg4 g5 48.Kd3
30…Nc5 31.Kf2 Nxd3+ 32.Rxd3 Rd7 33.Rxd7+ Kxd7 34.Ke3 Kd6 35.Kd4 f6 36.b4 h5 37.a3 a6 38.g3 g6 39.h3 Kc6 40.Ke4 Draw agreed.
Black escapes because White doesn’t know his king and pawn endings. The reasons were given above. Here’s another way it could have gone: 40.g4 Kd6 41.g5 Ke7 42.gxf6+ Kxf6 43.h4 Ke7 44.Ke5 Players have to learn their endings as well as their openings.
WHITE TO PLAY AND WIN
A great first move: Threaten mate! 1.Bc8 Rxc8 A great second move: Sacrifice a rook! 2.Ra8+ Kxa8 A great third move: Initiateing a series of triangulating checks! 3.Qxc8+ Rb8 4.Qc6+ Rb7 5.Qa4+ Qa6 [5…Kb8 6.Qe8+ Qd8 7.Qxd8#] 6.Qe8+ Rb8 7.Qc6+ Rb7 [7…Qb7 8.Qa4+ Qa6 9.Qxa6#] 8.Qc8+ Rb8 9.Qxa6#
The power of the queen move is ably demonstrated, yet it could not happen unless that pawn — seemingly minding its own business — is quietly nestled on b6
