Aug-10-03  morphynoman2: As many of Janowski's not very known games, this is a masterwork. A win in 64 moves, after a queen sacrifice in the 13th move. Very impressive.

  Calli: 13.Bg5? just loses material. Its not a Queen sac when you get two bishops and a rook for the Q.
Aug-16-03  ChessPraxis: It's an interesting study in how to consolidate and win when you have this kind of material imbalance.

  Calli: White is down after his 13.Bg5 blunder. Everybody seems to think this is a Janowski queen "sac". Its is white struggling with "material imbalance" , not black.

Secondly, Janowski's 23...f5? probably blows the win. White, however, fails to push the a-pawn. For instance, 29.a4 R4e6 30.a5 Bc5 31.Qc4 may actually win for white! I don't see why Wolf can't play 32.bxc5 either.

  Pawn and Two: Wolf had a very good position at his 12th move, and could have continued with advantage by playing: (.94) (20 ply) 12.Qb4 Rb8 13.Qa5 0-0 14.Nc3 Re8 15.Be3, or (.91) (20 ply) 12.Qb3 Rb8 13.Be3 Ba8 14.Qa3 Qc8 15.Nbd2.

Instead, he played the interesting, but very unsound 12.Bg5?? Bxg5 13.Nxe5.

I believe Wolf overlooked that 13...Nxe5! entirely refuted his idea. After 13...Nxe5!, White can win the Queen with check, but he paid too high a price.

  Pawn and Two: As this interesting game continued, it was Janowski's turn to err.

White's 15.Qf1 looks unusual, but computer analysis indicates it was best. After 15.Qe2 0-0, White's weakness on d2, makes the development of his pieces very difficult.

At move 21, Janowski's (-1.15) (21 ply) 21...Bg4 22.Nf3 Rd4 23.Re1 was strong, but better was: (-1.58) (21 ply) 21...Ne7 22.Nb3 Bb6 23.Qc4 Bg4 24.Re1 Nd5 25.Qxa6 Ne3+, or (-1.29) (21 ply) 21...Bf5 22.Rd1 Rd4 23.Qh5 Bxe4+. In this last variation, Black is clearly winning if: 21...Bf5 22.Rd1 Rd4 23.Qxa6? Rexe4 24.Qa5 Rd5! 25.Nxe4 Bxe4.

At move 23, Janowski gave away his entire advantage with 23...f5? 24.Qxa6 Bxf3+ 25.Kxf3 fxe4+ 26.Kg4. Correct was 23... Rdxe4 24.Qxe4 Rxe4 25.Rxe4, (-1.42) (21 ply) 25...Ne7 26.Ne5 Bf5 27.Ra4 Bc8 28.Nd3 Bb6, and Black has the advantage and can continue to play for the win.

At move 26, Janowski could have maintained an equal position with: (.00) (20 ply) 26...Re6 27.c3 h5+ 28.Kxh5 Rd5+ 29.Kg4 Ne7 30.Qa4 Rg6+ 31.Kh3 Rh6+ 32.Kg4 Rd2 33.Rxe4 Rg6+ 34.kh3 Rh6+.

Instead, he erred with: (.51) (20 ply) 26...e3? 27.c3 Rde4 28.Kf3, and now for the first time since move twelve, it is White who has the advantage!

  Pawn and Two: The position after 28.Kf3 was very interesting:

Fritz indicates White has an advantage, but a closer review of one long variation, indicates Black still had a saving move: 28...e2! 29.a4 Re3+ 30.Kg2 Bd6 31.Qxc6 Bxf4! 32.a5 Kf8 33.a6 Ne5 34.Qxe8+ Kxe8 35.a7 Nd3 36.a8Q+, and this final position is equal!

A fascinating variation, and one that would have made this game widely known had it been played.

Instead of the correct 28...e2!, Janowski played 28...Bb6??. Wolf now had a chance to win this game with: (2.25) (21 ply) 28...Bb6?? 29.a4! Kf8 30.a5 Ra4 31.b4 Ra2 32.Re2 Ra3 33.Qc4 Ba7 34.Qxc6 Ne7 35.Qxc7, (3.41) (24 ply) 35...Bb8 36.Qd7 Rxc3 37.Rxe3 Rc7 38.Qd3 Ba7 39.Re2 h6, (4.53) (20 ply) 40.b5 Bc5 41.b6 Rcc8, (6.19) (20 ply) 42.Qb5 Bg1 43.a6 Red8 44.b7 Rb8 45.Qe5 Ng8 46.Rc2 Nf6 47.Qxb8, and White is clearly winning.

A huge missed opportunity for Wolf, after several weak moves by Janowski.
