<34.g5> hxg5 35.f6 Rc7 36.Qg1 a4 37.Qg4 Qb6 38.h4 b3 39.cxb3 cxb3 40.a3 Rc2 41.f7+ Rxf7 42.Rxf7 Kxf7 43.Qh5+ g6 44.Qh7+ =

Fritz preferred: 34.f6 Rc7 35.g5 hxg5 36.Qg1 (.24) (21 ply), but after 36...c3 37.Qg4 cxb2 38.Rd2 a4 39.Qxe6+ Rff7 40.Qxd5 Qxd5 41.Rxd5 gxf6 42.exf6 a3 43.Rxg5+ Kf8 44.Rf1, Fritz indicated this position was also equal.

Fritz found some improvements in the first variation you provided: 34.g5 hxg5 35.f6 Rc7 36.Qg1 a4? (36...c3 leads to an equal position - see above) 37.Qg4 Qb6 38.h4 b3 39.cxb3 cxb3? (39...axb3 is better with a near equal position) 40.a3?, leading to an equal position.

Fritz showed that White had a much stronger continuation with 40.hxg5!: (1.19) (20 ply) 40.hxg5! bxa2+ 41.Kxa2 Rb8 42.Rd2 Rc1 43.f7+ Kf8 44.Qxa4.

At move 36, Fritz indicated the position was still equal. Schlechter should have continued with 36.f6 and equality, instead of playing 36.Rxd4?.

In your second variation: 36.f6 Qxe5 37.g5 a3 38.fxg7 Rxf4 39.Rxf4 Kg8 41.Rf6+ Kg7 42.cxb3, the position was equal after: (.00) (21 ply) 42...Qe4+ 43.Ka1 Qh1+ 44.Qf1; or (.00) (21 ply) 42...c3 43.bxc3 Qe4+ 44.Ka1 Qh1+ 45.Qf1; or (.00) (21 ply) 42...cxb3 43.Rf4 bxa2+ 44.Kxa2.

After 36.Rxd4? Qxe5, Black obtained the edge. However, White still had some drawing chances by playing 37.a3: (-.38) (21 ply) 37.a3 b3 38.Kc1 exf5 39.gxf5.

After 37.Rff4?, White was clearly lost. 38.c3 was not his best continuation, but even after: (-1.57) (20 ply) 38.Kc1 a3 39.bxa3 bxa3 40.h5 Rb8 41.Rfe4 Qb5 42.Rxc4 Qb2+ 43.Kd2 Qxa2, Black has a winning position.

In this game, Schlechter obtained an advantage in the opening. After 15.Kb1, Fritz indicated the best line was: (.56) (20 ply) 15...Rae8 16.g4 e5 17.fxe5 Rxe5 18.Nf5.

However, after 15.Kb1, Halprin erred with 15...c5?. Schlechter then had a considerable advantage. Fritz preferred the following continuations: (1.30) (22 ply) 17.Nc3 Nb6 18.f5, or (1.35) (22 ply) 17.e5 dxe5 18.Bxf6, or (1.37) (22 ply) 17.g4 a6 18.Nc3. Additional analysis would be needed to determine if any of these lines lead to a definite win for White.

Schlechter's continuation of 17.Nc4, was also very strong, and may have actually been White's best continuation.

After 17.Nc4 d5 18.Ne5 Qe8 19.Nxd7 Qxd7, Schlechter should have continued with 20.g4!: (1.33) (21 ply) 20.g4 a6 21.Nc3 d4 22.g5 Ne8 23.e5 hxg5 24.Bxg5, (1.97) (20 ply) 24...Rf5 25.Ne4 Ba7 26.Ng3 Rf7 27.f5 Nc7 28.f6 Nd5 29.Qh5, and White has a winning position.

Instead of 20.g4!, Schlechter played 20.Bxf6?, giving up a considerable amount of his advantage.

After 20.Bxf6? Rxf6, instead of (.50) (20 ply) 21.e5? Rf5, the best continuation was: (.81) (20 ply) 21.Nc3! Rxf4 22.Rxf4 Bxf4 23.g3 Bd6 24.exd5 exd5 25.Rxd5, and White has a strong position.

Schlechter then got one more winning opportunity. Halprin failed to defend correctly after 21.e5 Rf8 22.Nc3. He incorrectly played 22...a6?, better was 22...Qe8, 22...Qc6, or 22...Qc7.

As noted in the tournament book, Schlechter should then play 23.f5!. This move would have given White strong winning chances: (1.24) (21 ply) 23.f5! Bc7 24.f6 d4 25.Rf3 (1.37) (22 ply) 25...Rf7 26.Rg3 Qe8 27.Rg6 Rxf6 28.Rxg7+ Kxg7 29.exf6+ Kxf6 30.Ne4+ Ke7 31.Nxc5 Qc6 32.Re1, or (1.44) (22 ply) 25...Qc6 26.Rg3 Rxf6 27.exf6 Bxg3 28.Qg4 Qc7 29.Ne4 Be5 30.Qxe6+ Kh8 31.f7 Rf8 32.Qe8. In both of these variations, White is winning in the final position.

Schlechter obtained no more winning opportunities in this game. In the difficult endgame that followed, he missed drawing opportunities. This was a difficult game for both players, and a disappointing tournament start for Schlechter.
