|Pawn and Two: Swiderski got into difficulty early in this game.
Instead of 8.Nc3?, with an edge for Black, Fritz recommended 8.c4 0-0 9.Nc3 with an approximately equal position.
At move nine Fritz preferred: (-.31) (22 ply) 9.Bd3 e5 10.e4 d4 11.Nb5. Instead, Swiderski slipped with: (-.56) (22 ply) 9.Nb5 e5, or (-.54) (21 ply) 9...Qe7.
At move ten, the situation became more serious. Fritz preferred (-.44) (21 ply) 10.Bd2 e5 11.c4 Bf5 12.cxd5 Nxd5 13.Rc1 Rfd8 14.Qb3 Rac8 15.Rfd1 h6, or (-.46) (21 ply) 10.c4 dxc4 11.Bxc4 e5 12.Bd2 Bf5 13.Qa4 Rfd8.
Instead, Swiderski played: (-.95) (21 ply) 10.b3 Rd8, and Black's position looks threatening, as he is about to advance his e-pawn.
After 11.Bb2 e5 12.Qc1, how should Black continue?

Fritz indicated that Black could best maintain his advantage with: (-.85) (21 ply) 12...Bg4 13.h3 Bh5 14.Re1 Rac8.
Instead, Znosko Borovsky played 12...Ne4?, and most of his advantage was gone: (-.11) (21 ply) 12...Ne4? 13.Rd1! Bg4, (-.10) (20 ply) 14.c4 d4 15.Qc2. After the move 12...Ne4?, White played 13.Rd1! and 14.c4, equalizing the position.
After 15.Qc2, Black had several choices that would maintain an approximately equal position.
Here are three of his choices: 15...dxe3 16.Qxe4 exf2+ 17.Kf1 f5 18.Qc2 e4, or 15...Ng5 16.Nxg5 Qxg5 17.Bxg4 Qxg4, or 15...Bxf3 16.Bxf3 f5 17.Bxe4 fxe4 18.Qxe4 dxe3 19.fxe3 Qg5.
Finally Znosko Borovsky selected a fourth alternative: (-.08) (22 ply) 15...f5 16.exd4 exd4.
After all these complications and difficult choices, the players found themselves in a position that was almost equal. One might think the game was just getting started, but it was not to be.
