Slipping Away

The round four battle with Nikolay Bulakh was my most interesting game in the 2023 Eastern Washington Open. He surprised me with 1.c4! and we both made unusual moves that had us out of book by move five. After Nikolay chose to keep his king in the middle, my confidence in the strength of my position soared. After a sequence of parried threats that had us repeating a couple of positions, Nikolay offered a draw.

Black to move

My response to the draw offer was to push a pawn.

27...a5

My silicon friend suggests that 27...Ne7, threatening f6-f5, offered prospects of an advantage. I doubt either of us would have found the engine's line: 28.h3 Bxh3 29.Bxh7+ Kf8 30.Rf2 with a slight advantage for Black.

28.Ng2

28.Bxd5 was possible 28...Bxd5 and several lines that White can choose keep the balance.

28...Nb4+

I continue with the idea  I was pursuing before the draw offer, now with the a-pawn on a5 instead of a7.

I recall glancing at 28...a4, which deserved deeper calculation.

29.Kd2 Rd8 30.Nf4 f5

White to move

31.Bf3 Bh6

By attacking both knights, I threaten to win the d-pawn, but White's defensive resources are sufficient.

32.Be2 Rdb8 

I keep shifting targets, but cannot generate any tactics that Nikolay does not parry.

33.Rfc1

"A strong move", Nikolay said during our postgame analysis during lunch. I concurred.

33...Nc6 34.Nd6

Black to move

34...Rxb3

I had been trying to win this pawn since I opted to defer taking it with my bishop on move 15. After the game, I decided that this move was the critical mistake, suggesting to Nikolay that I should have played 34...Rfb6. Stockfish agrees my suggestion is better, but not decisively so. "Am I in trouble here," Nikolay asked. Our lunch break was coming to an end as round five would be starting in about ten minutes. We analyzed a couple of lines quickly.

35.Rxc5 Bf8 is better for Black. However, 35.Nxe6 fxe6 36.Nc4 maintains equality. I don't recall whether we looked at this line.

35.Rxb3 Rxb3 36.Rxc5

Black to move

36.Ne7?

It would have been wise to play 36...Rb2+ 37.Kc3 Rb3+ when White has nothing better than letting Black repeat the position. Blocking the check on the second rank with the rook keeps Black's outside passed pawn and a knight vs. bishop ending that should be drawn. We would have played it out, of course.

37.Rxa5

Now, White has an advantage. Any chances that I thought I had slipped away. I played another 14 moves as my position grew worse and worse. Then, I resigned and we went to lunch with 50 minutes before round five would begin.

In the last round, Nikolay drew the tournament's top seed on board two, finishing in a tie for second place. I won my round five game quickly (see "Checkmate Exercises"), then enjoyed watching the battles on boards two and three.
