White remains ahead in material with the advantage of the exchange and 3 pawns. In a 3-minute game, however, things can change rapidly.

As we saw last post, Black's best move was to capture White's h-pawn. Instead, he decided to go after White's Queen. 

13.Qh6 Ng4 14.Qg5 Qf8 15.Be3 Qf7 16.Nd2 Rf8 


Black continues to attack. The pressure on f2 is impressive. Therefore, best for White would now be 17.Bxc5 dxc5 18.f3, with a safer King.

17.Qf4 

This is a slip that might be clock related.

17...Nf6 

Black, too, overlooks an opportunity, perhaps for the same reason. Instead, 17...Qxf4 18.Bxf4 Rxf4 would leave him with 2 Bishops for a Rook and 3 pawns. Black's continued pressure on f2 would give him an edge. 

18.Nf3 


Help has arrived. White needs to continue to be careful, as Black still has 5 pieces on the attack.

18...Qe7 19.e5 Ng4 20.Bxc5 

This eliminates the enemy dark square Bishop, but overlooks the attack on the Queen. It is tricky, but 20.Ng5+ Kd7 21. Qa4+ Kc8 first, followed by 22.Bxc5 would achieve White's goals.

20...dxc5

Black reflexively recaptures. White recovers.

21.Qc4+ Kd7 22.Qd5+ Kc8 23.Rae1 Nh6 24.e6 

This "Jerome pawn" is trouble.

24...Bxf3 25.gxf3 Qxh4 26.Qd7+ Kb8 

With his Queen on h4, Black has one last chance.

27.e7 Black resigned


There is more to the position than the multiple threats 28.exf8+, 28.e8/Q+ and 28.Qd8+. The pawn advance also opens up the c8-h3 diagonal again. This is important, because any other move would have allowed Black to take advantage of White's hemmed-in King and repeat checks with his Queen, achieving a draw by repetition.

One possible continuation now is 27...Qg5+ 28.Kh2 Qh4+ 29.Kg2 Qg5+ 30.Qg4! Qxg4+ (if 30...Nxg4 31.exf8/Q+ will mate) 31.fxg4 Re8 32.Rh1!? Nf7 33.f4 b6 34.f5 gxf5 35.gxf5 and White's 2 connected, passed "Jerome pawns" will win the game. (Simplest would involve Rh1-h7 followed by f6-f7, forcing the win of the Knight.)

Quite a battle!
