What a Mess

I had White in this position with the move in a three minute online blitz game yesterday. We had each used just over a minute getting here.

White to move

Black has two extra pawns, both passed, but perhaps White's piece activity balances matters somewhat.

27.Bxf8??

Simplification into a major piece ending does not help when two pawns down, but what else was White to do?

The immediate 27.f5! was a consideration, but the optics of an exchange on d6 gave me pause.
Attacking the queen with 27.Rc7 was also worth considering.

27...Rxf8-+ 28.f5 gxf5?

28...exf5 was best

29.gxf5 Qg5+ 30.Kf1??

Here, simplification into a rook ending was the correct idea. 30.Qg3 Qxg3 31.Kxg3 and Black's extra pawns have little prospect of advancing.

Black to move

30...Qc1+??

Black does not perceive that he has the advantage. 30...Rfc8 shows that White's king lacks protection. After the subsequent 31.Rg2 Rc1+ 32.Kf2 Rc2+ 33.Kg1 Qxg2+ 34.Qxg2+ Rxg2+ 35.Kxg2. Black's extra pawns are decisive.

31.Kg2 Qg5 32.Kh1 Qc1+ 33.Kh2 Qh6+ 34.Qh3 Qxh3+ 35.Kxh3

Black to move

Are rook endings ever simple?

35...a4??

35...exf5 36.Rxf5 a4=

36.f6??

White thinks that this move helps confine the king when, in fact, it allows Black to pursue an attack with Rab8. 36.Rg2+ leads to checkmate.

36...Kh7= 37.Rb4 Rh8??

Black must think that his king escapes check with a discovered check.

37...Rab8 and White's only recourse is a perpetual. 38.Rh4+

38.Rg2!

Cutting off the king. 

Black resigns

A few of the positions in this game and in the analysis should prove useful for the young players whose after school chess club begins this afternoon.
