| Black has just captured on d8 in Spanton (2008) - Norman Hutchinson (2175), Isle of Man 2002. Who stands better, and by how much? |

The position is dead-equal, according to the analysis engines Stockfish12 and Komodo11.01.
27.Bf4?
It was better to start centralising with 27.Kg2.
27...Ke8?
Black should hit the bishop with 27...Ne6. After 28.Bd6+ Kg8!? Black threatens to win a pawn with ...Nd4. White can prevent immediate loss of material with 29.e3, but then 29...Ng5 is strong, eg 30.Kg2 Nf3 31.Kg3 g5, when ...f6 and ...Kf7-e6 etc follow. Instead of 29.e3 the engines prefer 29.Kf1!?, but then Black has 29...Nd4 30.b4 Nc2 and ...Nxb4.
28.f3!?
My original notes show Fritz5 did not like this, but it comes to be Stockfish12's choice (Komodo11.01 also likes it, but equally likes 28.Kg2 and 28.b4).
28...Ne6 29.Be3 exf3 30.exf3 Nc7 31.Kf2 Kd7 32.Bd4 f6 33.Ke3
I offered a draw.
33...Ke6
The position is completely even, according to the engines, but why not play on when you are much the higher-rated player?
34.Ke4 g5 35.Be3 Nd5 36.Bd2
In the postmortem NH suggested 36.f4?, but it loses to 36...Nxe3 37.Kxe3 Kd5 etc.
36...Ne7 37.Be3 Ng6 38.Bd4 Nf8 39.Be3 Nd7 40.Bd4 g6 41.Be3?!
This makes the defence difficult. There were plenty of simple moves that kept the balance, eg 41.b4.
41...f5+ 42.Kd4?
Losing a pawn and the game. After 42.gxf5+ gxf5 43.Kd3 Kf6 Black is better but there is a lot of play left.
The game finished:
42...Ne5 43.gxf5+ gxf5 44.f4 Nf3+ 45.Kc4 g4 0-1
