I'm sure that this one is not too difficult?
However, it would be interesting to see how Black follows up too if White replies to .....Bxf3 with gf.

Hi Walter,

before Black had the chance to play Bxf3, White played his bishop from b3 to c4.
What would the other engines have played from that position a move before the diagram position?

Cheers,
Graham.

[Paloma]

Hi Graham,

totaly lost position for white, also with bishop on b3:

Hi Graham,

i wonder why the eval Komodo shows is so small, and my Fritz eval so high.

your initial fen above is wrong, no black Rook on c7

Herbert

[Vinvin]

May be Komodo is weaker than other top engines in tactic/king attack
