The innocuous h3 is often the beginning of the end in the ef6 CK

I have won uncountable games with … Bxh3!

Actually it was defendable but they usually struggle. 0/0/0 btw.

Probably better 13. … Ng6 first and if something like 14. Rad1 Bxh3 is much better.

I don't get it

No wonder you won, you got a pawn cube!

Some fellows I talked to thought this pawn structure is bad for some opaque reasons…

Nice tetris formation after black's 16th move :)

Lucky...

15.Qd1. was better and you probably need to go for a draw.
