Notice after I play Nxf4 I see it Qa4! ( better than Nxf4)
I don't like f4 , Nf3 ( black is slightly better ) ( Bd3! Nh6 Qxh5 Bxd3 cxd3 black have edge ) ( Nc3!) Nexd2 ( better Qxf2 ) and Ne4
My mistakes 6. Ne7!? 6. Nh6! ( black is slightly better )
Nxf4?! Qa5+ quick win ( black pawn up and active
Notice 2 4. h5 slightly ( pawn sac ıf white play Bd3 ) ( Nh6 idea strong square g4 ( notice h3? Nf4 idea very strong g3 square) better than e6 (notice white can't play g4)
5. e6?! white have edge Nh6! ( Be2! black have edge ıf white play Bd3 black is slightly better black idea play Nd7 Qb6...)
example match lichess.org/IecvY6Ho/black#23 ( after black play Bg4?! white equalize game Notice 9. Nxc5 same position lichess.org/IecvY6Ho/black#2 )
