? Blacks opens passively

Pins knight-indirect E4 pressure

B file for white. a6 earlier weakens b6 pawn

? Black is grossly underdeveloped at this point.

If black takes the knight, his g and h pawns will be off the board, the f6 knight will be pinned and white will be looking to play e5 or qf4. Even if black doesn't take the knight castling kingside is probably not going to be feasible. Blacks lack of development and surplus of moved pawns is now showing.

fxe3 was also considered but hampers the queen

?? hangs d6

? NxB7 was the best move here. nxf7 allows for qg8 threatening qxg2 mate. For the rest of the game black does a great job keeping pressure on the white king. OTB white likely would have missed one of black's shots. White play carefully and wins.
