Actually you guys look even... why he moved Knight to d2 is questionable but still developementwise its even.

Usually in QP games obstructing that c-pawn is not good, except for in chigorin. That Knight is better on d7, as it prepares e5 and c5 advances.

What would u recommend then?

Don't forget... you had to move the bishop twice as well.

Trading Bishop for Knight I feel is unnecessary. e5 instead here seems good, undeveloping his Knight & he would have a cramped position. + u get to trade off his good Bishop for your bad-ish Bishop.

u are doing well, making both his Bishops feel awkward.

I think u should play h4 & open the file for your Rook, nice & simple.

This would be a good move if u were going to play h4 next, then that h2 pawn would really come under attack.

You could have considered king side attack, with 0-0-0, h4, and maybe Qf5 (to bring the queen at h-file), but then again, the g-pawn might have been better on g5 in this case, supporting the h-pawn hack.

?? Really castling is just a waste of time here and especially K-Side (moppa was referring to Q-Side), just play h4 and as moppa said Qf5-Qh5 after opening the file, win.

What u came up with however is a creative way of getting your Q on h3.
