Positionally crushing my opponent.

I am really proud of this game where I crushed my opponent and all he could do was sit and watch.

Criticism encouraged

Looks like a very smooth game to me. The only move I didn't like was 12. ... d6. White could have countered with 13.dxe6 Rxe6 14.c5! and he has some pressure. 12. ... Na6 was the better choice. Also, you missed a mate in 2 after 29.Rg1, but you are winning regardless. Congrats :)

Makes me want to learn the Nimzo-Indian :D Your knight was all over the board!(in a good way)

good game indeed, but I feel like your opponent wasn't really trying hard, especially when he just lost a tempo with his rook for nothing

Exactly, no crushing here from black, but just white doing nothing.

@KiyoakiMatsugae comments aside (well said) given the play your opponent made I really like your strategy. Constrictor. Awesome.

6...b6 fails to 7 Qg4 with double attack on g7 and Ne4, so you had to take 6...Nxc3 first.
12...d6 is indeed questionable after 13 dxe6. Here is an example of the same position reached by transposition
