There is a missed mate for you to spot. It was funny since my play was based around this and when I got the chance I played something else. Not that it did matter.

I like the aggressive opening. I had a few comments:

After he plays Qe7 it looks like he's going queenside. Maybe you could wait on h4 and try to get some queenside pressure with something like Nb5 (threatening c2). Not sure about the specific lines, but it's worth looking into.

Also after he castles, I think this is a critical position to think about. I liked playing on the kingside although maybe you could've done something in the center.

I liked h6 but after he plays Qe8 you need to play e5 (which is crushing, probably wins a piece). If he takes on e5 with the pawn, you recapture and the pins are too much.

Also, avoid trading the Bg5, his position is cramped and he's looking to trade, play Be3 or something.

I like your plan with d5 (after Kxb7) although Qb5 right away would've worked too I think.

Nxb5 is a really nice move. If he takes on b5, you can just play a6 and he's getting mated. (EDIT: I assume this is the mate you're talking about)

Nice game! I liked the tactics.

Thanks for you comments, you pointed out a couple of things I had missed:

Nb5 looks good and it is what I should have played instead.As you said e5 was winning, it was a simple miss.I should probably not have traded the g5 bishop as you said. I didn't think about this but more accurate would probably have been Be3 or something. I looked at Qb5 first but I actually think it's necessery to play d5 before Qb5. He could ofcourse not take the knight on b5 because of mate but when he did I ofcourse recaptured with my Queen. I haven't slept much for a while, maybe I can blame it on this.

I think after Bg5 Qe8 you had e4-e5 winning a piece(instead of Kb1).

oh,that was mentioned before,sorry:)))
