Thanks for the comment, I'm glad you enjoyed it!

Actually, my memory wasn't a factor so much. I've hardly studied those lines at all (it's one of the bigger holes in my repertoire, as I also don't see the Torre Attack too often), and I was improvising OTB. Fortunately, my opponent didn't seem to know the lines too well either - i.e. playing 6.Nbd2 instead of what I now know to be the main continuation of 6.Nc3. Apparently black scores quite well in these lines (better than white by a somewhat significant margin, though I don't have Elo ratings in front of me on the quick check I just did), but  I didn't like my position too well after say move 5, and only thought I was doing well a bit later. Basically I was just relying on general positional principles, and I think I flatly outplayed my opponent slightly through 17 moves.

Actually, my 36th move wasn't all that great - from what I can tell, it was the same, with best play, as taking the knight right away; I simply preferred taking b2 first to limit white's options very slightly and win instantly in the very very very unlikely event that my opponent missed the back rank mate.

Wow! I am seeing the Torre Attack after a long time!

You must have phenomenal memory to be able to play the Classical Defense, Nimzowitsch Variation in OTB!

your 36th move was fantastic (it took a moment for me to understand - I thought "duh?"

nice and exciting finish
