Hello!
It's a strange game yes. I am not a very good chess player and I don't understand why your opponent place the queen this way in the corner on move 20? He though it would be easy to capture one knight and then exit from there? I think it's the case... A few move earlier, you travel your queen far away to take a single pawn and then again a long travel to get it back I feel he did not really though about it but he probably assume he would do a similar thing... It's a funny situation though. Thanks for sharing, I am happy to have seen that.

Oddities of this game include:
A fianchettoed queen.
Two knights on the back rank.... side by side.
Don't try this at home...
