15|10 isn't a time control that I ever play, so when I actually did, yesterday, I had to be a derpyderp and wade into a thicket of calculation-intensive variations that I'd need 5–10 minutes per move to play well.

Mistake #1: I spent about a minute on move #10 deciding whether to castle queenside and go for the Yugoslav or castle kingside and play the Classical.
Mistake #2: I tried to make 18. Ng5 △ Nxe6 work when I couldn't calculate a clear win, when I intuitively felt it wouldn't work, and when I usually need 10+ minutes of thought to calculate moves like this well.
Of course, by then I was already in time trouble and missed both 25. c4 and the fact that the "combination" I played on moves 26 and 27 is totally unsound, because after a move like 27...Rf4, taking the knight is impossible in view of 28...Re8 and back-rank hell.
I thought Black played pretty well for his rating (~1400), but I'm ashamed of myself.
