I played White here and wanted a little fun, so I played one of my favorite, sharp lines: the Queen's Gambit! Here, I had a deadly attack.

17....Nh5?

and then you kept missing the rook sacs on g6 on move 20 +

at least you made a note of it =)

way to take advantage of too many open files above the king.

Thanks. And actually, even according to Fritz, Nh5 wasn't that bad of a move. The only better move was g6 which requires Black to still sacrifice a knight after 18. f5 Nfd5 19. exd5 cxd5 20. Qd2 exf5 21. Bxh6 Re8 which puts White 4 units up still

You played well. But yes, you did miss some opportunities for sacrificing your Rook and ending the game sooner.
