This game with NL and Strass was pretty intricate, but I'm stuck on move 17...Bg2f1 ?? I know their must be something here that counterfits Qxf3! hanging a Knight, however I can't find it?
I havn't looked real deep into this, but my thoughts were perhaps Lad didn't like 18. Bc4+ Nxc4 19.Qxc4+ Kh1 20. Rxd8 Rxd8 ?
Still, whites down a knight and I don't see the knockout? I'm sure their are some underlying tactics here that have bypassed my sub 1200 brain! Help!

This is the game in question and the specific position rises after 17w (whites 17th move). Any help/explanation of the underlying tactics here would be of great value!
