ICC Tactic to beat a GM

Got this position in the 5-minute pool with black against GM Legko who is the very strong Oleg Korneev. I played a ...Nf6 against the Tarrasch variation of the French and found a slightly non-standard tactic for this line.



17...Nh3+!

A good move but only second best, 17...Nxg2!! probably does the job slightly better ;-)

18.gxh3

18.Kh1 Rxf3 -+

18...Rxf3 19.Bh6 Bf4! 20.Bxf4 Qxf4 21.Rcd1 Raf8



And here my position is so overwhelming that even I couldn't blow this despite some decent efforts.....0-1 and a good scalp ;-)
