Incredible move -- very well played. Out of curiosity, would 24.Qe3 have held for White? CM9_R1 generally follows the game's moves after 18...Rae8. But after 23...Re5 we have: 24.Qe3 Qg4 25.gxf3 Qh3 26.Rg1 Rh5 27.Rg2 exf3 28.Qe6+ Qxe6 29.dxe6 fxg2+ 30.Kxg2 leading to a Rook v Knight endgame which may give White drawing chances. I didn't have time to work it through to a potential conclusion.... Thoughts? jm
