I let shredder think for 8h on this position, because i was not convinced by
short analysis that 18. Nf6 is really the best move; here's the 2 best moves
after 8h :
Analysis by Shredder 8:
1. ± (1.13): 1.Cf6+ gxf6 2.Fh4 Te6 3.Tg3+ Rh8 4.Dg4 Fh6 5.Dxe6 fxe6 6.Fxf6+ Fg7
7.Txg7 h5 8.Td1 Df8 9.Tf7+ Rg8 10.Txf8+ Txf8 11.f4 Rf7 12.Rf2 Rg6 13.g3 Rf5
14.Re3 a5 15.h3
2. = (0.25): 1.Te3 Te6 2.f4 Db7 3.f5 Tee8 4.Cf4 Da7 5.Dxa7 Txa7 6.Ff2 Tb7 7.Ch5
d6 8.e6 fxe6 9.fxe6 Fd5 10.Cf4 Fc4 11.Td1
short advantage, may be not enough to win yet ...
