The following line was published on one of the rec. chess groups about a year ago. Although the line is definitely not sound against accurate counterplay, I've had succees with it in 5 minute blitz games against heavy weights such as Crafty 15.20, Phalanx 18, Gnuchess, Gromit, Exchess, Ychess, Rebel Decade2.0, Mirage, Rookie, Zchess .. the list goes on (but neither Chessmaster 6000 nor Fritz 5 appear to fall for it). Here is my win against Crafty 15.20 (Pentium 133Mhz, 32 Meg Ram and using the 5,7 meg book bin file for Crafty - which is available at the crafty download site - and no tablebases). 1 e4 e5 2 Nf3 Nc6 3 Bc4 Nf6 4 Nc3 Nxe4 5 Nd5 Bc5 6 d3 Nxf2 7 Qe2 Nxh1 8 Ng5 0-0 9 Nxc7 Qxc7 10 Qh5 Bf2 11 Kf1 h6 12 Bxf7+ Kh8 13 Qg6 Ng3+ 14 hxg3 hxg5 15 Qh5# A I recall, the critical moment is after 9 Nxc7 where if black does not take the knight, white's game falls apart. Of course, after 9 ..Qxc7, black can no longer prevent the mate. It seems however that many chess programs are just too greedy to explore the consequences of taking the knight fully.
