You are wrong. Or, rather, your tactical database is wrong. Here is the position again: [D]4rb2/1p1q1ppk/p1n1p2p/2p1Pn2/3PNR2/2P2K2/P2QBP2/6R1 w - - 0 1 There is ABSOLUTELY no forced mate in 5 moves. There is not even a forced mate in NINE moves from this position. 1.Rxf5 is a good test move for computers, but there is NOTHING that forces Black to reply 1...exf5. Secondly, even if Black DOES reply 1...exf5, it is not a Mate in 4 from there, as you claim. Here is what you posted: ------------- 1. Rxf5 exf5 2. Qxh6+ Kxh6 (2... gxh6 3. Nf6+ Kh8 4. Rg8#) 3. Rh1+ Kg6 4. Kf4 Qe6 5. Rh8 1-0 ------------- 1...Nxd4+ is BY FAR the best reply to 1.Rxf5. It appears to be the only move to give Black a fighting chance. If Black foolishly replies 1...exf5, then the following is forced: 2.Qxh6+ Kxh6 3.Rh1 Kg6 4.Kf4 Now Black has six different moves that will all lead to mate in THREE more moves for White. Here is one example: 4...Qe6 5.Rh8 Qxe5+ 6.dxe5 fxe4 7.Bh6# So, your initial position is a mate in SEVEN moves, but ONLY if Black replies 1...exf5 (or something even worse than that). If Black replies 1...Nxd4+, then White will almost certainly win, but there is a lot more chess to play.... For example: 2.cxd4 exf5 3.Qxh6+ Kxh6 4.Rh1+ Kg6 5.Kf4 Qc6 6.d5 Qf6! 7.Bh5+ (if 7.exf6 Rxe4+! 8.Kf3 Kxf6 0-1) 7...Kh7 8.Nxf6+ gxf6 9.Bxf7+ Bh6+ 10.Rxh6+ Kxh6 11.Bxe8 1-0 -- but mate is still quite a ways away.... jm
