would 5...Be7 be OK for Black?

3...exd4 4 Nxd4 g6 5 Nc3 Nf6?! (5...Bg7 is better) transposes to the game S.Ganguly-V.Stjazhkin, Budapest 1998, where White continued with 6 Bg5

Why is 6...h6 actually a losing move for Black?

Can you discover why the plausible-looking 13...Bd7 is actually a losing move for Black?
Reader's Challenge P6.4.1: "Helpmate!"
|
|
A "helpmate" is basically a sequence in which one player actually helps the opponent to achieve checkmate. Starting with a deliberately bad move for Black in response to 11 0-0-0+, can you find a helpmate in which White delivers checkmate at move 13?

5...Be7? actually loses to 6 Bxf7+!! Kxf7 7 Ne6 Qe8 (7...Kxe6 8 Qd5+ Kf6 9 Qf5#) 8 Nxc7 Qd8 (8...Qf8 does not help because of 9 Qh5+ g6 10 Qd5+ Kg7 11 Ne6+) 9 Qd5+ Kf8 10 Ne6+, and it's quite amusing that after 10...Ke8 White has an even stronger possibility than 11 Nxd8, namely 11 Nxg7+! Kf8 12 Ne6+ Ke8 13 Qh5# or 12...Kf7 13 Qh5+! followed by 14 Qf5#.

13...Bd7? actually loses to 14 Nf5! Bxf5 15 exf5 Rfe8 16 Rxe7! Rxe7 17 Bxd6, and this really happened between the two grandmasters involved in game G6.3.1.

11...Ke7? 12 Bc4 Re8?? is an extremely co-operative way for Black to allow the pretty checkmate 13 Bc5#.
