White to move.
this is an adapted position taken from Tal v Smyslov 1959, the only difference between the position in the game (after 21.Kg8) and this position is that I have moved the black Knight from f6 to b6.

Crafty gives the line: Rxa1 Kxf7 Rhe1 c5 Re4...[41m nodes : scores 3.47]
However, I was wondering how many other "human" players would disagree. In my eyes there is a powerful imbetween move crafty missed.
Nh6+ gxh6 Rxa1 Bg4 ...
the idea being, to spend a tempo in order to damage blacks pawn structure. [doubled up h-pawns]
Crafty on the other hand, seems to think this variation is marginally weaker [60m nodes: scores 3.25]
This is only a small difference but it does mean that, had crafty beeing playing white in this game, Nh6+ would have been 2nd choice and therefore not played.
which begs the question: who thinks crafty is right? and also, who else would play Nh6+ in this position?
