It is the right move.  But you have to evaluate passed pawns very highly to
get this one, as you really will not search it to a queen in any finite amount
of time, due to the checks.  I have seen older versions of crafty solve it.
Someone reported that if you do "eval ppscale 200" then it will get it pretty
quickly...
