This sounds right to me.  Perhaps the genlegalmoves function (used for
verification) can be implemented as a call to genmoves, followed by
weeding out the illegal moves by testing each position to see whether
the king was left in check.  genlegalmoves doesn't have to be fast,
since it is used only for testing user input.  (Well, maybe it should
also be used to generate short algebraic notation on output, but
still, it would only be called once per move, or once per move output
in post mode, which is small compared to the number of nodes
searched.)
