Your while loop looks fine. My guess is the setup code is buggy.
setting up at1, de1 ....
Assuming you call with white to move after 1. e4, d5 and the setup code
is correct and you call as v = see(d5) before making any move:
at1 should be 1
de1 should be 1
so your while loop should work:
There is a defender (queen). value = 1000 and value of capturing
piece is 1000. Thus, value = 0 and at1 drops to 0.
Thus returning 0.
Since you get -8000, it seems it thinks it can capture the queen with
a pawn and the pawn is then captured. Or maybe you have the attacker and
defender arrays swapped (that would cause -8000).
