Simple chess engine in q. A board is a vector of 64 integers. White king = 1, black queen = -2, etc., empty is 0. Algorithm is negamax with alpha pruning. No castling/en-passant yet.

cd q
q server.q -p 3002

To test all:

cd q
q test.spec.q

Run any *.spec.q for partial tests. Start q with -s [n] to benefit from peach.
