Title: return immediately after feeling claustrophobic

The way isFree is used it has the same effect as a return. But instead of immediately returning, it finishes the for loops and goes through an if to the end of after_place_node. Nothing happens after it is set except for spinning some wheels. Using a return is slightly more efficient and does the same thing, not place the board.
