title: Negamax freezes
body: <p>In a game I've created Negamax works well for low depth searches but larger depth increases causes it to freeze. I thought about changing depth to type 'long' instead of 'integer' but not sure what else I can do. I know computation will take longer so it is possible it is calculating behind the scenes and I'm interpreting as freeze up. Any advice would be appreciated. In the game a player can only make 1 of 3 possible moves in a position and it is not like chess where there are large numbers of moves possible in anyone position and terminal position is difficult to reach.</p>
  
  <p>Thanks</p>
