I have actually tried this. It's not a winner, but at least it works, and the stack doesn't blow out too badly. What game is it for? In chess you have a max of 30 or 31 captures in any given line, so it's self limiting. I suppose some games might have much more material to get rid of? Actually my chess program tests how deep it is in the tree. If it's more than about 70 plies it prints a message to the log file, then just does a static eval and returns. This might be useful for debugging this sort of problem.
