Somehow my script before didn't execute the command to set a FEN position. On my PII/400 notebook, I get 159.43 seconds. Note that I don't consider this test very worth-while... there are several ways to write this code... I use the Check() function after each move, when it can be written without doing so... I also do a lot of stuff to save a path for each distinct set of moves (root to tip) something I wrote for Stefen J. to help him debug something new he is doing. In crafty, my move generator time is < 10% of the total time, which means this isn't the number that is important for overall search speed...
