I use "fail-soft" alpha-beta, which looks as I gave it. He uses normal alpha/beta. The only difference is that on a fail-high or fail-low, my variation will return a score outside the original alpha/beta window while his won't... but they search exactly the same nodes and get exactly the same score if it is a real score.
