It so happens that in mine is it as easy to avoid as to not avoid, so I avoid it. I doubt it matters much. If you avoid it, you still have path-dependent scores in your hash table, which will cause search instabilities. As far as I can tell it is impossible to avoid this without hashing the entire path taken to get to the position, which is insane and likely wrong. bruce
