I tried with Crafty 16.3 as a Fritz engine and it does not clear hashtables
after new move in auto232. It's easy to check this manually too. A funny thing
with 16.1 is that it clears hashtables on my PII-400s and not on my portable
P150MMX. If you can explain this to me...

Still waiting for the first one you lost... What was it? A Ferrari, we said?
