Hi all,

I think I broke something in my engine, but I'm not sure what. Maybe someone has a clue.

When I go towards the endgame, the percentage first fail high drops to below 80% ( normally above 90%)

I'm not sure how to test/ where to look. I switched off bitbases (thought they were corrupt), switched off lazy eval. No improvement.

anybody had this before ?

Cheers,

Tony


You may count fail high % for depth left > N, > 0, <= 0 to eventually get a better picture of what happens. If you cut late, log the moves tried before.

Hi Gerd,

problem is that the first 8 plies still give a decent percentage. So logging kind of blows up. I don't seem to be able to find a specific position that goes wrong immediatly.

I'll try with splitting the counters, that might give some more information.

Thanks,

Tony
