Unfortunately I cannot guarantee the ELO performance being same as v1.6. Bug #2 was deep inside the move generator code and caused some moves to be searched twice (not just at the root, but everywhere in the search tree) with an associated performance hit.


Although this will force testers to retest the engine, it's hard to imagine the bug fix resulting in a decrease in ELO.

Thanks again for your work, Richard.


Hi,

Unfortunately, from my tests at ultrafast TC and bullet with no increment, basing on many hundred games, it seems that 1.6a could be weaker around 10 elo compared to 1.6, with ponder ON and perhaps even more with ponder OFF (but less games tested in this case).

I noticed that the number of knodes calculated by 1.6a is almost always lower than 1.6. I see that generally the evaluation is different.

I did always games 1.6a against 1.6.

I'm afraid ipon chess will confirm this
decrase. Sad

Anyway of course thanks to Mr Vida for the efforts to solve the bugs reported.

Best Regards


The 10 Elo drop is not an issue if the bugs are sorted out....
Dr.D
