Re: AlphaZero SF game 10 Does Your Engine Find 29Qh3?

Ok thanks
Dirty found g4 and it looked good,I just wondered if there was some defence it might have overlooked.

Re: AlphaZero SF game 10 Does Your Engine Find 29Qh3?

Also after 34..a6 kaissa found the idea 35. Rd3 and Rf3 for white.
But not after the move 34..a5 ?!
I guess it should still work?

Re: Any news of a Komodo update in sight?

Are you serious ? Really who cares anymore whether Komodo or any other Engine gets updated anymore unless they incorporate MCTC algorithm into it, instead of the now obsolete Alpha-Beta Search. Is your real name Rolf Tueschen? afaik he did not (re-)start another kasparov-deep thought discussion,so ...

Re: assert

Hi, I'm looking to improve my program. For that I'm adding asserts all over the place to check input variables, outgoing values, and so on. I've also added an assert that if we're in a null move, then beta == alpha + 1. My question now is: what other things are there to check for? regards The last ...

Re: LMR and killer

Is this standard?
I have tested making an exception for killers a couple of times but it was always worse in Dirty.I guess if the first N good captures fail the killers just won't help, except when there are no good captures but then the killers would be on the top of the movelist and not be reduced.
