Re: New uci engine: Rofchade

Nice - big congrats! It's impressive that you've got so far with only PSTs. One super-small point: I notice that Rofchad will return a best move if it finds a mate in analysis mode. Strictly speaking this shouldn't be the case for a UCI compliant engine, although it is really a few flaws of the UCI ...

Re: In Praise of The King

The King has always been one of my favorites. I'm quite sure Johann discovered some tactical tricks that no other engine uses. I only wish he'd create an official UCI version. I had a chat with Johann at the 2015 WCCC. He was pretty adamant that he wouldn't be releasing a new version - such a pity. ...

Re: Time Management and Move Selection

I believe Ed Schroeder did something similar in his engines. You might also look in the hash table to see if the candidate for a single move was an exact match with sufficient search depth.

New WCCC Version of The Baron Released (Plus Polyglot Opening Book)

Richard Pijl has been kind enough to released The Baron 3.43. This is almost identical to the version that played in the 2018 WCCC. Here are Richard’s release notes: Changes since 3.42: Bugs solved: Pin detection in evaluation only detected close pins. Handle spaces in the syzygy path Slightly more ...

Re: World Speed Chess Championship, WCSC and WCCC

Can someone confirm that "Boot" is still written in Pascal / Delphi?

Ryzen 2 and BMI2?

The first generation of Ryzen processors are extremely slow at executing the BMI2 instruction set. Does anyone know if this has been corrected in Ryzen 2 chips?

Re: the annihilation of Stockfish with queen sacrifice 2018

If the post title was simply, "human beats StockFish" I wouldn't blink and eye. Instead it was click-bait claiming an "annihilation" due to a "queen sacrifice". Of course I'd like to see such a game so I played through it. Only to find it was a win on time. Not only that, Pablo wasn't winning at the...

Boring to watch in real time, but it does show nicely how engines can still be outsmarted.
It's a loss on time. Hardly outsmarting the engine.
