I needed some convincing but finally I've implemented lazy SMP!

How much gain in elo does it give?

How much gain in elo does it give?

That's a good one because I didn't test this as thoroughly, but I hope/think 40-50 elo for every doubling of threads.

Well done!

Congratulations,

Finally you implemented multi threading for chess22K!. In order to try to get not to much behind you the next CSVN tournament, I will have to start with the development of an evaluation function now....

When can we expect the release of your engine?

The last thing I wanted to do is to play with Texel tuning for "all" my evaluation parameters. Unfortunately I had problems with the watercooler so I could not test any results. Today I changed the cooler to an air cooled one, so finally I can start testing with the Texel tuned parameters.. Depending on the results, maybe next week.

I just noticed that 1.10 has a score of 3000 elo on the CCRL 40/4 list (single-threaded)! Wow!
Since about half a year this was my goal. 1.9 was kind of dissapointing and making it better was getting tougher and tougher. That was one of the reasons to make it multi-threaded, I had to get to 3000!
Apparently the minor changes I’ve implemented, also for multi-threading compatibility, made it quite stronger. I’m a happy man!

I will be reluctant to use your engine in the future. What would happen to your happiness if it sank to 2999...

I have taken a picture as proof

This just happened at the Junior League: https://clips.twitch.tv/WiseVivaciousPistachioDatBoi

It's still chess22k 1.9, but you may want to take a look... it was a HUGE blunder. The game was completely won by chess22k, and that move threw it out of the window.
