Hi Ed, I'd forgotten all about Q3! Which version of ProDeo did you use for this Q3 test?
The regular ProDeo 2.2
Also, have you tested MACHEID or any other personalities? :)
Because of this thread I am looking in those old ones too :wink:

A lovely one. MChess Pro 5.0 won the 13th World Microcomputer Chess Championship 1995 in Paderborn.

One or two oldies can still remember competing against MChess in Don Beal's tournaments before that...

Conclusion:

Olithink is a great engine and definitely being added to my preferred sparring partners.

Weak king safety combined with solid positional play and excellent defense (and falling into traps occasionally!) makes it the perfect human-like sparring partner.
Thank you very very much for this great analysis and the presentation of two very interesting games.
You are really a great chess player, much better than me.
- Weak "king safety", but a great defender. Gives humans a feeling that we can get *close* to forcing checkmate, unlike "perfect" engines.
It must be quite a special "feeling" for a strong chess player like you to play against engines like Stockfish. How would you describe it?
Is it any different as when you play Leela?

Against which (SF/LC0) would you rather win?


PS I hope we see more of your human like chess engine :) Looking forward to it.

I am weak at chess, I am interested in an engine with which will sacrifice a bit just to just charge down and get mate as quick as possible.

Is there any engine which comes close to doing that ?
You can use a medium strong engine like OliThink and start with an advantage, let's say the engine is one knight down. Of course, every engine that understands either UCI or CECP can do this.

This game is self-explanatory, but there was a funny trap our "mystery engine" set, which poor Oli fell right into.

Playing 48.g4!? here looks ridiculous, but of course, with the outside passed pawn on the a-file we can afford to set such traps.

Since 48...Qxg4+ is losing, I guess white's move is also objectively decent as well.


This is a tactical flaw, OliThink needs depth == 26 and a lot of time to see the trap:

Obviously 51. Kf3 in the winning line is a victim of too much pruning.

Would you in addition need to set contempt level so that it should do that ?

No, you just you your chess gui to load or set up a position. Remove an opponent's knight and start the game.
