Re: The Fine Art of Chess

This was NOT a good moderation decision. I don't necessarily agree with everything Lyudmil wrote, but his incessant pushing of the idea of pawn chains helped Rodent at some stage. This book might contain something of similar value, so information about it should be accessible right on this forum.

Re: Slow Chess Blitz Classic

I must say I'm impressed. Watched a couple of bullet games between Rodent and SlowChess, and Your engine seems a perfect opponent for Rodent, showing where my brainchild goes wrong. When Rodent attacks, SlowChess keeps its cool. Where Rodent thinks it has a won endgame, SlowChess proves the poor mou...

Re: Rodent IV beta

As of usability of options, it comes in two flavours, for power users and for casual players. Most of Chessmaster users were probably perfectly content with picking predefined opponents, but to have them, somebody needs to tweak them first. Had the Komodo team given us Komodo Tal and Komodo Petrosia...

Re: Fruit and derivatives list !

Some time ago I tried to add more modern search to Fruit 2.1: https://github.com/nescitus/growing_fruit
Count this project as abandoned, but it was fun to see good old Fruit calculate a couple of plies deeper.

Re: Rodent IV beta

A free program that delivers features not seen in most commercial software! This is extremely puzzling to me. Everybody seems to remember popularity of Chessmaster franchise. Implementing personalities is not that difficult, as long as search can deal with asymmetric evaluation. Part of tuning can ...

Re: Collecting labeled positions help wanted

I may try to add some positions, but I wonder whether process of finding them can be automated. Say, take two vastly different Rodent personalities (Tal/Ampere for tactical moves and Chloe/Defender for positional ones) and pick positions where they differ.

Re: Rodent IV beta

And this is Ampere, attacker who cares for pawn structure, tossing an exchange just like that. [Event "Ampere"] [Site "LAPTOP-37HCIE2D"] [Date "2019.08.25"] [Round "9"] [White "Fruit_21"] [Black "Rodent-iv"] [Result "0-1"] [BlackElo "2200"] [ECO "E11"] [Opening "Bogo-Indian"] [Time "21:34:00"] [Vari...

Re: Rodent IV beta

This is Nimzowitsch getting away with an over-engineered opening: [Event "Nimzo.at"] [Site "LAPTOP-37HCIE2D"] [Date "2019.08.30"] [Round "7"] [White "Fruit_21"] [Black "Rodent-iv"] [Result "0-1"] [BlackElo "2200"] [ECO "B29"] [Opening "Sicilian"] [Time "14:16:33"] [Variation "Nimzowitsch, 4.Nc3 Nxc3...

Re: Rodent IV beta

This is a sample game of Cloe personality against Fruit 2.1. Cloe likes closed positions, plays King's Indian and French defences and can do things with them knights! [Event "Cloe.at"] [Site "LAPTOP-37HCIE2D"] [Date "2019.08.30"] [Round "12"] [White "Rodent-iv"] [Black "Fruit_21"] [Result "1-0"] [Bl...

Rodent IV beta

This is a preview of the version that I am going to release soon, after updating web page, documentation, creating a few more personalities and perhaps adding some more stylistic options. As of now, there's only a download link: http://www.pkoziol.cal24.pl/rodent/Rodent_IV_beta.zip After I complete ...
