Don't know about ChessBase. Under Arena it is menu Levels -> Limit Playing Strength by Elo.

UCI_LimitStrength is handled by the GUI elsewhere. It is part of UCI specification, so changing it to a version without underscore breaks this specification, see: http://wbec-ridderkerk.nl/html/UCIProtocol.html

OK, this makes sense. For me chess per se ends where different movement rules are introduced, and Your "normal chess"
may well end sooner.

So, if I invite you to a chess tournament and you register, and then you shake the hands of your opponent and the game starts, wouldn't you be shocked if the TD came to your board and set up some random chess puzzle from where you have to play, and are informed that the next 19 rounds would also st...

Handicap go is still go. Handicap shogi is still shogi. Hearts of Iron on "civilian" settings with several buffs is still Hearts of Iron. I don't buy the idea that handicap chess is not chess. Game mechanics and rules remain the same, so it is the same game. Otherwise you would have to argue that ch...

No, not much speed gain, 1% for 10 minutes of coding, more if searches are short. Of course I'm not aiming for GM strength (more like a NM plus many weak levels), the app is indeed meant for casual players on cell phones. Out of curiosity, I tested this scheme in a full-blown C++ engine, with the sa...

Hi, Yes, you hear me all right. Currently I am writing a commercial chess app, coded in a slow interpreted language - this has been a requirement and is non-negotiable - so some optimisations are in order. I wonder whether any of you has tried something more sophisticated than always replacing eval ...

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.

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...

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...
