Hello, I found it is hard to find information on bitboards... I have found lots of infos on search algorithms on the web and I also bought "Scalable search in computer chess, by Heinz". However I would like to master bitboards and I cannot find any good source. Do you know any book/article/web-site which I could buy/download? As always, thank you very much!

Hello all ! I'm programming an engine and I'm wondering if what I do concerning my list of move is somewhat efficient... When generating moves or attacks, I need to store the moves in a list. Maybe I'll have to sort this list later also (I'm not there right now).

Bobby Fischer thought that Fischer Random Chess was the antidote to computer software using opening book theory to prove they can't play chess well. I beg to differ. Please look at this game I played today using the Fischer Random setup. Unfortunately my engines can't read Fischer Random castling rules so I had to play this setup as if it was shuffle chess. But as you can see, this game should be...

In the bitboards thread there was a mention of the 0x88 approach. I this the approach that the turbo pascal gamesworks used. I am thinking about trying to translate that program to c# as a method a learning about the chess engines and at the same time improving my c# skills. Would the gameswork engine be worthwhile to spend time on. I would not use the old dos screen interface, of course,...

I have a problem, I have loaded in a fritz 8 opening book 117,797 games which includes only winning games for white with the 1.d4 only. Fritz 8 however loses so many times in online tests that I make. The book has the 25 first movements of 1.d4 and leads all in 1-0.Fritz 8 plays all the time with white. There are 117,797 games inside this opening book that i call "D4 KILLER" so what gonna do...

I have matched my old Fidelity 2100 against my PC running Rebel 12 for Dos. Even when I run Rebel 12 at just 5 seconds per move and allow my Fidelity 2100 to run at its highest level outside of infinate which is 3 minutes per move, it is still just no match for Rebel 12 and its 2650 rating on my old Pentium III 400MHz. In game after game Rebel 12 wins. It is just amazing to see just how powerful...

I am still having issues with understanding transposition tables. I never fully solved the bugs in the last engine and now am running into similar issues the 2nd time through. My understanding is that the flag of the entry should be based on the following: beta - LOWER alpha - UPPER in the window - EXACT

Hello, I use the Fritz7 chess program. There you can choose an engine, for example Crafty 17.3. I copied the nalimov tablebases in an directory c:\Nalimov and now for all 3-, 4-, 5- and some 6-piece-ending the result for all moves are shown in the gui. The not working 6-piece-endings are from Dec. 6th, 2002 or younger.

Hello Everyone, I'm trying to use Fritz to improve my play, and was looking for some opinions as to which engine is best at positional play? Also, in order to supplemnt the learning, which player does everyone believe is the best at positional/strategic play. I've read that Capablanca was a fine positional player, but just looking for some add'l opinions. Also, would anyone recommend any books...

Hi, I was downloaded recently some endgames from Internet, site was http://www.uni-klu.ac.at/~gossimit/c/ (*.zip), but after opening i get only some files with PBN extension.

I have a several chess tactics books that I am (tediously) putting into chessbase -- I can use them in high school coaching drills. On the web, I found all the positions from "1001 Winning Sacrifices and Checkmates" (Reinfeld) in PGN format. Are there libraries of other books, or am I stuck entering them by hand? I am especially interested in books I already own. Two examples are...

Hello, I don't understand how to make this work. It's either being in CB8 Fritz8 analyzes with me but is not playing or I have to switch from CB to Fritz which is not want I need (I need to stay in CB). Thanks! Denis

I'm actually thinking over generating the complete state space of another game, but I figure the principle is probably the same for chess endgame databases. What is done when an "infinite loop" is encountered in the state space while generating an endgame database? That is, when it's (for whatever reason) most beneficial for each player to just keep repeating the same states over and over. How...
