Try the following position: BKa1,We3,f4,g1,h2. White to play and win. But CheckersCollection plays 1. Checker e3 - d4 1. partial 3 King a1 - f6 x d4 !?!?!

Hi Aleksey, The maximum quantity capture rule is not mandatory in Russian Checkers: if they are few possible capture sequences the player may or may not choose the sequence that will result in the most number of captured pieces! Cheers, Astrit | |||

Hi! There is the only sequence: 1... a1:e5:g3 (in Russian notation). No choice, no maximum etc. Aleksey | |||

Have you tried the other collection, Checkers Variants? : http://mlwi.magix.net/bg/checkersvariants.htm /Mats | |||

Yes, I've. IMHO, Russian Checkers in your collection is a valid rules implementation. Another valid variant is Russian Checkers by Karl Scherer. I use the zrf-file by Scherer to write russian checker variants. For instance: 1. Free russian checkers - capturing is not mandatory. ---------------------------------- (include "RCheckers.zrf") (variant (title "Russian Checkers - free checkers") (move-priorities) (default) ) -------------------------------- 2. Double moves russian checkers -------------------------------- (include "RCheckers.zrf") (variant (title "Russian Checkers - double moves") (turn-order Black Black Red Red) (default) ) -------------------------------- 3. Giveaway russian checkers with 4 kings (Dames) ------------------------------------------------- (include "RCheckers.zrf") (variant (title "Russian Checkers - try to lose all Checkers(4 kings)") (board (Bdef a3)) (board-setup (Black (King a1)) (Black (King c1)) (Black (King e1)) (Black (King g1)) (Black (Checker b2)) (Black (Checker d2)) (Black (Checker f2)) (Black (Checker h2)) (Black (Checker a3)) (Black (Checker c3)) (Black (Checker e3)) (Black (Checker g3)) (Red (Checker b6)) (Red (Checker d6)) (Red (Checker f6)) (Red (Checker h6)) (Red (Checker a7)) (Red (Checker c7)) (Red (Checker e7)) (Red (Checker g7)) (Red (King b8)) (Red (King d8)) (Red (King f8)) (Red (King h8)) ) (win-condition (Red Black) (pieces-remaining 0) ) (win-condition (Red Black) stalemated ) (default) ) ----------------------------------------------- 4. Diagonal russian checkers ----------------------------------------------- (include "RCheckers.zrf") (variant (title "Russian Checkers - diagonal") (board-setup (Black (Checker c1)) (Black (Checker e1)) (Black (Checker g1)) (Black (Checker d2)) (Black (Checker f2)) (Black (Checker h2)) (Red (Checker a3)) (Black (Checker e3)) (Black (Checker g3)) (Red (Checker b4)) (Black (Checker f4)) (Black (Checker h4)) (Red (Checker a5)) (Red (Checker c5)) (Black (Checker g5)) (Red (Checker b6)) (Red (Checker d6)) (Black (Checker h6)) (Red (Checker a7)) (Red (Checker c7)) (Red (Checker e7)) (Red (Checker b8)) (Red (Checker d8)) (Red (Checker f8)) ) (default) ) ---------------------------------------------- Etc... | |||

Hi Aleksey, If you just replace (option "maximal captures" false) with (option "maximal captures" true) at Russian Checkers Variant zrf code of CheckersCollection.zrf (variant (title "Russian Checkers") ; ; ; (option "maximal captures" false) ; ; ; ) you would get Zillions to play as per your expectation[s]... Here is a new corresponding ccfrusail-1656.zsg file: Zillions Save Game File Version 0.02 HC RulesFile=CheckersCollection.zrf VariantName=Russian Checkers (x a7) (x b8) (x b6) (x c7) (x d8) (x d6) (Second King a1) (x a3) (x b2) (x c3) (x c1) (x d2) (x e1) (First Checker f4) (x e7) (x f8) (x f6) (x g7) (x h8) (x h6) (x f2) (x g3) 1. Checker e3 - d4 1. partial 2 King a1 - e5 @ d4 0 1 1. partial 3 King e5 - g3 x f4 x d4 Note that Zillions now plays: 1. Checker e3 - d4 1. partial 2 King a1 - e5 @ d4 0 1 1. partial 3 King e5 - g3 x f4 x d4 Instead of previous played: 1. Checker e3 - d4 1. partial 3 King a1 - f6 x d4 Cheers, Astrit | |||

Russian Checkers rules are not so simple! See attached files.
caprures true ++++++ attachment +++ 1660 +++ zsg for valid implementation by Scherer ++++++ jpeg +++ 1661 +++ The landing squares after the first capture (invalid) +++  There are two valid landing squares after the first capture, but "maximal captures true" retains only one of them. Once more - there are no maximal captures in russian checkers. | |||

No, I managed to f**k Russian Checkers up too. A Man could not capture backwards as a King, at reaching a promotion square. But now it does. http://mlwi.magix.net/bg/checkersvariants.htm Of course, if you're interested in Russian Checkers, there are stronger programs than Zillions, like Aurora Borealis. But Zillions is decent in checkers games. /Mats | |||

I play checkers with Checkersland and... Zillions. Aurora Borealis has too many buttons and menu items. |
