Integers, Electronic Journal of Combinatorial Number Theory. ISSN: 1553-1732. Vol. 12, nr. 5 (2012)1553-1732http://hdl.handle.net/10400.21/5130Wythoff Queens is a classical combinatorial game related to very interesting mathematical results. An amazing one is the fact that the P-positions are given by (⌊├ φn⌋┤┤,├ ├ ⌊φ┤^2 n⌋) and (⌊├ φ^2 n⌋┤┤,├ ├ ⌊φ┤n⌋) where φ=(1+√5)/2. In this paper, we analyze a different version where one player (Left) plays with a chess bishop and the other (Right) plays with a chess knight. The new game (call it Chessfights) lacks a Beatty sequence structure in the P-positions as in Wythoff Queens. However, it is possible to formulate and prove some general results of a general recursive law which is a particular case of a Partizan Subtraction game.engCombinatorial Game TheoryPartizan Subtraction GamesWythoff Queensjournal article10.1515/integers-2012-0021
