As programmer, give some user interface (UCI has this in the protocol), that marks allowed moves at the root. Only consider allowed moves in the search loop at the root. As a user: use the provided Interface :-) Under Shredder 5 GUI, in Analysis mode, push shift, and at the same time execute the move, that you disallow. You can repeat this with more moves. Yace text mode GUI. type ; eml = "edit move list mode" eml 1 setb 1k4Bq/6pP/3p2Pb/3P1Pp1/1K4P1/8/8/8 b - - 0 1 ana ; you will see 1e: Qxg8 2e: Qxh7 3e: Kc8 4e: Ka8 5e: Kb7 6e: Kc7 7e: Ka7 ; showing, that at the moment all moves are "e"nabled. ; type 4 ; to disable move number 4, Ka8. You will see 1e: Qxg8 2e: Qxh7 3e: Kc8 4d: Ka8 5e: Kb7 6e: Kc7 7e: Ka7 ; note the d in front of Ka8 ; you can repeat this with more moves. ; hit Enter, to show, you are finished with the editing of the move list ; and a search with only the remaining 6 moves will be started.
