I hope this comes from the documentation of the joseki database. There the comment property in the sgf files is used to mark different types of moves and is interpreted by the joseki.c program which translates them to .db files. In those the "DO NOT MOVE HERE" patterns receive the N attribute (see e.g. pattern JK42 in kosumi.db), which after matching is converted to an antisuji move reason near the end of joseki_callback() in engine/shapes.c. Outside of the joseki database, antisuji moves are marked with the antisuji action, e.g. in pattern AS2 in patterns2.db Pattern AS2 ?XO don't play double hane at the edge XO. *.. --- :8,- ?XO XOa *b. --- ;!oplay_attack(*,a,a) && oplay_attack(*,a,b,b) >antisuji(*); As a further comment almost all antisuji patterns in patterns.db and patterns2.db are probably too general. /Gunnar _______________________________________________ gnugo-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnugo-devel
