The /2 with color-swaps would work fine with librarys that don't store the whole gamestate, but I doubt it's worth implementing it in fuseki-librarys: Since there are usually no or very few captures during the fuseki, the player whos turn it is is determined by the gamestate itsself: Black if both colors have the same number of stones on the board, white if it differs. This means that "color reflected" positions can only occur if there was a capture or if you don't rely on the whole gamestate (eg. pattern-librarys, fuseki-librarys that allow "?" fields that are undetermined). eph _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
