Personally, I use the terminology in much the same way as Heikki. I use the word "mistake" to describe (for example) a move that loses a large group, but does not change the game from a win to a loss. It makes sense to me to generally apply "mistake" to any move that loses points relative to the best move on the board. The term "blunder" means, essentially, a move that lost the game. It can be quite difficult, of course, to determine unambiguously whether or not a particular move is a blunder. In an otherwise close match, a large mistake (i.e., loses many points) is probably a blunder. Toward the end of a close game, it may be possible to find unambiguous blunders, and some of these could be single point mistakes.

Between equally strong players, a one point mistake can be a blunder, if it was late in the yose, and the game was won by half a point. On the other hand, throwing away a 20-stone group may not be a blunder if you were already going to loose by 100 points. It could even be a (mis?)calculated risk, ignoring a threatening move in order to get an attack on an even larger group, even if that attack later turns out not to work... Just my uninformed gut feeling, of course. -H -- Heikki Levanto "In Murphy We Turst" heikki (at) lsd (dot) dk _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
