The funny thing about MC scoring is that if white DOES win, then it doesn't matter what black plays, everything loses!
That would mean that in a scalability study, where colors are alternated, really strong versions of Mogo would score poorly against the weaker programs. In a serious competition you would want to throttle down the playing strength (when playing black) so that it could win more and not just quit (resign) out of frustration! I wonder if we are seeing just enough of this that it's causing mogo to get worse results as it gets stronger? It seems unlikely - but when a position is in reality losing, and the score drops, mogo tries lines of play that in theory maximize it's chances of still winning anyway. I wonder if these "desperate" moves are actually hurting it's chances of winning? You will see something like this happen with really simple MC programs that do not have tree's. You will see the score drop and it will play a really weak move that wins if the opponent completely overlooks a simply threat. What MC doesn't understand is what good players know, that risk has to be managed carefully - you can't just lash out like a wounded animal. Often "normal" play will give the opponent some chance to make an error you can take advantage of. - Don David Fotland wrote: > If Don's data shows that after E5 C5, white will win, then if mogo is good > enough, it will see that it can't win, so it will play it's second move to > create complications, which C6 does.
