It seems to be a badly flawed design if it does, because I'd like to think that a learner would protect a program from playing the same opening round three that it played in round 1 and lost. And the last time I played in a human tournament with Crafty, I had to alternate colors after *every* game. As a general rule, on the chess servers, this is also common practice. That's obviously fixable... >>>Now, go figure if this is the fault of that autoplayer or if it >>>is rather a design flaw of Rebel s learner. >> >>Come on! >> >>Who is not sticking to the general accepted auto232 rules here? >> >>And I should be responsible for that? >> >>This is the world up-side-down, no? > >No. No one says games must be played all black first and then all white.
