The CM-64-6 personality (and game in which I drew The King)
Black was my CM-64-6 personality. That's CM9k with the book replaced with
"Depth 6" and the transposition table set to 64Mb. In other words, CM has to
rely on it's engine, The King, starting with the 4th move. It allowed this
draw by repetition. I could make the personality more realistic against
inferior players (like me) by setting the "contempt for draw" at, say, +1 to
keep the personality from drawing me as though I were its equal. I prefer to
keep the setting at zero though, because I use the personality as a study
aid. Keep in mind that the Alekhine personality lost to Christiansen because
CM-Alekhine has a high contempt for draws, according to John Merlino, and I
want CM to show me its best move even if it's a draw.
I created the personality as the fastest way to see how the program would
play positions I study. With Depth 6 as the opening book, the program won't
simply show me a memorized line for 20 moves in the opening I'm studying.
Sure beats watching the mentor lines window creep its way up to a reliably
high level. The personality lets me test moves against a grandmaster reply.
I recommend it as a study aid.
