We were discussing Zillions. And Zillions works exactly as I decribed. Even Humans think far deeper than 4 ply; without that it is not possible to play any decent Chess, except perhaps at the level of a 6-year-old. But my main criticism still stands, and is totally independent of any mode of move productions: you admire moves that are futile, and call them 'a plan'. While in fact they are just bad Chess, by an entity that does not properly know what it is doing. You loath 'bean counters' for no apparent reason other than that they play good Chess. Well, for deriving piece values I need Chess of a reasonable quality, and the better the engine, the faster it can play to deliver that quality. If Zillions needs 30 min per game to reach the same quality as Fairy-Max has at 1 min per game, a 400-game run that I do in a day with Fairy-Max would take a month with Zillions. That is not doable, as you need mny such runs to derive the value of a single piece. The 3 Guanacas beat 2 Knights by 54.8%. Again spectacularly little better than 3 Alpacas. The small difference between these pieces continues to amaze me. I should do more tests with divergent pieces, to see if this is a general trait of non-capture slider moves. 2 Alpaca vs 2 Llamas ended at 50.6%. I forgot for whom, but that does not really matter as this is equality to far within the resolution of the test. I will stop this testing now for some time, as I have to test the opening book for my engine HaQiKi D, to get it ready in time for the Computer Olympiad in Pamplona (May 10-18).
