I did not want to critisize Arasan (or Baron). It just happened, that I followed the game, and saw the score going to drawish and then to winning score for Baron again. Then I downloaded the game, and had a look at the end where this happened. >In the 2nd position, Arasan switches and sticks to Kc3 >after about 16 seconds with or without tablebases, and >gives a zero score after 45 seconds (I only have 5-man >tablebases). I think, 6-men TBs cannot help here. 5-men do (especially KPPKR). The 6 men positions that will arise in search, should be easy to evaluate (either white wins a pawn, or somebody blundered in the way, or - the interesting ones - immediate recapture, which yields in a 5-men pos). > But it didn't have 16 seconds in this game. No doubt, under the game conditions, this was difficult to find. Even more difficult to find will be, that Kc3 really is much better than the rest (takes a *long* time for my engine, when I search for the second best move, to see a good score for white without TBs). >The 1st position (find Rb6) is a lot harder for Arasan. Without TBs, Yace needs about 10 minutes to find Rb6 (0.01 score ...) and ~100 minutes to see a score > 2 (Shredder Paderborn finds Rb6 on my computer in about 90 minutes, and still shows only +0.39 after 250 minutes). The analysis of Baron, that Richard just posted is much faster. Regards, Dieter
