So SmarThink and Yace have a weakness in their time management. At longer >time controls, this weakness is covered up. Time management is not the strong point of ruffian. Try it at 10000 moves/100 minutes and you are going to find that it does not use its time. I think thst Ruffian is clearly better than Yace at long time control and the result of Leo tournament proves it. Uri > >The same thing happens for all kinds of weaknesses.

There are weakness that are not important in 1 minute/game but are important at longer time control. This is why you often hear programmers >saying that their engine "performs better at longer time controls", or how >"<insert engine here> is very strong at longer time controls." I do not hear often programmers say it. > >It isn't really stronger. Rather, fewer of its weaknesses are being exposed. also fewer weaknesses of the opponent are exposed so it is not a reason to perform better at longer time control. Uri
