If you reread my comment, you wil notice I said that endings is the "weaker" side of Rebel, not "weak". Hiarcs and Genius are the only two programs I know that have stronger endings than Rebel. In my opinion, Rebel excels in the middlegame, not in the endgame. > I don't have enough games to come to that conclusion >about Rebel 10. Would Hiarc 7 being so strong in the endgame win playing the >other side of the end game in its games with Rebel 10? I didn't try, but I am sure it would. Some of these endings were a dead draw, even with symmetrical pawns. Today I'll send the games to Steve and you can check this yourself. >>- Fritz 5 simply didn't have a chance and was outplayed by H7b in all phases of >>the game.

The result might be reversed in 10 more games, at least in theory. Watching the games gives you a very different impression, though. >>- Junior 5 was the tough cookie for H7b.

Happens ALL the time. A beats B, B beats C, C beats A. This is one of the reasons that makes so important to play as many different opponents as possible. > It can be very hard to get a good read on chess programs >from a small sample. I agree. Particularly if you take into consideration only a match between two programs. That's why I intend to include in my tournament all the new versions that are coming now. We'll see what happens in the end. Still, >60% after 30 games against the very best is at least an indication that H7 seems to be very strong, don't you think?
