The list is the top 20 only Junior 7 has the same number. 23 Junior 7 : 2576 30 23 528 50.1 % 2575 28.6 % Although you would also expect Junior 8's number to be very close but in this case that hasn't happened. I remember during beta testing one of the Tiger's Jim Walker and I commented on this fact regarding Junior 7. I think Gambit Agressive plays to win and sometimes this results in a loss sometimes a win, maybe against humans this trying to win would result in a higher rating than the default. Also if you look at both Tiger 15 and 14 the draw percentage is very close. >It looks like the strong speculative programs are the ones with a low draw >percentage. It was expected, somehow, but it is always very interesting to have >a confirmation by numbers. I would say I'd agree with that, probably similar even with Human chess. Sarah.
