If a human thinks they've got serious drawing chances, they'd never assign a score of +2. +2 should indicate a decisive advantage. DJ6 has been giving +1 to some (but not all) of these endings that I've been coming up with, but my comments like "and White should be able to grovel a draw" are based upon my own, weak expert assessment. I haven't been able to check every line (who can?) but I am coming around to the view that DT2 was able to find +2 back at ...c5. I do also think that the score is not completely deserved (e.g. that crafty and DT2 are overassessing Black's advantage in some of the endgames). And it's clear that no, DT2 isn't winning a piece. So everybody has something to be happy about. :-) Dave
