I considered this too. It should be obvious that black has a good advantage in all these lines, so certainly a good score is warranted in addition to the pluspawn. That doesn't have to mean it forcedly wins. I know it isn't much to go on, but if I let a pair of programs dug it out from most of these lines black wins without too much trouble. >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.

So everybody has something to be happy about. :-) True. I'd like to see anyone produce c5 even with a -1 score in 7 seconds though. -- GCP
