I know Rd2 is dubious, but that was never the point of my post. No need to lecture chess to me (well not tooo much), I had 2300 fide rating some (ok many) years ago you know :-) > >Let me summarize your interest and the analyses this way.

That this move is odd is not so much a question of the "later" >position you gave us. Rd2 could be shown wrong in the position it was played, I What? You are proposing I should have pruned out Rd2 at ply 1 using general principles? For a human that is possible, but if you try to do that with a program you will have a disaster! Your comments seem to indicate a lack of understanding about how a chess program chooses a move?! There is a big difference between being able to say, as a chess player, 'this move is bad because of X, Y, and Z' and knowing what to change in a program to avoid such moves. My judgement is that most of the bad moves played by Warp vs Brutus were caused by poor static evaluation of the centralised white king (this position is just one example), therefore it did not have enough incentive to castle. I don't see any reason to change my judgement. cheers, Peter >would pretend. Simply because White hasn't o-o yet. Also because bNe4 is always >a direct attack against the R.
