Because it had winning chances with >a piece down? CSTal knew it had the draw. It had Qe1+ in its main line with a draw score, and Virtual was showing 0,0 as main line score. This was a great game, I turned up on around move 25 or so; and CSTal was in a terrible cramped position after the opening; Thorsten was sulking, the Virtual operator was looking very happy; but although we were showing main line evals of -1 and -2, I was happy. Virtual's eval was heavily interested in the centre control, Virtual had pawn break possibilities in the centre; but to mobilise the centre advantage it was clear that Virtual was (a) going to be playing f4 (horribly king weakening, but centre controlling; and (b) the obvious Virtual centre break allowing rook counterplay on the queenside. CSTal didn't have much to do, but maneouvred its queen onto the kingside. So slowly the game resolved in this this way, Virtual preferred centre control to its king safety and CSTal of course took the opposite view. then it was queen right into the Virtual open king position, and draw by check-check-check. Except CSTal was now feeling so pleased with itself (me too, and the Virtual guys were looking very glum, and Thorsten jumping up and down like a man possessed), that it suddenly overrode its draw move Qe1, switched moves and blew the game. We have no idea why it switched, its mainline was overwritten by the move being immediately played, and Thorsten couldn't get the move to repeat when later tested. The draw was the obvious thing to do, other programs also make Qe1+ 0.0 as best move. CSTal has played real nice to get itself out of trouble. Virtual was a good scalp. I wanted the draw, CSTal would have been high in the rankings 6.5 out of 10 with one round to go. Oh shit, basically. > >Was the game of Junior already finished? Nope, still in progress.
