But I have a feeling that when the lines of communication are open, and one has the will, then good things can result. Stay tuned. LambChop has made a move, due (I hear) to the changing of lazy eval and some other things. It's threatening to jump to the 2500 level soon. Otherwise, the list order was pretty much unchanged from last week. New highs were recorded by Zchess (2598) and TDChess (2670). Those guys are pushing the envelope, no doubt about it. TDChess played 488 games to take the games-played award. Some of the ratings are remarkably stable. For example, if you discard LambChop (for stat purposes), the mean rating change was only about 20 points, while the avg games-played was around 100. Considering that one can lose or gain up to 30 points per game, I think that indicates the ratings we have here are pretty much indicative of the relative strengths of the programs (for their choice of opponent and time- control). Your mileage may vary, but the point is that the list is taking on a recognizable and stable form. SSEChessII has been moved to the inactive list. OilThink has been removed entirely, since it hasn't played in a few months. If anyone knows what Oliver is up to, let me know. New Feature I thought I'd post a position each week, taken from member submissions from the current week's play. Recently on the CCC board we've had a few positions posted, and these have helped me track down some problems with my code. Probably just chance, but I think these things are helpful for programmers in that they can see how their results differ from others, and figure out why. So members, please send me interesting games that your programs play (or just the positions), and perhaps we can all benefit from the analyses. To start the ball rolling, here's a position from the game Amateur-LambChop, played on ICC yesterday. For some reason, Amateur declined the easy move, which would have won quickly, and played a tricky move that led to a loss. On subsequent analysis, it took Amateur 9 ply to see the right move. During the actual game (blitz), it only searched about 7 ply. I'm thinking this might be some bug or other weirdness. Does your program have any trouble finding the right move quickly? 7k/2pn1Q2/2r4p/p1qpp3/Pp1b3N/1P1P2PP/2P1R2B/7K w - -
