I can't imagine a company like IBM putting a crappy version of their image program for public consumption. It doesn't fit because such a thing would damage the image they build beating Kasparov. >And putting such nonsense on Ed's web page is _highly_ misleading. > >To say the least. > >Bob Deep Blue Junior is connected to the Internet in the hall of the museum near to the tournament place of the 9th WCCC. You can play any time control and we set Deep Blue Jr. to 5 minutes blitz and Rebel to 10 minutes blitz. Rebel played on my laptop of 333 Mhz. It was surprisingly to see that in the end Deep Blue Jr. used about the same amount of time as Rebel for the games. On the day before Chess Tiger played 2 games against Deep Blue Jr. but then the machine played indeed on a 1 second per move level which apparently is the default setting. Tiger won the first and lost the second game but the game scores unfortunately were lost. Tiger played on a Pentium 150 notebook. Christophe plans to play a few more games today against the monster but I wonder if there is any time left for that as today we have to play the last round, the blitz tournament and then move to the closing dinner. I heard some rumors the blitz tournament will not take place because the impossibility of some participants to move from one place to another which would be a too big advantage for that team. But you never know for sure in ICCA tournaments as things can change very easily by hour. I really loved the initial programmers meeting before the tournament. When the issue of accelerated paring for the first rounds was discussed the ICCA asked for a voting by all present participants and the majority (90%) voted for a normal Swiss tournament which was accepted by the ICCA. Head off for Jaap, Tony and David! As to the games Rebel played against Deep Blue Jr. I was shocked as Rebel beat the monster on his own specialty namely tactics. Also the machine played some horrible positional chess at times. If this is not the real thing IBM better can put it off. Here are the games. See for yourself.

Nxf7 1-0 Here the game was interrupted and Deep Blue Jr. refused to play any further whatever we tried. We also were unable to figure out how to play with the black pieces so Rebel only played the white pieces in all 3 games.
