I guess you had to pay quite some thousands of dollars for participation in this tournament to the Kasparov organisation. Didn't you sign a contract to prevent them nailing you down in such a way? I've been on the internet since 93 now. First 4 years i had to do without timestamp from europe, so i simply didn't play. end of 97 i had internet on my PC. though there is timestamp, it's crucial for me to survive *any* level. At the world champs 99 internet, despite that i pay big bugs for several providers just to be able to internet quickly, didn't work during 2 days (sunday and saturday), or round 1 against Ferret and round 6 against Francesca. Of course the clock was stopped shortly, but not for many hours, so i had to play WITHOUT internet connection, and was lucky to have a small computer with me and was lucky for the organization to have a monitor for me. In dutch champs i was connected to the phone line and only for 15 minutes had a problem with xs4all.nl. xs4all.nl really has served me well over the years. All problems i ever had were not xs4all.nl related, but other ISPS. At the CCT tournament, played at the icc server, my problems were again huge. Whole europe had problems in fact. Just by starting games half an hour later, and one game when problems were biggest (i arrived 1 hour later at icc) lucky Junior had refused to play crafty. That was pure luck for me, as otherwise DIEP would not have played. Diep has played at 3 different machines for the icc tournament, with as absolute worste moment that i had to hand operate a machine from europe. After the icc tournament Sean discovered that the machine i was supposed to play on (dual xeon 550, and where diep didn't run a single game at) had a bad network cable, which caused all the disconnects. In paderborn for a few weeks at the IPCCC tournament i again used xs4all.nl, this time equipped with even more providers and passwords to find a route that wouldn't let me down. Still in game 2 against Shredder i was simply disconnected and couldn't connect to the crafty machine in not a single way. I was lucky to have a backup computer in Florida from Ahmad Altani, otherwise i would have had to resign the game or play at my P133 laptop with 16mb ram and windows NT on it (swap swap). The move i reconnected with was a direct blunder, caused by cleaned hashtables and a bunch of processors less. The problem wasn't in paderborn, but somewhere at i-p-d.nl. Overall, in europe i have had a lot of troubles connecting using internet. Actually i never have had a tournament without problems. Biggest were problems at the world champs. One biggest problems i had at the CCT tournament. A lot less problems at IPCCC2000 (though the average delay was like 10 seconds) and Dutch open ran near to smoothly. At home at the worst ISP of europe (but i don't need to pay for the phone then): casema.net, i usually have lot of delay and such, but less than i've had in the different tournaments, most definitely because a realtime connection is so much harder to maintain for hours than just internetting a few hours without probs. It's incredible that you paid all those dollars to play games using the internet against dudes that consider us enemey of the grandmaster state. Nevertheless i think your PR will be good.
