Currently playing round 2, although I don't see the pairings. Round 1 results are here: http://www.computerschaak.nl/
Arasan is playing thanks to Richard Pijl, who offered to have his daughter operate Arasan via network to my local server.

The Baron is the winner
The Baron by Richard Pijl has won the tournament:
http://www.computerschaak.nl/pt46-round-1.
Congrats to Richard! Dirty came in 2nd.
Arasan finished 4th, behind Rookie. Generally it did ok but mysteriously dropped a Rook in the 2nd round game against DBP/PuppetMaster - not sure what happened there.

I don't think so. The bad move is .. Rd2 here:Dr.Wael Deeb wrote:

I cannot reproduce this. I am wondering actually if Rd2 was transmitted to the opponent instead of Rd7 (the tournament is not automated but requires a human operator). Rd7 is maybe not the best move but is ok. However when I tried an offline search Arasan seems to prefer Bf3 in this position. Game follows.

Yes, that seems to be correct. I don't know what page I was looking at but it was evidently not the final standings.

I do a quick check through all of the 1000+ games that are played on my computers each week and I've never seen Arasan play such an obvious blunder.

Re: The Baron is the winner
I was not watching that game, as I had to play my own, but this is what they told me later:jdart wrote:Arasan finished 4th, behind Rookie. Generally it did ok but mysteriously dropped a Rook in the 2nd round game against DBP/PuppetMaster - not sure what happened there.
Arena is what happened! It mysteriously removed a Queen from the position somewhere during the game, and so probably was feeding Arasan nonsense positions. (Arasan was running as remote engine through ssh on a Linux machine, under Arena, which was running locally on the laptop. In the game of Arasan against Spartacus also a Queen suddenly disappeared when it was moved, but there we noticed it immediately, and could recover the situation through takebacks before any damage was done.)

Re: The Baron is the winner
That is certainly strange! Arena 3.0 (with a non-remote engine) has been pretty reliable for me. I tried to use Winboard but as reported in the Winboard forum, I could not get it to work with a remote engine through a ssh connection. Maybe it is possible but I ran out of time and had to give up.
