Congratulations on your top 10 finish

I am sure a few more will join - due to the very short notice of the event sadly Hiarcs will not be there. However we hope to be back in Leiden later in the year and it would be nice to go to China in 2008.

Best Wishes,

Harvey

It's interesting if you check out the past winners: http://en.wikipedia.org/wiki/World_Comp ... ampionship

Junior and Shredder are clearly dominant. People will talk about other engines being stronger etc etc but the authors of these progs perhaps are better at configuring their opening books against their opponents for a one off game?

Junior and Shredder are also entertaining programs so I'm glad they have a good history!

I wonder why micromax plays
Is it better than Joker?

Note that I saw that in their last game micromax got a winning advantage against Joker and it seems that it simply lost on time.

Yes, that was a shameful display by Joker, and is one of the reasons it doesn't play. I suspect there is an ilusive bug somewhere in Joker, because in that game it completely voluntarily gave the exchange in an extremely obvious way. (It put a Rook that could have gone anywhere and didn't have to be played at all on the same diagonal as his other Rook, where they were immediately pinned down on each other by a Bishop, with only a single intervening check as possible delaying move, so a 5-ply search should have seen that, while it was reporting 13 ply.)

The only reason uMax lost that game was that I was operating uMax, and I am a lousy operator. I let the time slip by talking too much with others rather than paying attention to when uMax moved. (Unlike my laptop, the desktop I brought did not make an audible sound when it moved.) I was playing under Winboard, and could not think of a way to bring the time on the Winboard clock in accordance with that on the official clock, as the 'save game' menu item of Winboard_x seems buggy. By the time I had discovered that the game history was accessible in another window, so that I could copy-paste it into a newly started Winboard set with another time control, there was only 4 min left on the clock, and it was physically impossible to do perform the moves fast enough to prevent forfeiting on time. Due to the very uneven time distribution uMax had by that time probably missed the winning line anyway. Shame on Joker. Shame on me. Too bad for uMax.

On the average Joker still tests ~300 ELO stronger than uMax, though. But Joker is still just one not-so-good engine amongst hundreds of similar ones. Micro-Max, on the other hand, is unique because it is the World's smallest chess program, and by a very large margin the only program that has more ELO points than characters of source code. Due to this special status I thought it would have more right to appear in a WCCC then uMax. The organizers more or less agreed with this reasoning, so I entered uMax. Both engines would almost certainly lose all their games anyway, but at least uMax has a good excuse!

I might still have time to make it SMP...

No idea whether the Sleep In still exist, but no need to take an expensive hotel. There are nice camping sites near by.
Come on guys, take a week off, register and come to Amsterdam and lets have a huge computer chess party.

Cheers,

Hi Gerd,

I did not know that Fruit plus 2 Fruit derivates are allowed in
a WCC event?

You probably misunderstood, there is only one new entry, Gridchess, which is based on Crafty, Fruit, and Toga:

GridChess is composed of two major components: 1) The proxy chess engine (Crafty based) performs no tree search itself but has some kind of a master role to control the optimistic pondering with distributed worker clients. As a simplified explanation of optimistic pondering here, one can imagine the worker clients forming a pondering pipeline with expected opponent moves extracting this information from the principal variations provided by the chess engines. 2) Real chess engines (controlled by distributed worker clients), Fruit/Toga based, parallelized with Young Brothers Wait Concept (YBWC). This way a combination of two parallel concepts was realized building the complete GridChess system: The parallel Fruit/Toga base engines using the YBWC may run on high performance clusters, each cluster representing a worker client for the proxy chess engine. Several such clusters are then used for an asynchronous distributed game-tree search with the optimistic pondering method.
