Sjaak randomises its initial move order at the root (in the same way as Nebiyu apparently).

Re: Thermopylay Marathon 2011 (live!)

Sjaak has exactly the same bug as Catalyst. It also does not count the forced moves. Can you fix that, Evert? Or would it be better if we just abandon the idea of playing from a different position in the second cycle? Most engines randomize, I think. At the moment I don't have a clue where to start...

Re: Thermopylay Marathon 2011 (live!)

I agree. 8x handicap is better because with the longer time control Nebiyu & spartacus are less bound to make tactical mistakes due to time trouble. I would say place 3-6 is up for grabs and with 8x handicap they might join the the top. Who knows with the new catalyst too? ChessV actually beat Nebi...

Re: Thermopylay Marathon 2011 (live!)

Probably due to very high mobility score. It likes to bring out the captains and leutenants very early +2. Catalyst also seems to have differing scores than the rest of the engines. My guess is different piece values. Almost all disagree with passed pawn evals. Quite possibly. It doesn't really mat...

Re: Thermopylay Marathon 2011 (live!)

I noticed that Spartacus seems to give the Spartans more than +2 in the initial position. Is that deliberate?

By the way, the first game between Sjaak and Spartacus has a nice example of hoplite vs. wrong bishop.

Re: Thermopylay Marathon 2011 (live!)

Ok. Well, I'll see if I have time to test and send on an update. If I don't, that's just too bad.

Re: Thermopylay Marathon 2011 (live!)

In principle I wanted to allow updates only at the end of a complete cycle. But on the other hand, I don't want to discourage people improving their engines. But hasty updates within a tournament are a recipe for trouble. All versions playing now have been extensively tested for not being buggy, (w...

Re: Thermopylae Marathon 2011 (live!)

Sjaak vs. Oberon was a very interesting game. At some point Oberon allows Sjaak to promote to a second Queen, so that for more than 50 moves it is facing two Queens (+ two Rooks + Knight). The heavier pieces of the Persians turn out to be quite powerless against the lighter Spartan pieces, which de...

Well, yes, but only because there are 12 s++; lines in the example you posted there.

Re: Getting ready for Thermopylae

Fortress draws are simply cases where the strong side can make no progress, without an obvious reason, such as being perpetually checked or losing a piece. I know. What I meant was, I dnn't understand how the described fortress draw for king vs. king with nightrider and ferz works. Probably trying ...
