If comments (legal and not) are a problem, first use trim (part of 40H).

4. Since a King is allowed to castle with each of the rooks on its flanks, why shouldn't the King be allowed to castle with a King pawn promoted to a rook? (assuming it meets the usual requirements of not being in check, not passing through check, etc)

The list of killed engines was introduced about a month ago :) The total number of games killed is currently about 2,200 We try to ensure all engines on the list get at least 200 games. If a new engine version comes out quickly, and the old version only has a small number of games, then either we c...

Hi Graham, Is the list of "killed engines" something new? I didn't see it before, but that doesn't mean anything. Anyway, I think it is a good idea to prune games that cause statistical "noise", such as these. But isn't "kill" a bit harsh? http://www.computerchess.org.uk/ccrl/4040/kill_list.html But...

The butler did it!

Hi Graham, I am not sure if I understand correctly the term that the engine "crashed". Please understand my somewhat naive questions. When the engine crashed, does it stop thinking, no outputs, and the OS pops-up an error window? Or it simply losses on time while thinking indefinitely on a position...

Imho, I think the chances of unassembling Rybka code is much, much less than the chances that one of Vas' computers got hacked.

I don't know why Vas is laughing about it. Perhaps that's just for public consumption. But if it is a clone (I'm neutral on this), then there would have had to have been a breach in security. Vas should be concerned about that possibility to avoid a replication. He probably is.
