This is an engine that shows 2. c4 on its own? I find it a bit hard to believe. Never seen that before, it would seem very hard to find. A nameless engine that you have on your computer Dann?

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

improve move ordering. :) reductions do that because reduced-depth searches utilize the hash move from earlier (probably deeper) searches which works out well. And don't test on tactical positions, those are "worst-case" because the very idea of a tactical position is one where the key move is some sort of "surprise" and surprises break move ordering pretty badly, obviously...

Doesn't surprise me. I have had previous versions of Cray Blitz or Crafty that would play the Ruy and have a very accurate variation. Ditto for d4 which Cray Blitz played on its own and it would play d4/c4 in the starting variation. Earlier versions would puke up the 3-knights including white's Ng5 (but no fried liver follow-up however). And some have liked e3 as the first move. So long as they pick a reasonable first move, one should be happy. If a program pukes up 1. g4 or 1. f3 and 2. Kf2 I might be a bit concerned. :)

Thanks for posting your examples Dann! I still think it is pretty unique to see c4 even if Cray Blitz already could do that a long time before Ivanhoe. I suppose you could write some special rules for a program to play it but this is just with the general search. I don't think Rybka would play it, because it also has a habit of placing Knights in front of pawns, and I do believe there was a discussion at the time that Larry was still tweaking the eval of Rybka, that he could not get the engine to play c4, not without hurting elo I suppose.

It is a pity there are no real supercomputer chess-programs like Cray Blitz active anymore, it would be fun to compare programs on such big hardware with machines that almost everyone can buy these days. Maybe the large number of processors in the big mainframes used for floating point simulations, can not really be effectively programmed to play chess. The transposition tables play such a big role in search efficiency and building up the search trees.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
