Hi Paulo!

Yes, cool queensac and a good testposition too, for the computers I mean! I think it is mostly a question of depth, because in the line that Rainbow Serpent saw, White gets an endgame where Black still has a passed pawn but it can not ever promote, bishop is guarding the promotion square and Black does not have pieces anymore, other than the King :) And on the other side of the board, White has no passed pawn but two connected pawns which are much stronger than the lone black pawn on the h-file. But there is no clear evaluation rule for that pair of pawns, it depends on how much support/interference there is from other pieces too, so it has to be searched and that would require just some extra depth.

I have seen that move ...c3 in deeper lines too, further along the PV I mean, but there it dropped in score after a while. But if you see a good line please post! It does not have to be a Houdini line, because I think the endgame should not be too difficult that you need Houdini's extra endgame knowledge for it. Just its extra depth 8-)

I will try to make a new verson of Rainbow Serpent that might be able to look just a little bit deeper, then I will post again, it should be possible to get an evaluation a little bit better than +0.16 I think. Watch out Houdini 8-)

Tommy Cooper engine in the making regards,
Eelco

I analyzed with Hiarcs 13.2 and with Stockfish 2.01, Eelco. Stockfish
is very good at positions that have deep depth. Tord has spoken about
this. I tried to find a draw but I could not.
My curiosity is whether the final position of the output of Houdini,
sent by Martin, is won for white. I intuitively and based on quick analysis
I did with SF, I think that White wins.

Paulo, the problem with that long line of Houdini's is that it is bound to be full of weaker moves deeper into the variation. For example, if you move half way through the variation and let Houdini analyze from there, Houdini will not agree with some of the suggest moves. It will improve/refute it's own line This is why it is better to move the pieces and allow the position to develop. But from the original position you are correct, white wins :wink:
