Hi Oliver,

I'm looking forward to trying out your new version very soon.

Cheers, Graham.

Hi Oliver,

I'm looking forward to trying out your new version very soon.

Cheers, Graham.

Hi Graham,
I am happy you are looking forward to it.
But you have still have to consider two issues:

1) I never found the error that occured on your matches, because it never occured here, neither on any other tournament that was played. This means, it could still happen.

2) OliThink is still quite weak in endgames as the eval is just mobility. Tt has absolutly no plan about engame strategies.
So sometimes it still throws away a win or draw. A typical situation is when the King must go to the other side of the board but this is beyond the seek horizon.

I'll let you know if I find any problems Oliver.
OliThink will play in my "Rise Of The Colossus" tournament:

Very nice Oliver! I hope that you will request Olithink to play in Olivier Deville's next open war tournament. Engines play by author request only.

Okay, now I am curious, so I am playing a 100 game 1+1 TC match using the sherwin50.pgn. I will report when it is done.

Very nice Oliver! I hope that you will request Olithink to play in Olivier Deville's next open war tournament. Engines play by author request only.

I think it is playing right now in division E. It snatched 1/2 a point from LearningLemming in the first round (and LearningLemming was hard pressed to get the draw) but has not done as well in subsequent rounds.

Oliver is claiming a big strength increase for 5.1.6 and it is 5.1.4 that is playing in Olivier's division E tourney. Maybe Olivier should restart his div. E tourney with the new OliThink!

Romi - Oli, so far 20.5/33 +19 -11 =3

RomiChess96c - OliThink : 63.5/100 56-29-15 (1110011000=110111011011010=11=011100111101=1101010011111==10011=11=1=000111100=1=1=111101==111=00110) 64% +100

I will run OliThink against the last released version of RomiChess (P3k) to get a further comparison. So far RomiChess96c is testing about CCRL 2650 ELO, but I seriously doubt that it is that strong. RomiChessP3k is CCRL rated about ELO 2507. When this next match is finished we should know more.

I dont think this is fair. I think due to our testing at 1min+1sec only, Romi is ultra optimized for that time control.
