I've noticed something weird at fixed depth, for instance:

.17/29 0:00 -2.63 35...Bd3 36.e6 Bxf5 37.e7 Rfb8 38.Rb4 Bd7 39.Rf4 Kh7
18/10 0:01 -2.52-- 35...Bd3 36.e6 Bxf5 37.e7 Rfb8 38.Bc4 Bd7 39.Bb5
18/10 0:01 -2.41-- 35...Bd3 36.e6 fxe6 37.fxe6 Rf1+ 38.Kh2 Kf8 39.Rxb7
18/10 0:01 -2.19-- 35 ...

Here are some partial results. TC=5/8 Ponder=off hash=1024 I changed the TC on R4.1 and on Gran2h. I will post them when I finish the tour. Very few time losses.

Jeremy, here are a few games with the time problems I mentioned.

Ok, I think that 2h is the best of the lot. It seems to analyse without bouncing all over the place and the only fault I can see is that in the opening it will over evaluate the position. Once it gets into the middlegame it usually gets back to about the evals of the best engines. I am going to go ...

another 60 games only one time forfeit by 2h. I think it's just because my TB's are on a Sata disc.
h and g are pretty much even.

Here is a partial run. 4/4 TC Ponder=off Sleeping threads=on 1024 hash i7980@3.2
Pgn attached at the bottom. Some time losses to all programs. But only a few. OK a bit of a problem on the pgn it's too big and I'll have to edit it later today.

Some results (note that Gran2k is exactly the same as Gran2h):

And here's another one with a slightly different strategy. I'd be interested if you see time losses with it, as well (also with ProbeOnlyAtRoot disabled).

Thanks so much,

Jeremy here are the 60 games from last night. Only 1 time loss and it was for 2d. Surprise black won more games. Ponder ...
