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.

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.

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 to 5/8 because there is definitely something wrong with the TC even with the JA build in 3/3 and 4/4. It runs out of time and just is moving in emergency. This means that sometimes it will start with a positive value for the color and then move so fast that it ends up in a draw or a time loss.

If someone has better TC values I can try please post them.\

I've been doing a 4/4 tournament (4 minutes, 4 second increment) with JA, Gran2h/k, Gran2i and Gran2j. I only have 180 games or so, but I don't think there is any reason to believe that any of these builds is stronger than the other at LTC.

I haven't checked the games yet for TC problems. My principle concern, though, was that our changes could negatively impact overall engine performance. This doesn't seem to be the case.

Jeremy I'll try and pick out some of the games with time problems. From what I've seen though the problems are the same for the GTB variants and the 201 JA. It looks like towards the end of some games they all have to start making emergency moves when they are down to seconds. This seems to happen fairly often. Look at the endgames and you will see only a 1 instead of xs where x is a number of seconds.

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

What are your time controls? I'm current running 5"+8' increment round robin with your top 5 engines. I get slightly different results. Will post when I get 200 games.

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.
