open source battle Ivanhoe v Stockfish at long time control

Not sure why stockfish let itself run out of time here just before making the 1st control---even with the extra 1/10 second "overstep" margin. It looks even so I guess this will need to be changed into a draw when figuring the final match results.

Standings after game 6

Ivanhoe 3.0 + 2 = 2 - 2
Stockfish 3.0 + 2 = 2 - 2

I think this is a very interesting match you are running, and I am watching the results. It doesn't have to be the strongest IvanHoe 9.46h version to be worthwhile and important. Thank you for running this match. I know it takes a lot of time and patience at these controls.

The Very Best To You,

george

Good luck with running Stockfish. I had problems with it on TC so not testing it until it can be fixed.

Best,
Gerold.

Thanks George.

I was looking forward to the games but Stockfish is losing too many on time. I think I will need to stop the match and see if I can find a "fixed" version. It does not make sense to continue if I have to adjudicate too many games because of time losses.

Take care

Hi Gerold.

I was not going to "blame" the program, because maybe it could be something here. But since you (and now I have read others) are having the same issue, I guess it is a problem with Stockfish. I see some supposed "fix" available so maybe I will try some fast matches with it. If it can play blitz without overstepping the time then maybe I will start another match. They seemed pretty even so far, though I know nothing can be said from so few games.

Take care

Sorry that I did not know of the time-loss issue with Stockfish before starting this match. I did not mean to waste your time! This seemed like it would be a closely-fought match, with many good games.

Due to the time-losses by Stockfish, I am aborting the match here. It does not seem to make sense for me to have to adjudicate many games over a maybe 100-game match. Maybe I will do another match between these two if I find a version that does not overstep the time-control. I see some postings about a possible fix; I will look into it further.

Are you sure your specs don't have a typo? What is the 30 min. 10sec. per move. I don't really, I admit, keep up much with controls that long, but that I have never heard of.

Counting the 200 games for 2.2.2 I am posting shortly, I have run 450 40/3 repeating- with no time losses. The only ones I ever get are in fischer controls- and I will never run even 1 game again with incremental controls.

In your case, on the time losses, if SF was up 3.00 or more at the time it lost- adj it as a win for SF. Under 1.00- adj it as a draw. Down 3.00 or more- call it a loss. Replay the ones in between. It's manageable to work around- but a pain in the ass I know. It's what I would do probably before I would throw them out. There won't be any errors in your adjudications. It's tough to deal with- I have pulled my hair out at times.

Hang in there- you are doing good work.

Best,

Hi George

The time control was the first 40 moves in 120 min, then the second 20 in 60 min, then the remainder of the moves in 30 min plus 10 seconds per move. So basically 3 minutes per move over the first 60 and then 30 minutes for the rest of the game, with the 10 seconds given to avoid time-loss.

I think that the "fixed" JA version of Stockfish does not have the time-loss issue. I am running a game-in-10 seconds match now to verify this. If all goes well (so far no time losses by Stockfish) I will restart the match with this new version.

Take care
