Rebel 16.2: Impressive!

[Paul Bedrey]

Which hardware (cpu) do you use ?
Rebel works without any problems in arena.
Of course there are several arena versions.

I have a 4core Intel I7-8565U CPU.

I am able to run Rebel 14.1 avx2 in Arena 3.51. When I try to create Rebel 16.2 it doesn't work. It won't even display the engine config file. Only difference I see is that 14.1 is avx2 and Rebel 16.2 comes out a plain exe. I tried Arena autodetect in creating the engine but it still doesn't work. Maybe 16.2 exe is just avx.

I am using Rebel 16.2 in Fritz 18 and it works fine. I tried it in Arena 3.5.1, and I noticed it puts it as a Winboard engine, so you have to change it to UCI, but I am still having problems to get it to work. Furthermore, I don’t have much time to fiddle with it as work calls me.

Congrats to Ed/Chris for this venture. It's wicked fast, and I can finally use it for my own games & analysis. I always loved the old Rebel's and Tal's ways of playing. Combined looks promising. I understand about the Evalcorrect but what is the TC_Aggression parameter as it seems this is a way of increasing aggression too?

You need to be careful if you try adjusting that one. It's basically how aggressive the time control (TC) is at going to the edge, so to speak. Too much and you'll get forfeits. It's there because every net has different characteristics, and these can affect the time control algorithm, so - fine tuning purposes .....

Actually it's still there because it reflects the most recent tuning (and that was mostly TC), then I forget to take it out, is not really a enduser parameter, but there's nothing to stop you playing with them, but you will be on your own. Whoops! Just checked, it is a user param, courtesy of Ed who wanted it to remain.

I think "autodetect" might be a problem. Can you try to explicitly set it to UCI?

[mclane]

I don’t understand. Just put the path where it is and run it as UCI.

F11 and e.g. installation assistant

TC_Aggression currently isn't doing much, we used it to tune the time control.

That's correct, Arena notices the name REBEL and assumes winboard (likely because ProDeo was winboard). In the near future you will notice Arena does the same with Chess-System-Tal, it will show Rubbish of course Chess-System-Tal is UCI.

When it's ready. Meanwhile try this game for Tal Attack. I've not see a Stockfish so comprehensively smashed in so few moves without any idea of what was happening. Look at the evaluation discrepancies .....
