Rebel 16.2: Impressive!

...............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 .....

Well, what was happening seems not quite a miracle seeing SF lose a clearly won positon at move nr. 19 with Qe2? (=, Qc2+-) and even worse with 20.0-0-0? -+ .
20.Nd5, 20.Rd1, 20.Bg2 just to give 3 alternatives would still have had equal chances, probably one or two other one moves wouldn't have lost still, at least not as fast as SF's blunder here. And after 19.Qc2 instead of Qe2? it was a clearly +-, so SF gave away a win to a loss in just two moves, regards

Well, it is what it is. Fast game, Stockfish subjected to stress attack, can't find the best moves.

Not quite as bad as the one before but still the same as for CST "simply" profiting from SF- blunders. Here leastwise it was not only two, it was three blunders but again a till then won position of White's was ruined.

35.Rc2? gave away the +- that Nc3 would have had, yet there was still little advantage up to
37.a4?, again Nc3 there instead still would have had the edge for White. And then there came
38.Re3? and game over.
38.Ka2 instead was small advantage of Black's.
Of course such VSTC produces blunders from both sides normally, but these moves of SF's (always reaching depth 15, 16 only at these points) show simply bad lack of hardware- time, don't they?
Anyhow, it's not such a big achievement winning games by opponents faults only, again White had decisive advantage as long as no big blunders happened.

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.

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.

So CS Tal is coming then?

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 .....

Do you remember that game of CS Tal you posted in Selective Search, back in the 1990s? It beat Genius by putting its king on e2 and doing a (for then) unusual king-side attack?

Anyhow, it's not such a big achievement winning games by opponents faults only, again White had decisive advantage as long as no big blunders happened.

What it does show, is that even with depth (you say) of 15,16, there are exploitable holes in Stockfish algorithm to be taken advantage of, that SF is not the god it is made out to be. I'm working on it, finding spaces in the search tree where SF is blinded. You interpret that negatively for some reason. Me, I see it as an achievement.

Do you remember that game of CS Tal you posted in Selective Search, back in the 1990s? It beat Genius by putting its king on e2 and doing a (for then) unusual king-side attack?

Sorry, not. I didn't pay much attention to that and had zero control over what got posted in it. Maybe the game that Thorsten occasionally re-posts(?), was it an ICGA tournament where CSTal sacced the exchange, but I don't recollect anything specific about a king on e2.

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 .....

Well, what was happening seems not quite a miracle seeing SF lose a clearly won positon at move nr. 19 with Qe2? (=, Qc2+-) and even worse with 20.0-0-0? -+ .
20.Nd5, 20.Rd1, 20.Bg2 just to give 3 alternatives would still have had equal chances, probably one or two other one moves wouldn't have lost still, at least not as fast as SF's blunder here. And after 19.Qc2 instead of Qe2? it was a clearly +-, so SF gave away a win to a loss in just two moves, regards

What ?!

We are talking about the no.1 engine in the world of ~2 years ago.

Yes?

Go figure the blunders of the lesser engines of that period against SF and lost, did you ever see those posted?

The game is a beauty.

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.

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.

So CS Tal is coming then?

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 .....

I can vaguely remember the article, but not the game, probably Alzheimers or something. Yes, those sorts of king attacks were beyond the technology of the time, and a major big deal once got to work. I remember being endlessly put down because if it didn't win then it was useless, etc, etc. Also chess is tactics (they said), search was going to solve everything, all that counted was winning, etc. etc.
