Most aggressive Whittington / Schroeder

[swami]

I'm doing work on a quantitative "aggression test". It involves beating a 2100 FIDE Elo engine in certain positions and shows an engine's tendencies towards king attacks. It doesn't test for strength.

What is the most aggressive chess engine out there, over 2700 elo? I was wondering if Ed & Chris had cooked something up in this department...is the new CS_Tal still private for instance?

In my experience, it's without doubt "OpenTal", based on engine named Rodent.

bit late to the party, not long ago I tested HIARCS14 at 1600 elo (around 1900 FIDE) versus various engines. Was curious to see which engine can manage to checkmate the fastest i.e which engine goes "straight for the throat" against non-perfect play response. I made them play thousands of bullet games, some tests done without opening book and others using gambit opening suite. I still cannot say that I have come to any particular conclusion, mainly because I don't know how big the correlation between "most aggressive" and engine prioritizing heavy attacks on opponent king is. But according to the statistics these engines scored the best:

1. DisasterArea-1.65 (tweaked parameters)
2. rodent-IV - (Suicidal Gambit personality)
3. opental 1.1
4. Wasp 4.5 (tweaked parameters)
5. spark 1.0 (tweaked parameters)
6. Zappa Mexico II (tweaked parameters)
7. ShashChess24 - (HighTal personality)
8. Pedone 3.0
9. Wasp 6.0
10. Rebel-14.1.2 CSTal
...
42. ChessMind_082

if anyone is interested I will post full .pgn database and statistics as well as the overall EAS score.

P.S I can provide download links to the engine and parameters used for anyone interested too..
P.P.S I'd love to see if Mr.Pohl is interested to test these engines

Nice list. What are the values for the "tweaked personalities", is that available anywhere?

Ofcourse I am interested in the full list, if you already have it. Thanks!

[swami]

It would be interesting to test against the couple of
standard chess engines that's representative of elo 1800, 1900,2000,2100,2200,2300 and so on.

Such as popular open source engines
TSCP
Gerbil
Micromax
Chesley
Scidlet
Typhoon

And try and find the engines that's statistically fastest to checkmate them

I'm doing work on a quantitative "aggression test". It involves beating a 2100 FIDE Elo engine in certain positions and shows an engine's tendencies towards king attacks. It doesn't test for strength.

What is the most aggressive chess engine out there, over 2700 elo? I was wondering if Ed & Chris had cooked something up in this department...is the new CS_Tal still private for instance?

bit late to the party, not long ago I tested HIARCS14 at 1600 elo (around 1900 FIDE) versus various engines. Was curious to see which engine can manage to checkmate the fastest i.e which engine goes "straight for the throat" against non-perfect play response. I made them play thousands of bullet games, some tests done without opening book and others using gambit opening suite. I still cannot say that I have come to any particular conclusion, mainly because I don't know how big the correlation between "most aggressive" and engine prioritizing heavy attacks on opponent king is. But according to the statistics these engines scored the best:

1. DisasterArea-1.65 (tweaked parameters)
2. rodent-IV - (Suicidal Gambit personality)
3. opental 1.1
4. Wasp 4.5 (tweaked parameters)
5. spark 1.0 (tweaked parameters)
6. Zappa Mexico II (tweaked parameters)
7. ShashChess24 - (HighTal personality)
8. Pedone 3.0
9. Wasp 6.0
10. Rebel-14.1.2 CSTal
...
42. ChessMind_082

if anyone is interested I will post full .pgn database and statistics as well as the overall EAS score.

P.S I can provide download links to the engine and parameters used for anyone interested too..
P.P.S I'd love to see if Mr.Pohl is interested to test these engines

I am sorry, but my EAS-list is calculated out of the testgames played for my SPCC-ratinglist. And this list is focused on the best engines. So, engines like OpenTal or Rodent are much too weak for a testrun.But Pedone 3 and Rebel 14.1 were tested by me. And they are very aggressive.
You can take a look at my full ratinglist, with all engines since 2020 in:
https://www.sp-cc.de/files/spcc_full_list.txt
Scroll down to the end of the list, there you find the EAS-ratinglist of all these engines (more than 1 million games played, each EAS-calculation takes more than 2.5 hours...)... Pedone 3 is on rank 3 and Rebel 14.1 on rank 6.

The only engine, I could test, is ShashChess24 - (HighTal personality). I will do that in the near future. But right now, I am testing Stockfish 221004, then Berserk 10 and Alexandria 3 will follow, so please be patient.

But I would love to see the EAS-ratinglist, you have done, with all the engines, you mentioned here (icluding the second ratinglist with all statistics, the tool builds). Perhaps as a small download, because the second ratinglist is not fitting in a talkchess-thread-window.

By the way: What about Uralochka 3.37c ? And Velvet 4.0.0? Very aggressive (see my full EAS-ratinglist or my Top10 alltime EAS-ratinglist at the bottom of my EAS-site:

Wow, thanks for sharing the above parameter. It was effectively annihilating lower order engines as quickly as possible. Teaches lessons on attack, sacrifice and pure gambit play.

I am using Stefan's EAS 4.1 tool on my own hobby chess rating list and OpenTal 1.0 is by far the most aggressive engine I have tested based on that rating. Below is my top 20 using EAS and note another one to consider is Stockfish 5 Fury which is also based on modified settings via UCI settings.

CSTal (#11) is Chris's work.

Each engine played several thousand games.

Code: Select all

***************************************************************************** 
*** Engine Aggressiveness Tool V4.1 Score points Ratinglist 
***************************************************************************** 
Score is: (percent*100) of the percent-values of the sacs (1-5+ pawnunits) 
calculated out of the won games by the engine, only. 
So, a weak engine (with a small number of won games) can get 
a high EAS-scoring, too, when the percent of sac-games in the won games 
is high (and the number of short wins). Higher pawnunits-sacs give bonus-points: 
1 pawnsac = 2x points  *** 2 pawnsac  = 10x points *** 3 pawnsac = 20x points 
4 pawnsac = 40x points *** 5+ pawnsac = 80x points *** 5+ Queensac = 150x points 
Additionally, very short won games (percent*100) give bonus-points. If the short 
games ended before endgame (a check for low material is done), then these points 
are quadrupled (4x): 
60 moves= 1x points *** 55 moves= 2x points *** 50 moves= 5x points
45 moves= 10x points *** 40 moves= 30x points.  
Since V4.1, the tool also searches for "bad draws" and adds points for the good 
draws ((percent of good draws (out of all draws)) exp3 /15) 
Bad draws are games, which were drawn before endgame was reached (except the 
games, were the engine had a material disadvantage) and draws 
after the engine had a material advantage of at least 1 pawn in the game.

45 moves= 10x points *** 40 moves= 30x points.  
Since V4.1, the tool also searches for "bad draws" and adds points for the good 
draws ((percent of good draws (out of all draws)) exp3 /15) 
Bad draws are games, which were drawn before endgame was reached (except the 
games, were the engine had a material disadvantage) and draws 
after the engine had a material advantage of at least 1 pawn in the game.

Yes, I agree. I used OpenTal, when I designed my TheKing-personalities, using TheKing 3.50 engine. And there, OpenTal was the most aggressive engine by far (more aggressive than TheKing aggressive-personality). OpenTal plays insane (look at this list here: 61.78% of all won games of OpenTal included a sacrifice (of at least one pawn) - crazy). But it is only around 2300 Elo strong.

By the way: Using the polyglot-adapter, I made a version of OpenTal 1.2, which runs in FritzGUI (normal version does not!):

(You must change number of Threads (I set it to 8 (8 is the highest possible!)) and Hash in the polyglot.ini-file (both parameters are at the end of the ini-file)). The polyglot-adapter was renamed to OpenTal_1.2_x64.exe (use this file for Create UCI engine in Fritz GUI, not "enginebinary.exe" (!!!))
