Re: asmFish

However, the result is perplexing. After 20 games The results are not perplexing, merely meaningless. What is perplexing is that you persist in wasting time on these tests despite being told repeatedly about the small sample sizes, too-wide error margins and statistical insignificance of such tests...

asmFish

Hello all, I'm continuing to search for the tactically strongest engine to assist my ICCF performance. So, I'm now running a match between the latest iterations of Stockfish (SF) versus asmFish, both using my "Tactical" opening book. However, the result is perplexing. After 20 games with a time-cont...

Re: Raubfisch

Hi Dann, Some of the selected openings did indeed involve gambits, while some did not. But all of my opening lines successfully dropped the two chess engines into highly-unbalanced tactical situations which they competed to resolve. So, it's irrelevant how they got there. The only relevant question ...

Re: Raubfisch

Indeed, they are better, Graham. Nonetheless, they still have problems. In one of my latest ICCF games, I was white in a King's Indian. The position was equal, but all my engines claimed significant advantages for my side, even after searching very deeply. This persisted until Black's pawn storm dis...

Re: Raubfisch

Hi Dann, The fact that the games often ran over 100 moves confirms that the openings led to positions with material retention. There were no early "trade outs". I've presented the selected opening lines in an earlier post. Those lines are shallow, terminating quickly to force the engines to solve pr...

Re: Raubfisch

Hello AR, I respectfully disagree. My selected lines were sharp, unbalanced and asymmetrical, and tactically rich while avoiding massive piece exchanges. In my openings, pieces were developed rapidly and then stayed on the board. Many games lasted over 100 moves and retained a sharp nature throughou...

Re: Raubfisch

Hello AR, I've learned from previous engine tests that my openings extended too deeply - they solved much of the tactics for the engines before reaching the middlegame. Instead, I wanted to reach sharp and unbalanced positions as quickly as possible to force the engines to solve matters on their own...

Re: Raubfisch

Dear gents, I stopped the match after 200 games. The result was a 15 victory to 12 loss result in favor of Raubfisch X40 over Stockfish 3/31/19. Strictly on the basis of performance, this engine should be noticed. Statistically, this result could have been obtained by playing Stockfish against itsel...

Re: Raubfisch

Dear gents, Here's the match update: After 162 games, Raubfisch leads Stockfish by +4, 13 victories to 9. That's only 14% of all games being decisive, which seems very odd given the ultra-sharp opening book. I'll let the match run a bit longer as I need to do my taxes now. :-( All the best, -Steve-

Re: Raubfisch

Dear gents, Please allow me to address you individually. Guenther: Thanks for your contributions to this thread. I agree with you regarding Raubfisch's GPL violation, especially when the mysterious "author(s)" of Raubfisch admit that it's derived from Stockfish. So, the violation is clear. But, whil...
