Re: Opposite Color Bishop Endgames

That is why I posted as I did. In your link, I recall Majid Ansari's post of over five years ago when he wrote: I actually watched SF win a very nice opposite bishop endgame against Houdini. The struggle in the endgame was to avoid a drawn opposite bishop endgame and I thought SF handled it extremel...

Re: Opposite Color Bishop Endgames

One should remember that the design goal of engines is in general not to be good at chess, but just to have a high Elo. If worse programs score better in games, it is preferred to make them worse. Hi HG, Those are indeed words of wisdom. That's why I post here, to learn such wisdom. I knew that was...

Opposite Color Bishop Endgames

Hello All, The following 8-piece endgame just arose in a Raubfisch X40a3-Cfish match: [d]4b3/8/6k1/6p1/p6p/K3B1P1/8/8 w 01 Virtually all humans immediately see that this is a draw. White will exchange pawns and then sac his Bishop for Black's dark-squared pawn, leading to a King versus King, Bishop,...

Re: asmFish

Thanks for your valued input, Syzygy. Rather than overall playing strength, I was instead testing tactical acuity. In that 100 game match with long TC, asmFish/PedantFish failed. That was a surprise as the test was skewed in its favor, as previously explained, given the latter's roughly 25% speed ad...

Re: asmFish

Hi Mike, Thanks for your interest. Like you, I wish the asmFish effort was sustainable since conceptually, its superior speed would make it the strongest Stockfish (SF). I'm auditing the games now and something interesting is apparent. It was my perception while watching the games that while asmFish...

Re: asmFish

For those who are interested... I'm stopping the Stockfish (SF) vs. asmFish match after one week at 100 games. The score is now 15:6 in favor of SF after 99 games (game 100 is 40 moves deep and equal). That's nearly a 3x greater victory factor! Here quality was a greater factor than calculating spee...

Re: asmFish

Hi Dann and Kai, and fellow members, Thank you gents for your thoughtful posts. As a result, I wonder if I should have worded my initial post better, since it's apparent that you've misunderstood me, Kai. I know that results from just 20 games in an on-going match is far too little to draw conclusio...

Re: Raubfisch

Hello Mike,

I sent all 200 games to Graham Banks and then deleted them, so I could group the subsequent match games there. But if you'd like them, I'm certain Graham will oblige.

As for sharp lines, Mike, I'll personally email you the Opening Book I created.

All the best,
Steve

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...
