Re: is this a fortress?

Some weekends ago, I played a game as black where my opponent had a chance to defend my attack by trading a queen and pawn for two rooks to reach this position: 3k4/2p3pp/5p2/8/2N3P1/PP3RP1/2q3PK/8 b - - 0 34 During the game, I felt this would be a fortress since even if the rook can be pushed off ...

Re: Honey-X5i and Crystal-Honey-X5i Dual Release!

This final testing before next release- one last shot to make sure playing strength is reasonable - it should never be more than 20 Elo weaker that the SF its as based on. Sometimes it has been, as I have added code that gave it a nice problem solving effect, but ultimately the derivative will get ...

Re: Honey-X5i and Crystal-Honey-X5i Dual Release!

You can use mulitipv - which shows all the moves and say of you want is multipv setting of 16, but show only 4, set tactical to 4 and and multipv to 4. But then I can't use exclude-moves. The point of Exclude moves+Tactical setting is to be able to see the 5th, 6th, 7th and 8th best moves on the po...

Re: Honey-X5i and Crystal-Honey-X5i Dual Release!

One thing that would give Honey the edge over other branches would be an option for showing the scores of alternative moves when using the Tactical setting, since there's no other way to mix excludemoves and MultiPV (I continue to use McCain X with my change when I need a 5th alternative after the ...

Re: question about weak level of engines

I prefer the weak levels to have the following properties: 1)They are not deterministic so humans cannot learn a fixed way to beat them. 2)Their playing strength is fixed and not dependent on hardware or time control. Are there engines with weak levels that have these properties when the levels are...

Honey X5i Crystal-Honey X5i Binaries of all flavors are towards the bottom of each release page, will add more notes in few days headed to my nephew's a wedding at the shore for tomorrow! One important note - ALL weaker levels ( play b y Elo or adaptive play) should be used with ONLY one core or th...

Re: Stockfish mates Allie in 34 moves / TCEC

You really think 16. ... b4 is losing? I don't see it! I said probably losing, I am not sure of anything. From the analysis posted above, the line is : 16. ... b4 17. axb4 cxb4 18. e5 dxe5 19. fxe5 Re8 20. Kd1 Bxd5 21.exf6 hxg5 22.hxg5 g6 23.fxe7 Rxe7 24.Ra6 Rc7 25.Qd3 Bc4 26.Qd6 Qxd6 27.Rxd6 Re8 2...

Re: CCRL, FIDE and Ratings

The last few months, I have been focused on the UCI_LimitStrength feature , trying to make it more meaningful to the user. Unfortunately, it took me a while to realized that CCRL ratings, as good as they are at the higher end, were very frustrating to work with at the lower levels as they were tota...
