Re: Perft(13) betting pool

Hi again: I am glad to see how Shawul's UCT run and also new Adam Hair's estimate based in estimating BF with polynomials and logarithms suit in my interval. I have worked a little on my 'method' and I discovered that is a little better than I expected! It can also estimates Perft in even cases of n...

Re: Perft(13) betting pool

Hi again Daniel: Thanks for your quick response. When I read your post I can do nothing but laugh! I did not understand anything, it is like Chinese to me (no offense to Chinese people or language). I know nothing about programming, but thanks for trying to explain to somebody than maybe understands...

Re: Perft(13) betting pool

Hi Daniel: I took a look on your new method: http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=417149&t=39678 The Perft count seems very good (it almost fits in my new interval (1.9804681 ± 0.0002024)e+18 , which is a total surprise for me!). I have calculated (I hope there are not error...

Re: Perft(13) betting pool

Hello to everyone: I redid by hand (only using the calculator of Windows) all the math involving the cubic polynomial adjust of my method because I was afraid that Excel approximations hurted a little my estimate. In fact, range width has been narrowed a little (from ~ |±0.013%| to ~ |±0.01022%|), s...

Re: couple of nice sacs from WCRCC

Hello Jon: The second position reminds me a lot the first position of Nolot test: http://en.wikipedia.org/wiki/Nolot They are not the same, but a lot of pieces are in same squares, and the star move is also the same: Nxh6!! Long time ago, first position of Nolot was very hard for engines, but now is...

Re: OTB human test positions

Hi everybody: The position is taken of Shirov - Carlsen of today, but instead of playing 44.- Qd5, I played 'my line', just for curiosity: 44.- Qxc3, Qxd7; 45.- Qxc4, Rc8 (I wanted to trade queens); 46.- Qd3, Qxd3; 47.- Bxd3, ... and here is the position. [d] 2r3k1/5p2/6pp/8/4P3/3BP1P1/5K1P/8 b - - ...

Re: Perft(13) betting pool

Hi again: I will use some numbers that were posted here: http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=416331&t=39678 Sorry for insisting so much with my polynomial extrapolation. I have done linear extrapolation (instead of quadratic) for Perft(11) estimate, to see if increasing (or...

Re: Some news about Houdini 2.0

Hello Mr. Houdart: First of all, thank you very much for keeping free your engines Houdini 1.5 and Houdini 1.5a. I hope both search and eval will be improved (if possible), because I have read more than once that Houdini 1.5 (and 1.5a, of course) tends to overestimate own Q against 2R in some positi...

Re: Perft(13) betting pool

Hi Mr. Muller: First of all, I want to congratulate you and the rest of people that are doing astonishing estimates with superb methods. Secondly, I do not understand the method you propose in your post (I am not so clever and please do not waste time trying to explain it to me). But reading it, the...
