Re: hardest LCTII test position

Stockfish solves it in less than ten minutes This is quite slow Dann. Stockfish 1.6s 32-bit slightly smoother solved it in 1:43 on a slow Dualcore Laptop and in 40 seconds on Quad: r2qrb1k/1p1b2p1/p2ppn1p/8/3NP3/1BN5/PPP3QP/1K3RR1 w - - 0 1 Analysis by Stockfish 1.6s: 1.a3 +/= (0.44) Tiefe: 1 00:00...

Nope, the sligthly smoother scaling one (333,824 bytes) is the best.

Re: Trusting Databases

You should use a big computer database to determine evaluation weights.
The human databases, even the commercial ones, contain lots of silly moves that actually never happened.
The main reasons are unreadable Score sheets.

Re: Robbolito 0.09 New Edition VS Rybka 3

A second match Robbolito 0.09 X64 - Deep Rybka 3 x64 (4 threads) with the same conditions ended 13-27 (+4 =18 -18)

The claims of the Threadstarter are obviously hyperbole.
Dann's original smooth scaling approach didn't work for Stockfish (see CEGT private test), so why should it work for Robbo?

Re: Robbolito 0.09 New Edition VS Rybka 3

I am not proud to announce that Rybka on 4-core is not surprisingly better than Robbo on 1-core:

Robbolito 0.09 w32 - Deep Rybka 3 32-bit (4 threads)

21.5-28.5 (+10 =23 -17) 5'+1'' 5moves book ponder off

I want to do the same test with the 32-bit engines. Where do I get PB-5moves?

Re: Little test with both stockfish 1.6s versions!

I think that he is right though. I am seeing the same thing. The newer version trims a bit more. I guess that it is too much. I don't know. I have a Phenom X II 940 Processor. I like slightly smoother version more, so I will stick with it for the time beeing. It achieves the better results against ...

Re: Little test with both stockfish 1.6s versions!

I think that you can not draw any conclusions from these games. You'll have to match the two DC-compiles directly on your machine.
