I´m predicting around ~10 ELO over SF4 (maybe more) on self-testing and much more (like ~20 ELO) against foreign opponents like Houdini and Critter as they use "time management tactics" hardcore to win games. This will be the end of false magicians.

Stockfish number 1 soon!

can anyone do engine matches (at least 100 matches) for the latest

Stockfish (29-08-2013) engine?

I'm doing the tourney too

and my result says Stockfish (29-08-2013) is super strong

and stronger than all the other engines in that tourney I'm running now

we should compare the engine match results!!

started a new tourney with the aforementioned engines

after hundreds of matches
I'll post the whole pgn file and the results    

now I know how to use
"use the same opening line twice"

so each engine will use the exact same opening in reversed colors!!!

Stockfish 020913 (2013 9 2)

Rewrite KBBKN endgame

This was thought to be a draw but the bishops generally win. However,
it takes up to 66 moves. The position in the diagram was thought to be
a draw for over one hundred years, but tablebases show that White wins
in 45 moves. All of the long wins go through this type of semi-fortress
position. It takes several moves to force Black out of the temporary
fortress in the corner; then precise play with the bishops prevents Black
from forming the temporary fortress in another corner (Nunn 1995:265ff).

Before computer analysis, Speelman listed this position as unresolved,
but "probably a draw" (Speelman 1981:109).

the tourney is almost finished and I'll post the whole pgn and the result soon!!

I only ran like 100 something matches or so for the engines

thus the statistical noise and the size of error (in Elo ratings fluctuation) are big

so the result here is not very accurate
(because we have to run the matches for like 1000 times)

so can any of us do hundreds or matches (at least 500) for the engines to get the accurate tourney results for all the chess enthusiasts?

In longer time controls however Stockfish creeps up very closely to Houdini 3!
