1.- Stockfish 111113SL Large Pages Ipman = 3220
2.- Stockfish DD = 3212
3.- Houdini 4.0 Pro B = 3210
4.- Stockfish 191113 64 SSE4.2x = 3204
5.- Houdini 3.0 Pro = 3172
6.- Komodo 6.0 = 3166
7.- Amitis 16-10-2013 = 3.160
8.- Stockfish 4= 3119
9.- Critter 1.6a = 3093

I would make 2 comments. I am not sure what "Estimated ELO Performance" means, as Elo itself is already an estimate (based on a finite sample). And pursuant to this latter point, I think it would be good to indicate (say with the final list) the expected error margins on the ratings from 640 games.

Thanks for your comments BB.

1.- Estimated Elo Performance means that the ELO you can see in my list is not very refined. There are different ways to calculate ELO and I us the simplest and less accurate one. I introduce the word 'estimated' to make clear this fact to the readers of my posts.

2.- This year 2013 I have produced and shared with the computer chess community -in other fora- more than 30,000 games. Each game lasts 8 minutes and 40 seconds on average and generates around 3 Billion nodes each engine per game. I am sure you know that the bigger the sample, the lower the error bar. The list posted comes from 30,000 games, rather than from 640. This is the reason I have no interest at all in error bars and therefore I don't calculate them.

Regards,

Tom.

STANDINGS FOR INCREMENTAL TIME CONTROL GAMES ( Second half of this Tournament):

2.- Stockfish 041213 101.5/200
3.- Stockwood 031213 101.0/200

5.- Stockfish DD 96.5/200
6.- Komodo TCEC 64 88.0/200


FINAL STANDINGS AFTER 1.200 GAMES

1.- Houdini 4x64xCT0 220.5/400 55.125%
2.- Stockfish 041213 203.5/400 50.875%
3.- Stockwood 031213 203.5/400 50.875%
4.- Stockfish DD 199.0/400 49.750%
5.- Stockfish 111113SL 196.5/400 49.125%
6.- Komodo TCEC 64 177.0/400 44.250%


Although the number of games is not big enough, my preliminary conclussions are:

- What an impressive win for Houdini 4.0!. In my computers Standard version with Contempt ‘0’ is stronger than Pro version with Contempt 1.
- We are lucky to see the fast improvement pace in computer chess: The previous leader of my ranking -Stockfish 111113SL Ipman’s compile with Large Pages- has been surpassed by all other Stockfish in this test.
- Stockwood has proven to be very strong. I will follow his further development.
- The performance of Komodo TCEC –current TCEC world champion- has been disappointing in this tournament.
- The efficient and creative Stockfish team has still work ahead to reach Houdini 4.0 Standard Contempt ‘0’ level. Go, Stockfish!.

Regards from Barcelona.
