Yeah, I don't know if you saw my edit in my previous post. I was actually expecting 20-25 Elo from Stockfish 2.3.0 because of the VE_09 performance. I'm not sure where the VE_09 version is getting the extra Elo from.
Strange, ...and disappointing.

Re: Stockfish +80 ELO Patch
Well, 2.3.1 chess960 testing is underway, so we will see how that turns out Standard chess 404 has had a few 2.3 games http://www.computerchess.org.uk/ccrl/404/cgi/compare_engines.cgi?family=Glaurung&print=Rating+list&print=Results+table&print=LOS+table&print=Ponder+hit+table&pr...

Re: Stockfish +80 ELO Patch
Looks like the patch made it into 2.3.1 this weekend.[1] However, it looks like it could possibly be tweaked to provide additional Elo in the future.[2] [1] http://blog.stockfishchess.org/ [2] https://github.com/mcostalba/Stockfish/commit/a2976fd6110efc40507029a8b5c7b892a828b874#commitcomment-1890917

Re: Stockfish +80 ELO Patch
I wonder whether Stockfish 2.3 has incorporated some of this? Not yet, the patch has just got to the point where the maintainers are willing to take a look at it and test it out. If the tests hold up, however, I'm sure it will make it in. I wouldn't be surprised to see Stockfish 2.3 challenge Houdi...

Re: Stockfish +80 ELO Patch
I guess it's not 80 Elo as originally claimed by the author, but it is giving a 99.99% LOS over the older version in initial testing.[1] Wins: 3390 Losses: 2972 Draws: 11323 LOS: 99.999992% ELO: 8.213465 +- 99%: 6.746506 95%: 5.124415 Win%: 51.181792 +- 99%: 0.969791 95%: 0.736740 [1] https://github...

Re: Stockfish +80 ELO Patch
I noticed another patch recently checked in by Marco which claims a 20% performance increase in perft.[1] I'm not sure what perft is, I guess that is a move generator performance calculator or something, but 20% performance increase sounds pretty significant! I also read that Houdini Chess 3.0 will ...

Re: Stockfish +80 ELO Patch
It looks like Gary Linscott just optimized the patch by Ryan Taker to use bitboards to count the pawns on a rank.[1]
Who knows what kind of ELO improvement this means now.

Re: Stockfish +80 ELO Patch
Yea, Marco's tests indicate no ELO improvement, so it could just be a big disappointment. :( Speaking of official Stockfish builds, what version is this? http://www.computerchess.org.uk/ccrl/404FRC/cgi/engine_details.cgi?print=Details&each_game=1&eng=Stockfish%20VE_09%2064-bit#Stockfish_VE_0...

Stockfish +80 ELO Patch
Hi: I just noticed a patch for Stockfish222 which claims to increase ELO by as much as 80pts.[1] The problem is that Stockfish does not take into account how many pawns are on the 7th rank when considering to move rook or queen to 7th rank. This patch fixes that issue. I think this is really interes...

Re: CCRL 40/40 Testing Conditions
Hi: Quick question. I think the answer is obvious, but I just want to make sure. When you use the tablebases, the GUI takes over for the engine, correct? Because stockfish does not have tablebase support built-in, while Houdini does and I was wondering if this could affect the ELO rating. If the ta...
