Some hot news:

Stockfish 2.3.1 is available
http://stockfishchess.org/download/
Changes:
"ELO increase is very limited, it is mainly a minor release to flush the accumulated work. From the user point of view the biggest thing is that SF should not crash anymore even with many threads because a nasty SMP bug causing a rare but repetitive crash has been fixed."

Marco.

A good engine for analysis, but compared to this one:
Houdini 3
Robert Houdart:
"The engine development is completely finished, but there's still a lot of work in packaging and documentation (e.g. write the User's Guide). Hopefully around October 10.
Some info about it: http://talkchess.com/forum/viewtopic.php?t=45303&start=10

Mr Houdart ran some tests on long time controls (90 min+30 sec/move starting from 60 Noomen suite positions, one core each)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=25731
Very impressive results:
Final result of the Houdini 3 - Houdini 2.0c match: +48 -15 =57
You can download all of the games from http://www.cruxis.com/download/Houdini3_Houdini20c_90min.zip

Well, obviously that's the engine for my future analysis!  Wink
I'll post some of these games here - hope you don't mind!

Great analysis tool, but only for those who can work with it. (A little reading is needed and a lot of hard work to become good at it.)
As for the prices (special offers, discounts and alike), look at: http://chessok.com/shop/
Cool

Aquarium seems to get some good comments here as an analysis tool.  Is this a competitor to Chessbase or in the Chessbase family?  Also, how much does it cost?

A candidate to be the best analysis program: the new version of Critter uci chess engine (created by Richard Vida) - 1.6
Completely free, yet powerful - maybe best for endgame analysis. Download versions are at:
http://www.vlasak.biz/critter/

New improvements:

"Richard Vida
Posted: Fri Jun 15, 2012 7:54 am Post subject: Re: Critter 1.6 released!

Recent changes/additions:

- Automatic detection of SEE4.1 capable CPU. Both SSE4/non-SSE4 codepaths are now compiled in a single executable and chosen dynamically at runtime.

- Large pages suppport. This requires sufficient user privileges and right OS settings.

- Own book is automatically turned off when analysing.

- Engine now honors multi-pv even when the root position is a tablebase hit

- Session file now supports IDEA. SF writes are disabled at root when any moves were excluded.

- Session file writes are now protected by OS IPC mechanisms (semaphores/mutexes). Same session file can be accessed concurrenlty by multiple engine isntances without risking corruption (useful when running IDEA)

- Removed UCI option "SF strategy", now its value is hardwired to "depth"

- New UCI option "SF move limit" which disables learning after game has reached given number of moves. When set to 0 this option is ignored.

- New UCI option "SF material limit" (0..32). Disables learning when total amount of material is less than the given amount [Q=6, R=3, B&N=1]. When set to 0 this option is ignored.

- Gameplay related changes:
* Tweaked blocked-pawn recognizer
* Skewer detection in eval
* King safety tweaks
* Pseudo-contempt: slightly increased preference of moves increasing pressure on the opponents king
* slightly increased preference of pawn pushes in semi-blocked positions
* Recognizing more types of drawish endgames

- new console mode commands "sf probe", "sf delete", "sf store" for mainpulating session file entries

Richard"

Uninstall and reinstall the engine, then when you add the UCI engine, tick the box 'below priority'

Thanks! Smiley

The free Houdini 1.5a that I have seems to gradually bring my computer to a near standstill when analysing on ChessBase 10 - is this normal?


Uninstall and reinstall the engine, then when you add the UCI engine, tick the box 'below priority', if I recall correctly. Reducing the number of megabytes on the hashtable can also help.
  

All our dreams come true if we have the courage to pursue them.

Not a bug but maybe something to know. Komodo has a drawscore=-5 as default (in analyse mode too). It is maybe better to set this to 0 when you use it for analysis. And it is even more important to do this if you use Aquariums IDEA analysis, else you would probably get too much of something that looks like a odd/even scoring.
For IDEA use (or while excluding moves in normal analysis) I wouldn't thrust to enable positional learning, it could give some unpredictable results. (This latest is for other engines than Komodo.)

As a correspondence player, I too highly recommend critter 1.4, also Komodo 3 (4 is out, but it costs money and its extremely buggy while it only boats 10 pt higher elo than 3).


On the rybka forums Komodo 4 gets high praise as an analysis engine. The main reason given is that it's got better positional understanding than the other engines.

I haven't seen any mention of bugs in Komodo 4 - and, as the webmaster of http://komodochess.com, I'm always on the look out for people mentioning bugs.

Many thanks, Vass, Hacker and Vladimir. Now I've read about it, Houdini's Aquarium seems indeed promising, and as someone who spends lots of time with analyzing I should certainly try it. (I didn't try the first version of Aquarium, because in some blogs a bit too many flaws were discussed.)

In some cases (endings, KI positions and so on) Rybka had problems, e.g. in endings Deep Shredder was better. Other programs were useful, too, to get new ideas, so I'll gladly check your interesting suggestions, including Critter 1.4.


Hi Stefan,
             How are you?. Replying you after a long time. Read all the comments here.
Let me tell you few things. The topic is "Analysis programs" and not Analysis tools, let me first elaborate on the engines first.
The top 5 engines are good in analysing positions you want. All have their strength and weaknesses. Namely - Houdini 2.0c , Critter 1.4 , Stockfish 2.2.2 , Depp Rybka 4.1 and Komodo 4 MP(Yet to be released, now SP only)

Regarding feature rich it is Rybka 4.1. It supports Large pages, Preserve Analysis , Randomizer, Monte Carlo , Multipv_cp and 2048 cores in cpu.

Houdini too supports Large pages, Save Hash , Multipv_cp and 32 cores support with learning feature and Nalimov + Gaviota TBs support. But i find the learning feature a bit faulty in it.
The best learning feature is in Critter 1.4a which implements a session file. Very good for Deep Position Analysis and Backward Analysis in Fritz GUI if you know the right configuration settings.
Here is the link to Unofficial one -http://www.mediafire.com/download.php?w4x1kctds4oa9og

Unofficial, unsupported, and only 64bit Sse4 build:

- tweaked SMP implementation
- sligthly decreased Queen value
- time management: try avoiding blunders in sudden death games when in time trouble
- time management: fixed losing on time whith "ponder on" games on opponent's instant reply
- improved pawn blockage detection (3B4/1r2p3/r2p1p2/bkp1P1p1/1p1P1PPp/p1P4P/PP1K4/3B4 w - - 0 1)

The Stockfish 2.2.2 is good for analysis in IA but not feature rich. So you need a feature rich stockfish which is good for analysis.  Here is an Unofficial one.
Stockfish 2.1.1 PA GTB Gran2c - download http://www.open-chess.org/download/file.php?id=356]

The changes from Stockfish 2.1.1 include:

Preserve Analysis: Stockfish keeps in mind what you have analyzed and doesn't research it until you unload the engine. Perfect for backward propagation of scores and saving time for transpositions.

GTB: Allows the user to use Gaviota Tablebases in Stockfish.

Granularity=2: Allows Stockfish to have more precision on move scores, so that instead of 0.00 -> 0.04 -> 0.08 it goes 0.00 -> 0.01 -> 0.02.
Mac, Win32, Win64 & source included. Source maintained at: https://github.com/jeremybernstein/Stockfish_PA_GTB


The best GUI for Rybka is Aquarium because it uses its feature to the fullest.
Randomizer is good feature which I always use to get a General Idea of a position. Shared Analysis is another feature which is great with Deep Rybka 4.1 . If you haven't read then read here - http://www.chessbase.com/newsdetail.asp?newsid=5074]

You can do it manualy
Created a txt file  Deep Rybka 4 SSE42 x64.uci_b or Deep Rybka 4 x64.uci_b and type the following lines.

[ENGINE]
Parameter=%PID %CPUS
[OPTIONSA]
Preserve Analysis=true

And save the file with extension .uci_b in the same folder where the chessabase saves the uci file in appadata/roaming/chessbase/Engines UCI.
While analysing Just right click in engine window and Shared Analysis.

Another feature you can use in Aquarium is the Delta which uses MultiPV_cp for this (UCI3 support).
MultiPV_cp option is to limit multi-PV analysis to moves within a range of the best move.

I use 'delta' in infinite analysis.  Like set delta to 25 and variations to 200.  Then when you run the engine it shows the top move and all other moves that are up to 0.25 pawn worse.  In some positions it will show only one move but in other positions it may show many.  I spend a lot of time running analysis and setting variations to 5 (without delta) wastes a lot of time if there is only one good move.  On the other hand in some positions there may be 10 moves that are all good and I would only see 5 of them.  That's why you will  find delta a great feature.

Note on using Critter in Backward Analysis and in DPA
In IA use Always Resolve Scores and Depth Strategy (say =10) and this seems to be the preferred settings.

With a fast machine and Critter's new session file,  you can run with depth 25, with +1 at the root, with a branching factor of 4, 4, 3, 2, an analysis length of 7, and a window of 30, cutting bad moves.

Hope this helps you and all. After trying please answer me if its helpful to you.

Regards
Om

I think I should make this thread 'sticky' so it always remains at the top of the first page, as the best analysis program will always be of interest. Anyone disagree?



Done.

My main problem with sticky topics is that they too get ignored. Let's see what happens to this one.
