Rybka 2.3.2a for FREE

GO to Zarkon Fischer's Free Chess Programs then go to the front page look the latest news an see how to down load the Rybka 2.3.2a uci chess engine for FREE. Rybka 3 is only 70 points stronger an Naum 4 only about 4 points stronger according to Ccrl ratings.

I prefer the toned down fritz 6 that comes with chessbase light.  Paradoxilly, I find rybkas analysis TOO good.  First and foremost, it's discouraging how GOOD the engine is.  It makes me want to say "screw it", and watch it's analysis with glazed eyes.  Phychological hurdle there.

But the main reason I don't like rybka is because I simply don't understand it's analysis.  It will say some magical moves, and then a few moves later black/white is winning, and I don't understand how I got there.  Fritz on the other hand is a complete duffer compared to rykba, but I understand the engine better, and know WHY his moves are good moves.

No comparison as engines between rybka and CM. CM is wayyyy behind the curve here.

Use CM for its lessons, rybka for top-notch analysis.

Kerplow whats the difference between Fischer an Bisguier.That should tell you the gap between rybka2.3.2a an Chessmaster 11000.

Yes but to get the latest engine you would have to purchase it.  Only the earlier ones are free.

Borgqueen i have already loaded Rybka 2.3.2a to Arena  mayurachessboard  Infinitychess an yes Fritz 9 an Fritz 11  guis an it works great on all check the guest book on zarkons site to get tips on how to down load peska which is a geat free training program an in it is the Rybka 2.3.2a uci engine file you load this file into Fritz 11 an the other Gui platforms.By the way you will find on zarkons grat site links to download all rybka chess engines up thru rtbka 2.2n2p mutiple cpu chess engines.I now run about 10 rybka chess engines on Fritz 11 several stronger than the Fritz 11 engine talk about a cheap free way to up grade fritz 11.on Fitz i use fritzs openimg book however on zarkons site you will find a good link to a free rybka opening book.

Ok you have deep fritz 11 the souped up ver,now it may be a bit stronger than Rybka 2.3.2a as i think its the single cpu 32bit ver.I think  your fritz 11 is a 64 bit designed for the newest computers.However if you have a older computer or the regular fritz 11 then the free rybka 2.3.2a 32 bit is a good upgrade an even on your deep fritz adding a uci engine not designed for the newer computers not sure how it would work try it an see works great on a regular fritz 11 gui platform.now rtbka2.2n2p i think is released for free is a mutiple cpu uci engine which in the newer computers that are able to take advantage of it may check in a few points stronger than deep Fritz 11.

You can download Rybka 2.3.2 straight from the Rybka website, www.rybkachess.com. I wouldn't trust any other sites.

Well it runs on deep fritz now on my regular fritz 11 i find it much stronger than fritz 11. i have a cub blitz rating around 1950 to 2000.For everyone with a cheaper older computer then we are stuck with 32 bit however i think thats prob 75% off all computers in use its a big free upgrade.Play it on deep Fritz an post how strong compared to deep fitz in play you find it to be.

This is another free engine that works well (although on the site I think the author does not recommend the Chessbase GUIs):  http://www.glaurungchess.com/

In general Rybka is a little slower at getting where it is going.  I have Deep Rybka 3 and run it in the Shredder GUI and it can be a little slow.  I use Rybka when I really really want to dig into a position.  I think any of the other powerful engines such as Fritz 11 are going to give great answers.

I will go on record as saying that if you buy Rybka 3 directly from the Rybka website that they give GREAT customer support through there forum as does Shredder and Hiarcs through emails. (chessbase not so much..)

This is another engine that is free that has gotten high marks:  http://brightchess.googlepages.com/

It works great in the Shredder GUI.  I think it is cool to have a few engines to a) Play against and b) the will give different opinions sometimes when analyzing.  That can be fun to dig into to see which one you like best!

I think part of the strength of Rybka is its programed with more chess knowledge so while it may not crunch as many positions per sec as fitz it more than makes up with better positional etc general chess knowledge.I find you can trust zarkons wonderfull free chess programs site as i have downloaded most of the programs listed there.If your on a tight budget Then Free is your only option.

hey try The Twisted Logic Uci engine its free has a 32 bit single cpu strength of 2800 but plays in a very unique style for a chess engine try it you will love it,an yes glaurung is a great free engine also i like its style of play.

Hi here is another nice free engine:

Here is the site most people refer to for comparisons but it doesn't give concrete definitions of style:

One other cool thing about purchasing Deep Rybka 3 is that you get 3 engines for the price of one.  He bundles in Rybka 3 and then a Rybka 3 Dynamic and a Rybka 3 Human.  They have different styles of play and analysis (not all the time, but enought to be fun!)

I can't comment on how Rybka 3 will work in chessbase as I don't use chessbase products.  You might want to put a post on the rybka forum asking if anyone has had any experience with Deep Rybka 3 in Fritz 11 GUI.

So far so good running Rybka 3 in the Deep Fritz 11 GUI, using Perfect15 opening book it seems to play pretty much as well as in Aquarium i.e. it beats DeepFritz 11, Hiarcs 12.1MP and Deep Shredder 11 in Engine matches in similar fashion (Sorry I could'nt be more precise). Biggest difference is I use Jeroen Book in Aquarium and Perfect15 in Fritz GUI for Rybka, game play so far is very much the same however bear in mind this is just based on 20 or so Engine matches so far. No big speed difference evident so if there is one it's not a big issue so far.

Rybka 3 works fine in Chessbase as an analysis engine and fine using the Fritz interface as a stand alone playing program

THE POINT is its FREE so why not try it.Check out the other RYBKA chess engines links on one you can download about @) or more older but vey good RYBKA engines some of which are rare.Zarkons site is a treasure of free programs.

Kerplow try 2.3.2a 32bit single cpu engine rated 3023 only Naum 4 32bit single cpu an Rybka 3 32bit single cpu rated 3093 are rated higher for most computers which still are made for 32 bit single cpu by the way Rybka 2.2n2p 32 bit is designed for one or more cpu s an on more than one is rated a bit higher than Rybka 2.3.2a 32bit an almost as high as a single cpu 32 bit Rybka 3.Not bad for free.

Rybka is a fast searcher, must faster than Deep Fritz. Rybka counts nodes differently that is why you see a low number and thus thinks she's slow. Rybka is the fastest searcher there is.
