Fritz 16

I don't think that's quite right. I have a 64-bit Windows OS. Both 32-bit GUIs and 64-bit GUIs on my PC will run either 32-bit or 64-bit engines. I think the problem is that if your OS is 32-bit, then nothing that's 64-bit will run on it.

@m-p-b I could use fritz 13, but is ridicolous, the fritz devs missed such a nice feature in a version that claims to be from the features: human and user friendly! While in 2013 i was playing an equally user friendly game with friend and `handicap and fun`Also because if I play on line with real humans I  cannot target the player style I want. I really do not see any logic in their choice to get rid of `handicap and fun`

@Escherehcs 

there is also a GuideBookFile: guide.bin and a MainBookFile:rodent.bin, I am wondering if they could influence the ELO of amy.txt as well.  I put one processor instead than 4, but is strange that if I press the button New game, and I move the white the black does not move at all, I also unchecked permanent brain and tablebase.

I am quite disappointed fritz misses such an important feature present in F13

I don't think the opening books are affecting Amy's strength. If you look near the bottom of the Amy.txt file, you'll see that Amy actually uses the much smaller micro.bin opening book.

update, I am playing against emy in Arena as well, setting even the engine at 25%, still is really strong, no way is an ELO ext of 1000-1400 I win easy this kind of range, but I lose against Arena emy. with 100% goes 16 deep in less than 2 seconds, if I put 1% strenght starts with 5 deep and arrive to 7-8 in one second showing 5 lines

update 2, even setting micro.bin in Arena,

if I play a strong for a 1400  https://en.wikipedia.org/wiki/Colle_System

computer opponent open the bishop c8 to prevent mine bishop positioningin d4... quite a strong opening book to be micro....

I would expect that Amy would play the same regardless of how many threads are used, since the search criteria are set by the options in Amy.txt, such as:

setoption name NpsLimit value 64

setoption name EvalBlur value 48

you know a lot of stuff, node per second and blur are equivalent to 1000-1100.

how come can be so strong?

I edited the post above with a picture of how replies well.

My guess is that, for some reason, the Rodent engine isn't seeing the Amy.txt file. Maybe you're not getting the path right, I don't know. Try copying the Amy.txt file and paste it into the same folder as the Rodent engine file. Then just specify "Amy.txt" (with no path) for the personality.

I set it nps 20 blur 14, despite all i put the strenght as 1 percent

and look how much goes deep and how destroy my queen gambit

Try restarting the engine in Arena. (Right-click your mouse inside the engine analysis window, then click on "(Re-)Start engine".) When you do that, what information appears in the engine analysis window? For me, it looks like this:

is correct, please notice that is indicated 2000, possibly is the ELO assigned

I did also as you suggested putting amy.txt in root directory(not Amy,txt as you said), then as you suggested from the txt file I assigned the two micro.bin always strong openings, but finally I get 1 deep (this is independent from how is set the strenght because as you were noticing it depends by blur and nps

Under Fritz I noticed that although is recognized as  Rodent the Engine, the blitz  game is playing with ...FRITZ as you can see from the image

(and thinking that I wanted to have a night to relax from dev bugs ahahah) Thank you anyway today I wrote also to the dev of the engine asking if could jump into the forum, if has a chess.com account

update, I restarted engine as you suggested... and i get even the LogStackTrace that amy.txt has been loaded. At this point finally the engine is replying with stupid moves against my Colle openings.(Please see below)

Arena is solved,  new use case:

now I am curious to know how to feed Rodent as `playing`` not kibutz/analysing engine in Fritz so that I can use micro.bin and amy.txt from root and/or deactivating the other fritz functions as hashtable, permanent brain and so on.

The 2000 elo that Arena shows is a meaningless number. This number is set by the user - It has nothing to do with the actual strength of the engine. (The 2000 elo is just the default value assumed by Arena for all engines.) I could set this value to 1 elo or 300,000,000 elo, and it would have no effect on the actual playing strength of the engine. :)

Also, in your Fritz screenshot, I think it's telling you that the engine is the Rodent engine, and it's using the Fritz 16.ctg opening book.

update what i do is setting the engine, save the result, press ok to the GUI. Then I go for a 10 min blitz game, then i press new game, and the engine is Fritz in the notation not rodent, that I an see below think different lines that the ones played by opponent AI pc

GOT it is just as you said.  Just  needed to ignore the Fritz.ctg, as I can see Ivano-RodentIII and the parameters are the ones amy.txt and micro we've spoken.

Cool, PLEASE Look the stupid reply i get with Colle, now I do not need fritz 13 anymore, as I guess I can personalize the personalities hi hi

Thank you very much escherechE YOU  of devs

happy coding happy chess

My pleasure. If you're happy, I'm happy.

Of course you can install and run a 32-bit GUI and a 64 bit OS.

And.. of course you can not installed a 64-bit GUI on a 32-bit OS.

That is not what I said... I said you can NOT run a 32-bit engine on a 64-bit installed Fritz (GUI).  You can install Fritz as a 32-bit GUI on a 64-bit OS and then run 32-bit engines on it.  But why would you do that?  Just run the newer engines.

Sorry about that. When you said "OLD 32-bit engines WILL NOT run on 64-bit installations.", I didn't realize that you were referring specifically to the Fritz 16 GUI. (My 64-bit Scid vs. PC GUI does run 32-bit engines.) Those crazy Fritz programmers...

It's a good thing that the Rodent engine comes in both 32-bit and 64-bit flavors.

a la cart chess programs can lead to confusion  :-)

add computers into the mix and no wonder we are all starting to lose our hair.  :-)

A chess GUI, will run ANY UCI engine when the OS is 64-bit, and only the 32-bit ones when the OS is 32-bit.

This has nothing to do with the actual GUI being 32 or 64 bit.
