Convert Fritz DB to Stockfish

I'm thinking about switching to Stockfish. But I have about 200 games in my Fritz DB I want to move over to the Stockfish DB.

Any suggestions on how to port the games to Stockfish?

I like pizza.

I really really like pizza!

really.

SOrry if you are hungry now. This is one of the great new features on chess.com - gotta get 4 responses to your post before anyone can see it.

Perhaps export to PGN? I'd expect Stockfish to be able to import PGN.

Lucky I've just had my breakfast… 

Must have been a power breakfast. Was it pizza?

I've been up for hours and had 3 cups of caffiene and didn't think of that.

Thanks.

A collection of 200 games is trivial to move to any other chessmunching software. (There can be a problem movig a million.) This is usually done by simply exporting the database (collection) as a PGN file (Portable Game Notation) and then importing it to the new software package.

You guys know if Arena orStockfish actually have a dB system? I have one rather large PGN file that takes a couple of minutes to load with Arena. I will use it often and would rather have it instantly available and searchable.

Arena's DB functions are very basic and primitive. I don't think it even has the capability to search positions.

If you want to switch to Stockfish (=chess engine), just register the stockfish.exe in Fritz (=chess GUI = graphical user interface) as an uci (=universal chess interface) engine. Information how to do it is in the help file. It is basically the same process like in other chess GUIs like Scid, Arena, ChessBase, etc. You can keep your game database like it is.

It appears it doesn't.

Okie. So here is the situation. I was using Fritz. I had a dB of games I would search by position often. I still need this functionaltiy without using Fritz.

Any ideas of an alternate software that can do this?

Scid vs. PC?

Also, I haven't tried ChessX, but it might work.

You will also need to set the 'Hash' and, very important, 'Threads' option.

Feel free to ask questions.

Hash and Treadhs options for what?

Hash size defines how much computer memory the engine has, to store learned knowledge.

Modern computers often have more than one processor (eg. my laptop has four). Stockfish by default uses only one thread (= other word for processor). Number of threads defines how many processors Stockfish can use, which will make Stockfish play stronger. Eg. i let Stockfish use two threads, half of processing power of my pc.

But before this becomes relevant, you must first register Stockfish as an uci engine in your Fritz GUI. Have you done? Which Fritz do you use? I have an old Fritz 8 here, to compare. It is the 'Engine' -> 'Create UCI Engine...' option on my Fritz 8.

Yet I can't even understand how it even works! lol!

Thanks Nils. I actually know this stuff. I just didn't know which software you were talking about.

I am messing around with SCID vs. PC right now. It seems to have all the functionality I need.

I have 4 processors as well. Do you have any suggestions on the settings?

i have 8 GB RAM so i can use 4096 as Hash (=4GB ~ half of RAM). See also here. Unfortunately Stockfish logs no information how much of that ram it actually uses, i guess much less (The Stockfish developers currently have chosen not to log this information, cant find the thread any more, it is somewhere on http://support.stockfishchess.org/). I know that in blitz games or in analysis, when positions change fast, a huge RAM can be contraproductive, only in long games when position slowly changes, it helps. default for Stockfish is afaik 128.

i use 2 of my 4 processors but 4 is fine also, as Windows will manage this anyway.

The Task Manager can be helpful to figure out the right values:

Thanks for the suggestion of Scid vs PC. It seems to have what I need.
