How odd, and after all these years.

Here are some ideas.

How does Rebel process this line:

Code: Select all

 position fen r3rbk1/p1qbpp2/1p1p2p1/3P3p/3BB2P/2P2QP1/PP3P2/R3R1K1 w - -

1. The error is almost certainly caused by the position not being the start position
2. Is it assuming the FEN has a certain number of fields and what does it do if there aren't the number of fields expected?
2. Does it need "moves"

Nothing strange as you can see.

What happens at your end ?

Hi Ed,

Here's a video of it crashing from the terminal:

https://www.loom.com/share/45278d4abb23 ... 7111b31fed

As I said, I did this four times and it crashed three time i.e. not every time. I suspect it has something to do with the "ucinewgame" command. Hope you can track it down!

I’ve not looked at this for three years, and don’t intend to now.
1. Is nonsense
2. It compensates for dumb FEN strings, up to a point
3. No

Either the FEN is duff, or the Shredder interface is weird. I don’t have Shredder and don’t intend to get it. Fritz neither.

Everything if fine if you write your own compliant UI in python. Or if you use cutechess. The engine is free and there’s no way I am going to spend time and energy fixing every issue with third party software.

If, very big if, I decide to work more with Ed on a new version 3 later this year, it’s pretty unlikely the UCI code would be any different. However, given the hate and flak and personal comment (not accusing you here of course) we take for releasing anything plus the universal lack of brownie points for giving away free engines and huge amounts of time and effort, plus the demands we port to every machine under the sun and be compatible with every man and his dog variant else we get flamed, plus there’s zero financial reward, unlike in old days, I wonder pretty much why I should even bother.

Hi Chris,

Thanks for the reply. I appreciate the engine as well as the work you've poured into it — and I respect that you're free to do as you choose.

All the best,

Steve
