In addition to Jon's suggestions:

Simplex, CuckooChess, Ifrit, Red Queen, Greko, GarboChess, Protector, Pepito, Daydreamer, OliThink.

There are probably several that I have missed.

One I forgot: Gaviota is also open source and works well on Linux + windows.

Thanks, I'll put it on the list too then!

After my 100 games match between Sloppy and Fruit:

now running Sloppy vs Pawny (50 games) and Sloppy vs Sungorus (50 game).

Actually I think I was mistaken: there is a Linux binary but no source (it is closed). Only the tablebase code has been released.

NB: The offset is such as to give Sungorus 1.4 a score of 2402 elo, consistently with CCRL 40/40.

Currently running GNU Chess 5.1: 100 games vs Fruit, 100 games vs Sloppy and 100 games vs Pawny.

Actually Sloppy is 1 CPU. I ran it in command line and it said 2 CPU detected, so I assumed it was SMP, but in fact it only parallelizes the perft calculation (which is irrelevant to playing chess). Doesn't change the results, but I can now play Sloppy's games in //, two games at a time

In addition to Jon's suggestions:

Simplex, CuckooChess, Ifrit, Red Queen, Greko, GarboChess, Protector, Pepito, Daydreamer, OliThink.

There are probably several that I have missed.

most of these are either windows only, or dont work. cuckoochess needs some java stuff to work, can't be bother, I just want a single executable
I'll try protector though. And Olithink seems to have problems in its xboard handling code.

I'm sure that I have misunderstood something. None of these are windows only. Jim Ablett has compiled each of these engines for both Windows and Linux. I was assuming you could do the same with the source files bundled with the executables on his site (except CuckooChess, which is in Java).

Ah yes, indeed the Jim Ablett compiles for Simplex and Greko work fine. I'll put those two on the list, after Umko has finished.
