GreKo 3.3 released.
http://greko.chess.googlepages.com

Two bugs fixed. Minor changes in search.

Thanks Vladimir for the quick response.

Unfortunately it seems GreKo isn't pondering at all now .

Volker

Could you please post here sample of debug-file?

Maybe I misunderstood protocol description?

Should engine start pondering after the following:

(GUI) > hard
(GUI) > force
(GUI) > e2e4
(GUI) > e7e5
(GUI) > go
(engine) > move g1f3
<ponder on not here>... - ?

Does "force" command turns pondering till next "hard", or just till "go"?

I mean, turns off?

It is also visible with the "top" tool in Linux and should also be
observable with the task manager under Windows.

I tried to fix the bug with pondering. Now it works, at least on my machine under WinBoard 4.2.6 and Arena.

Here is my winboard.debug:
