Schooner 2.0.34 (UCI) and ponder

Post by ThatsIt » Fri Apr 05, 2019 8:13 am

Hi !

Extract from the "readme.txt":

- pondering allowed (xboard only)

Why not for the UCI-version of Schooner ?

Best wishes,

With the "Wb2Uci" adapter (2005/06/16) by Odd Gunnar Malin
ponder works under the shredder classic gui ! Perhaps using
the adapter weakens the engine a bit ...

Why would using an adapter weaken an engine? :shock:

Thats why i wrote "perhaps".

I've made some quick tests @ 1'+2", unfortunately Schooner exceeds the time very often.
Hopefully the author implement ponder for the uci-version too.

Most likely that would still exceed the time very often, then.

It would be better to hope he fixes the ponder time management.

If that's true,

I agree.

Have you made any ponder=on tests with Schooner @ Winboard ?

Just noticed this post. The problem as I see it is that UCI protocol requires the engine to submit a ponder move for consideration. Further, the UCI engine is not allowed to ponder the move until the GUI tells it to ponder.

However, Schooner has always pondered positions - not moves. Further, Schooner begins pondering immediately without waiting in xboard mode. These problems are difficult to overcome without a considerable change in code, and change in performance of the engine. If the UCI protocol is tricked into believing the engine is pondering a specific move, then it may crash the GUI. What is the problem with simply using the superior xboard protocol??

Not sure why it is crashing on time. Does this have something to do with ponder, or all types of search?
