If the engine gives no ponder move the GUI does not try anyway. So far the
hit-rate in games between Suzie and Gnu-Go is low and ponder would not gain
very much.
But once the playing level improves the hit-rate goes up and pondering
becomes very important.

Subject: Re: [computer-go] GTP3 should be UGI
I am a big fan of UCI, and it would be great if we could use a similar
interface for go.
The only part I would probably not try to reproduce for go is the
pondering scheme. In chess assuming the opponent had moved the
predicted move was the most popular choice by far, so it was ok to
have it ingrained in the protocol, but in go this is not the case and
we should probably expect the engine to indicate PV lines that include
the opponent's next move.

Sounds good, but the xboard protocol is also very nice.
Though a UGI sounds like a good step.
