The way CB GUI handle pondering for Winboard engines that not spesific say that
they are CB compatible (e.g. implemented ponder command) is:

1.CB tourn off ponder with hard+easy

2.When it receives a PV line it allways save the last opponent move (move 2).

3.Now when the engine do a move CB do the move on the board and send a new game
to the engine with this saved PV move as opponent move and let the engine think
that it is his time again.

4.If the opponent do the expected move CB let the enging proceed with his
thinking. If opponent didn't do the expected move it send the engine the a new
game with this new move and let the engine think on this position.

With newer adapter than the one from nov.2000 this hard+easy command is 'buggy'
so be sure to use the adapter from Chessbase's site.

There have also been opserved that the move CB send the engine as 'ponder' move
isn't allways the from the last pv-line.

As you can see this would let (weaker) engines that have not any ponder feature
play a little better but top engines that would like to take care of this
themself isn't allowed to do that.
It will also heart the engine a little if the opponent use longer time to make
the expected move.
