Please set the WB2UCI option to ponder=false. Pondering in Winboard and UCI is different.
In UCI, the UI tells the engine what to ponder on. The UI uses the PV output from the engine to figure out what move the engine should ponder on.
In Winboard, the engine decides for itself what to ponder on. It maybe from the previous PV, or it may be from a shallow search.

alright. I hope that was not the cause of the problem.

Hi Lance,
Since you don't print evals, PVs, nodes, nps...
how can I compare the speed of the 64-bit version against the 32-bit?
When will you give the possibility of infinite analysis (and printing something
)?

Thinker 51D 'passive' - Spike 1.2Turin +12 =10 -12
Lots of great games!
thinkerspike.pgn - 0.19MB
However, games 29 and 30 had the bug
Lance, the wb2uci log file:
wb2uci.log - 3.71MB

The problem is with WB2UCI. All those bad moves are coming from WB2UI. It was not even instructing the Thinker engine about the state of the game.
After WB2UCI sent all the opening moves to the Thinker engine, it started producing its own moves. The first time that Thinker made a move, WB2UCI did not even send it to the Fritz UI.
I think WB2UCI gets confused when it received "0-1 {Black wins}" from the previous game, and it now thinks that the Thinker engine has stopped also.
This problem will always happen if the previous game ended in a state where the Thinker engine knows what the outcome is and sends the result to the UI. It looks like WB2UCI now thinks that the engine is stopped, even in the next game.

Glad it's solved
Great to confirm that it wasn't your engine, too. I understand there are other wb2uci? Maybe recommend a different one? The one I've been using is from the rybka thread posted by vytron (is that you Lance?)

Have a read there. It should help answer some of your questions.

But WB2UCI only does this with the Thinker engine?

I can easily run the Ubuntu 8.04 + WINE + Winboard + Thinker combination without any special configuration (everything right out of the box).
If your WINE config won't run Winboard, neither would Thinker run on it.

Hmn, I think I now understand why. Looking at the WB2UCI log again, it looks like Thinker and WB2UCI are exchanging messages about the result back and forth.
I'll do another "quick fix" to detect this condition. It should be out tonight.
