Hi Kai,

yes I found out about the bug too. It happens, whenever Phalanx plays many games
in a row, without beeing restartet - for example in match-game mode in Winboard.
The bug is, that it will stop thinking, it will play it's moves immediately
without using it's time.
Because of this I decided to play all Winboard matches with the flags /-reuse
and /-reuse2. In this way the engines are restarted for every new game, instead
of only starting a new game with the 'new' command using the same engine.
I had no problems with Phalanx since then.

There should be no 'bad' Phalanx games in my results, because I replayed those
first games, in which this phenomenon took place.

And yes, I too think, that Phalanx is very strong, I'm looking forward to
testing version XVIII !

Heiko.
