My post was not directed at you specifically.

Tiger loses on time probably because the GUI takes between 0.1 and 0.5 second
per move and that the engine is not aware of that.
If the naked engine was playing it would not happen. For example I have never
seen the DOS version losing a game because of this under these conditions.
One simple cure would be to enter a 0.5 second operator time, and it would not
happen anymore, or it would happen after maybe 200 moves.

The final position is interesting when you know that the engine did not know
that for every move it was losing half a second...
If we find out that this player was mostly winning on time by closing the
position and doing nothing until the engine ran out of time, then you can be
sure that with anti-human ON and a 0.5s operator time it will probably not be
the case anymore...
My opinion is: I think that Rebel-Tiger was not correctly configured and that
somebody just took advantage of this. That does not mean that Tiger is
unbeatable, but at least that it is not such an easy client.
