There were some very unfortunate coincidences here.

The best improvements I made lately in XiniX were taking out a lot of bugs.
Unfortunately in the first 4 rounds I used my last compile wich was a debug
version. This version is about 2 times slower than the release version, but
because I just got my new computer wich is 6 times faster I didn't notice.

A side-effect of my debugversion is that it basicly disables my egtb's,
returning always a draw.

So in this position XiniX said draw, Sjeng said white wins. With 2 minutes on
the clock, Sjeng allocated 20 secs for his move, wich lead me to believe that
Sjengs score was an evaluation score so XiniX' score was correct.

I was waiting for my opponent to offer the draw, wich I thought ( because of the
time difference ) I did not have to offer.

He didn't and lost on time.
