Since I have the data, Chest said after 2206 seconds that there was no mate in
11, here are the first lines of the statistics:
time
# 3 0.00 1.00 0- 0
# 4 0.16 1.21 478- 0
# 5 0.55 1.49 1932- 0
# 6 1.54 1.98 8618- 0
# 7 5.05 2.59 32559- 0
# 8 18.19 3.47 132676- 0
# 9 62.01 4.63 490166- 0
# 10 269.63 5.02 2352078- 7667
# 11 2206.19 5.02 20500527- 15913024
This was on my work pc (a p3/933), I'll leave it to Heiner to report the mate.

Must be nice if you can understand so many languages ... I'm still trying to
slowly catch on to Italian, since we have Rai Uno back on cable tv since a
month, but boy do Italians talk fast! :)
The moment I recognize a couple of words and have understood them, they are
already 3 sentences ahead of me. Well, maybe I'm just slow ... ;)
