No, I didn't ( I ran it overnight), and I fully agree that this is a problem
with blitz time controls with no increment.

They two Shredders are currently playing a 30 game match against Deep Sjeng 1.6
at 5'+5" and the current score is:

DS1.6 v S8:               1.0 - 7.0
DS1.6 v Classic1.1:   5.5 - 2.5

Even more interesting! :)
