Subject: Testposition King Safety ( or maybe something else)

Just came across this one:

[D] 7r/Q2k1ppp/2b1p3/8/6q1/2B5/5PPP/2R3K1 b - - 0 1 am Ke8

Here black has to play Kd6 and this should take not much time. Ke8 loses without
any resistance.

Very interesting differences between the engines . For example Fritz solves this
in 0 seconds and Yace and many others will need several _minutes_. In general
this one seems to be very tough for the amateurs . Shredder has a hard time,
too.

This is move 27 out of an ICC blitz game :
