Well, mine is certainly even slower than yours on this position. My old settings
found the following on my p3/1000:

03:49 WM13 09 Qxc7+ Qxc7 Nde7+ Qexe7 Nxe7+ Qfxe7 Qgg4+ Be6 Qxe6+ Qxe6 Bd7+ Qcxd7
Rxc5+ Qec6 Rxb8+ Qxb8 Qxd7+ Rxd7 Qa6+ Qb7 Rxh8+ Rd8 Rxc6+ Kd7 Qxb7#

Then I checked my new settings, and they showed this:

07:34 WM12 10 Qxc7+ Qxc7 Nde7+ Qexe7 Nxe7+ Qfxe7 Qgg4+ Be6 Qxe6+ Qxe6 Bd7+ Qexd7
Qxd7+ Qxd7 Rxc5+ Qdc6 Rxc6+ Qxc6 Rxb8+ Kd7 Qa7+ Qb7 Qxb7#

So a shorter mate in a longer time. It seems mine likes positions where the
pieces are closer together better ... this one's too spacey ... ;)

Oh, and if I am more restrictive in trying attacking moves (like I explained
last week) the time goes down a bit here, but Pretz still needs 2 minutes for
the mate in 12 ... and actually I don't like this way of speeding up!

By the way ... what is the name of the above Chinese character, and what does it
mean? Couldn't find it on the web this time.

Groetjes,
