Ultrafast UCI engines tournaments : a freeware tool

[bob]

I've seen the same. James and I discussed this on our way to
UAB last October.

A partial list of parameters that can easily look good at blitz but bad
at long time control:

• King Safety tunings
  Passed Pawn tunings
  Search parameters

Basically, anything that makes it more aggressive tends to perform
better at bullet and fast blitz than at long TC's.

That is why I run both blitz and long TC testing on new versions.

I perceive extremely fast TC's as good for crash testing.

my sentiments exactly. I call this a "crafty stress test" and sometimes play a game at a rate of 1,000 moves in 1 second, to see if anything breaks. Tests the protocol, parallel search, everything, in a very hectic way...
