. For self playing I am using M(T)D AnMon or Wasp. I found out that Benjamin comes from Ed Schröder and wrote ... yes, a program from Ed can't be bad. So Benjamin seems to be good known for grandmasters.

What means M(T)D ??

I love it.

For me, Benjamin is cool, but as far as Ed's work goes, my favs will always be ProDeo with ALEXAL, MACHEID or Storm personalities!
The MACHEID (whatever that name means!) personality is also availabable as a second and next best personailty in Benjamin 2.0, I like it too, less agressive, but more reliable.

Storm is a killer!
Storm is ?, I don't have it, can you post?

EDIT: I also love ProDeo 2.6 and the ability to create your own personalities. I made a few of my own a couple years ago.

Totally, I think MACHEID is sober, but still really aggressive if you give him a chance to be.

As for Storm, I just hooked him up to play in ProDeo 2.2 and here's the first example...

Storm played like a MADMAN and got a winning position and then threw it away with continued recklessness.

Definitely a good opponent for humans. Can you imagine a human getting out of the mess above as Olithink did?

Here is Storm. I wonder what you see here that us mere mortals don't...are those settings sane?
