I think it was not wise to abandon cgos.boardspace.net (the
domain-name). It is also unfortunate that no e-mail address of the
engines playing on it are known (afaik).

There's two (well, 3 really) versions running of my own experiment,
together with "brown" (a random player).

For fun I added monte-carlo to my go-program and even with 7 (seven)
playouts per second it is already winning from the non-monte-carlo
version. Not what I was expecting: I thought this would require tens,
maybe even hundreds of playouts.

That would explain it indeed.
