Default Monte Carlo for Go

There was a recent article about using Monte Carlo for computer Go, where,
as I understand it, the evaluation of a potential move is based on the
percentage of wins in a large number of continuations of the game starting
at the current position and making randomly generated moves. Either that or
using the resulting percentages to trim the tree and decide which moves to
focus more evaluation on. A fast computer is able to do tens of thousands
per second of simulated Monte Carlo games from the current position.
Supposedly it's resulting in an advance in the quality of computer Go. Has
that ever been tried for chess? Sounds interesting.

The Chessbase version of Rybka 3 includes a Monte Carlo analysis
feature. AFAIK, it's not a feature of the engine itself, but of the
Chessbase GUI that's sold with the Chessbase version of Rybka 3.
