Yes.

Not the normal version. I was testing a version with many extensions and checks
in quiescence which performed very well in solving tactical test suites. That
version clearly outperformed some of the commercial engines (Tiger included) in
fast time controls (on my slow hardware I have to mention), but the results were
far from satisfying in longer time controls...
