I had tried Chest with it, but "no mate in 9" needs already an hour, so I stopped to dig deeper. And if it's really a mate in 11, that will take some time for Chest, since the EBF is > 10. I estimate at least 100 hours (4 days), and I'm not going to do it. In case you did not yet... you should send a note to Valentin Albillo about your discovery. May be that causes him to update his pages :-) Cheers, Heiner
