I do not watch a lot of reality TV (except the first series of the Joe Schmo Show), so I came across this by accident.
During the Gibraltar Masters I often took the same bus to the venue with GM's Ganguly and Shankland. As Ganguly is a regular visitor to the O2C Doeberl Cup, we would often chat, including what post tournament activities were happening. While Ganguly will be in Canberra next month, I just assumed Sam Shankland would be off to another tournament somewhere.
Instead he is taking part in a 'Survivor' style show called 'Kicking and Screaming'. I am assuming this was filmed post Gibraltar, although IMDB does not show the actual filming dates. The series is/was filmed in Fiji as well, so possibly the Fiji Chess Federation might have an inkling.
I have no idea when (or if) the show will be shown in Australia, although based on one review I read, Shankland makes sure he stands out. Possibly he stood out a little too much, as *spoilers* he has been voted out in the latest episode. Of course these show do bring people back, so he may pop up in a future episode.
