I wouldn't be entirely convinced that any contestants who had ideas about where they thought the big money was, in the original run of the show, would have played on as if still in live play either, to be honest! And why would they? If you've dealt, and you reckon the big number is in box 11, of course you're going to select number 11...I know we're British and we love a bit of gentleman's-agreement-unspoken-rule-following, but I find it difficult to believe that even a majority of players who dealt were not actively seeking the higher amounts in the proveout rounds. As humans, we are literally wired to do whatever we believe to be best for ourselves! (Within reason, of course).
Anyway, what a great game. This was the first in-play offer that I've seen and thought was actually fair for the board. A sign of things to come, one hopes!
