The reason I ask is that almost every responder has assumed the player is "reasonable" to some degree. No-one appears to have considered an unknown player may have an unexpected hand.

That said, there are clearly quite a number of "not entirely unreasonable" hands that would play out the same way. I had reasons for choosing this particular hand, one of which was to see what kind of ranges forum-people would put "unknowns" on. It seems some people misunderstood the post, or feel it was not as obvious as I suggested, which is fair comment. However, I still believe that when confronted by an unknown player we need to be prepared for surprises and I for one feel quite reluctant to lay this down here.
