considering only the last 10 cards - of the stack, can't those be such that the game is unwinnable - without knowing anything else?
example - say the last deal from the stack - is all 8 of the sevens and two kings. wouldn't that be an unwinnable round - independent of any other arrangement of the rest of the cards? each such arrangement, then would be an instance of an unwinnable deal? What am I missing?
