Board 5. This is a genuine question. Having taken the finesse in spades, is there any reason to prefer or reject returning to table to lead the Q and pin the 10 rather than playing to drop the K8 in RHO's hand? I would rule out RHO having K108x because even the robot wouldn't play the 8 on the first round of trumps (they can see dummy). It seems to me that the chances are even, so this is where you can tell me that I'm wrong, and would therefore prefer to try the Q of table because when it succeeds it's very annoying for the opponents and I'm not a very nice person.
