How far off an opening bid does it have to be before it's a serious error ? I evaluate that hand as a 10 count which is a mile off a 1N opener, K&R is slightly more generous but still reckons less than 11.
Now imagine with everybody known to hold 3 hearts at trick 11 declarer has Q10x opposite xxx, with the hand over the Q having opened 1N and each opp having shown up with 5 points, so he leads up and plays the Q and of course loses to the obvious AKx. I wouldn't expect him to get that back, but I consider this one just as ridiculous a piece of play (although it won't matter a lot of the time as the NT opener will have KQ tight left).
