HEY!!! THIS IS BBF! DBL FOR PENALTY IS FORBIDDEN AND MUST BE TAKEOUT <_< besides you never, ever hold 4 of the opps trumps including the AQT :) You overstate things. In a simulation opposite a 12-14 hcp 1NT and with your RHO opponent having five spades and 11-15 hcp or perhaps a little less strength with six spades ... 1087 times out of 1000000 you had ♠AQTx. Actually I was generous to you and counted hands where the x was the jack or king and hands where you had five or more spades. I am sure that there are much more frequent uses for double, the most economical positive call, that would prove much more useful than a penalty double in this auction. if you have no easy way to penalize the opponents you are inviting them to steal from you and they will.
