Jump Scare by Foxymoron

 The jump scare is a technique in horror films causing the audience to suddenly sit up and take notice. It featured in Friday the Thirteenth, and was notable in Carrie. Drag Me to Hell was criticised for overusing the technique.

Bill Linton, East on the hand below, tried the technique tonight after a horror auction. He had misclicked on 2D instead of 2H at his first turn and was now trying to make amends. He jumped to Six Hearts hoping to scare Andy Clery into passing. But no such luck. Andy had three diamonds and no hearts and gave preference at the seven level. North unsportingly doubled and that was no matchpoints for EW.

What should Six Hearts actually mean? AQxx Ax AKQJxxx none springs to mind. Partner is given a choice between 6S, 6NT, 7S or 7D. It probably has a void, as it has not gone more slowly. Of course, all this is conjecture as the bid cannot exist. What would I bid on the West hand? I think 6NT. I have both black suits stopped and this cannot score badly even if makes an overtrick.

So the difference between bidding 6NT and 7D was all the matchpoints. I think 7D must be wrong, whatever partner has. Your diamond support cannot be worse, 6NT on a spade lead is interesting, You win with the ace, drive out the heart and then guess whether to take the diamond or club finesse. Cash the top clubs first, I think, if you can.

Of course, one cannot bid sensibly on the assumption that partner has misclicked.  It is very hard to recover from bidding 2D on the East hand, particularly as online bridge generally does not allow even "mouse errors" to be corrected. And you certainly cannot tell the table that you have misbid. That would be illegal.
