Matchpoints, ACBL robot individual

If you open the South hand 1♠ and pass East's reopening double, you'll be left to play there and score -300 or -500.

If you open the South hand 2♠ and pass the reopening double, you'll be left to play there as well.

If, however, you open the South hand 1♠ and rebid 2♠ over the reopening double, you create this surreal masterpiece.

I can't imagine that a double by West would be for take-out in this position, but obviously the robot wasn't prepared for this bid. I'm going to add this to my arsenal, along with the psyche redouble that also worked in this position (not as well, but it did work).

Good point, I have seen this several times. Should be addressed by BBO. Mind you I wouldn't try it, since W doesn't always have a penalty pass and you are likely to get in trouble in another way.
