Just last night I am playing BBO. Opps vul, us not. RHO (dealer) opens 1H. With 13 hcp and 4 cards in each of the other three suits, I double. LHO passes, partner passes (!) and then RHO sits there for a few moments. I am thinking partner must be sitting on AKQJxxx in hearts, with a spade void, and is planning on setting them bigtime at the one level, and that RHO is either trying to figure out a place to run to or just licking his/her chops at the opportunity to play 1HX vul. Then RHO decides to bid ... 2H.
