7♣ went for 1400 against 6♠ making. east-west called the fuzz at the end of the board to complain about south bidding on after his partner's hesitant sign off. it's pretty obvious the hesitation suggests bidding on, so is pass an LA?
South would claim his hand guarantees slam opposite the right number of keycards.
east-west would claim that south bidding on with keycard is obviously dirty, as he didn't make another try, and that he could have keycarded over 3S [knowing the pair in question, i would go 100-1 about a direct 4NT being anything other than keycard]. Cueing implies a culsultative role for partner, who he subsequently overruled.
FWIW I wasn't involved. Slam makes on the diamond finesse. Partner's hand is Aktxx x Qjxxx Qx.
Edit: The committee ruled it back to 4S. As this was in the Balkans all sorts of hyperbole ensued.
