No screens in effect, when north bids 3♥ south alerts and explains that 3♥ asks for a heart stopper, then he bids 4♠.
Later NS will show a written defence where it says 3♥ actually asks for heart stopper and is no kind of 2 suiter.
South was played the hand perfectly making club finese and running clubs without touching trumps being one of the very few to make the contract. Guess this actually has nothing to do with a previous ruling against him, but just in case.
Anything to rule?
