E/W play strong club
1♥ = 5+ cards, 11-15
2♣ = GF relay (Ice-relay)
East's pass = 3♠s +5♥s
4♥ = minimum, no interest
4♥ is after very long hesitation (1min+)
Pass instead of 4♥ would have been further relay (minor distr.) 4♦ would show some slam interest (E bids 4♥ if not interested). I assume other bids (like the seemingly obvious 3♠) would be natural or Cue aggreeing .
N/S complained on the grounds that Pass was a logical alternative to 5♣ etc. How would you rule as TD? If the ruling (score stands or +480) were appealed what would you rule as AC?
