Friday evening IMP pairs in my local club. Board 2. All 13 tables got -480, hence 0.00 IMP for everyone. 12 tables played in 4♥, 1 in 5♥, all by East taking 12 tricks. 10 tables led the ♣J, one led the ♠8 and 2 led the ♥5.
How rare are such hands in a normal club game with a large number of tables, where everyone plays the same contract and gets the same score?
