Re. Pressure around bubble deals great solution I experienced at Binions was giving each player a red and black card symbolising deal or no deal and players returned one face down to tournament director a single no and play carried on.
They made it very clear it was to be anonymous and no discussion and although I’m pretty sure everyone knew I was the one dissenter (only non local) the method and attitude of tournament director made it clear there should be no further pressure put on; was great
Even if there are multiple tables left sure each dealer could manage this and as soon as one table has a no play continues. Wouldn’t take many events with there always being at least one no before the practice is wiped out and bubbles just play as they should.
