Thanks for all the replies This was a bar tourney, 5 tables. Generally very casual.
While I don’t usually have an issue showing, there was zero potential for collusion, as there wasn’t a side pot to win, and the BB showed the absolute nuts. He was winning the pot, and it was almost instantaneous that he excitedly tabled his top set, and I tossed my losing hand into the muck.
I acknowledge the rule requiring the tabling of hands. The guy was technically in the right to request I show, but his actions were very much an abnormality in this game. To reach into the muck and flip up cards was eyebrow raising to many at the table. He correctly cited the protection against collusion, but as stated, that wasn’t possible in this circumstance. It was an excuse to satiate his curiosity.
