re: Poker & second nuts, early - value raise?
If you want my advice i would need to know the level of play here.
If this is a 1 dollar mtt i'd happily go broke here by raising all in (against an unknown), i do feel we'll get called by many worse flushes by many worse opponents to make it worth it.
If its a reg, or you know the player to be tight from previous history; or if you've seen enough hands to indicate so, such as a vpip of 6 over 20 hands i would agree with the crowd and say just call.
Is anyone ever folding here? Maybe against the worlds biggest nit, where you've seen him pot bet the nuts before??
