Slowplaying a 3-6 game with a large pot and the pretty nutty (probable nuts) hand is pointless. Most 3-6 live players have gained one real concept: Pot Odds. If they feel like they have the pot odds, they will draw to the hand (most of them haven't even thought about implied or in this case reverse implied odds). All they will see is that they have a straight draw and the pot warrants a call ("YAY! I get to play!"). Players drawing dead is a HUGE advantage to you, you need to force them to pay when your advantage is at it's largest. Raise, ReRaise and CAP it all the way with a board like this. Hands like these in situations like these don't come around often, you need to make the most of them when they do
