Texas Hold'em Tournament Scenario: One or more players have moved all-in while two or more players still have chips. Additional community cards to come.
This is one of the few scenarios I play the same way every time. I check it down...unless, of course, I end up with the nuts. This play maximizes the chances for the all-in(s) to lose, which gets you closer to the money. This is the correct play. It is how I recommend you play.
What I find interesting is how other players react to a breach in this well-known strategy. I have heard more people break into condescending lectures of how to play, or not-play in this case, that can domino into a full-on tirade the likes of which I thought only Christian Bale was capable. Not cool.
I try not to stand in the way of bad play when I stand a chance at profiting from it. Beyond alerting the few of you who might not have known the above strategy, my tip of the day is this: Size up your opponent in times like this. If someone you perceive as a good player bets into you and over all-ins, take him at his word and fold. He likely knows the strategy and has a monster that he wants to maximize. If you perceive the opponent as inexperienced, play as you normally would and adjust for the all-ins by sticking with reasonable draws.
