Tournament Strategies
After receiving pocket cards, you are immediately faced with a choice: play your cards and either raise or call the blinds, or fold.
Practice Matters
Suppose on the river you know your opponent’s range
Suppose on the river you know your opponent’s range is made up entirely of missed draws or the nuts. You also know he will never bluff-raise you. You have the nut low, so you can’t win by checking. In this case, your river bluff should be fairly small because he will fold to a 1/3-pot bet with a missed draw and will never fold with the nuts. Obviously most ranges aren’t nearly this polarized, but this should give you the idea.
You should generally not bluff against multiple opponents
You should generally not bluff against multiple opponents on the river, especially if the pot has some chips in it. If you have a busted draw against two opponents, one of them almost certainly has a decent made hand. If you have the made hand, you are better off checking, hoping to get to a cheap showdown. Remember that in multi-way situations, as the pot gets large, you should play your hand more straightforwardly, which means rarely bluffing.
