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
Here is another example of using position to pick up a pot
Here is another example of using position to pick up a pot you would normally never win. Say the stacks are 200BBs, you raise to 3BBs from the cutoff with 9-7o and the big blind, a tight but straightforward player, re-raises to 8BBs. With stacks this deep, if you know how your opponent plays, you can call with basically anything with the intention of picking up the pot on a later street. Say the flop comes A-8-2. If you know your opponent will continuation-bet every time, you should almost always call. Most likely, if your opponent is straightforward, he will check the turn every time he plans to check-fold and will bet every time he has a strong hand, usually something like A-J or better. So, if he checks, bet around 20BBs. You will win the pot a huge percentage of the time. If he bets again, you know he probably hit the ace, so you can just fold.
The other main use of position is to get an extra value bet
The other main use of position is to get an extra value bet out of your hand. Say you raise A-A from the cutoff to 3BBs and the big blind calls. You both have 100BB stacks. It comes K-J-2. You know your opponent will check-raise any time he hits top pair or better, check-call with middle pair and fold all worse hands. When he checks to you, you should bet around 5BBs. Assume he raises to 14BBs. Call here every time and call down unless the board gets very scary. Say the turn is a 3 and he bets 25BBs. Call again. Say the river is a 6 and he checks. This is a great spot to go all-in, as it is very unlikely he has a hand better than top pair, as he would have pushed the river. Since you can now assume he has top pair, a fairly strong hand, you can push, expecting him to be unable to fold it, winning you 100BBs.
