This is a discussion on How do you play with Big pairs within the online poker forums, in the Learning Poker section; Lately, I've stopped eating with a big hand. What is better? If you have any advice, please let me know.
Short stack is the time to go all in. A pair wins most of the time in poker and this the ideal time to play in a way that is +ev and already has showdown value. This is short stack, so you need to play push/fold to build a pot.
Medium stack is the time (which many will argue against) to get to the flop at a decently cheap price. You raise 3xbb and hope someone is not about 3 bet all in. Play smart aggression and you can bank with them.
Deep stack is the time to bet heavily if you want to keep away the garbage hands. You can afford to bully the table at this point. Play smart and the chips will come.
