Playing 4-bet pots after the flop

In a 4-bet pot most of the money is already in before the flop. With 100bb stacks, a called 4-bet usually leaves an SPR under 2: around 45–50bb in the pot and about 75bb behind. Post-flop play becomes simple: with any decent hand you’re committed; with nothing, you check or make one small bet.

Why it’s simple

At SPR 1–2, folding a pair after putting in a quarter of your stack is rarely right. The pot is giving you great odds. That’s why most players 4-bet only strong hands at low stakes. See 4-bet and SPR.

As the 4-bettor

You usually hold A-A, K-K, Q-Q, A-K.
With a pair or overpair: bet small (about 1/4–1/3 pot) or just get it in. Don’t slow down; there’s nothing to protect.
With A-K that missed: one small c-bet on dry high boards; on low connected boards, check and decide. With overcards and a gutshot or backdoor draw at SPR 1, calling a shove is often fine.

As the caller

If you called a 4-bet, you probably have Q-Q, J-J, A-K or A-Q suited.
Top pair or an overpair: get it in.
Missed completely on a low board with A-K: check and fold to a big bet only if the stacks are still deep enough; otherwise your two overcards often have the odds to call.
