How to interpret this BTN vs CO 4-bet range

This BTN vs CO 4-bet preset is a narrow continuation range centered on calls, with selective 5-bet mixes at the top.

The grid keeps several suited broadways and medium-to-high pairs through calls, while 5-bets appear mainly among premium pairs and AK. A useful study pattern is the uneven suited-ace region, especially the call-heavy A5s beside many folding suited aces.

01

Premium pair mixes

AA and KK use 5-bets often, while QQ and JJ use all three actions rather than a single action.

02

Suited ace contrast

A5s is mostly a call; AJs and ATs also call often, while A9s and A4s call rarely and A8s through A6s are pure folds.

03

Connector edge

JTs is a call/fold mix, T9s calls less often, and 87s and 76s continue only rarely; 54s is also a call/fold mix.

Recite the call-focused groups—AQs, AJs–ATs, A5s, KQs–KTs, and TT–66—then test yourself on the exceptions A9s, A4s, JTs, and 54s.
