How to interpret this CO vs UTG 4-bet range

This CO-vs-UTG 4-bet preset is very narrow, with 5-bets appearing only in AA, KK, QQ, AKo, and AKs mixes.

Below the strongest pairs, the grid is largely call/fold, with selected suited aces and suited kings continuing. AKo is the only offsuit hand shown as continuing.

01

Top-pair split

KK is 5-bet-heavy, AA calls more often than it 5-bets, and QQ is mainly a call with some 5-bets.

02

Ace contrast

AQs, AJs, ATs, and A5s are call/fold mixes with no 5-bets, while AKs is a 5-bet/fold mix with no call.

03

Narrow lower edge

KQs and KJs retain calls, while T9s, 87s, 76s, 65s, and 54s are call/fold mixes; 44, 33, and 22 are pure folds.

Memorize three tiers: 5-bet-capable hands, suited call/fold hands, then the thin connector and pair tail.
