How to interpret this SB vs BTN range

Against the BTN 2.2bb open, this SB preset combines a 3-bet/call core with increasingly selective mixed and folding decisions near the lower pair and offsuit-broadway edges.

The grid shows pure 3-bets at AA–99 except for the listed pure-call ATs and KJs, while many suited aces, suited broadways, and middle pairs mix 3-bet with call. A useful study pattern is that several lower edge hands retain fold shares, and the offsuit broadways shown as mixed never call.

01

Suited ace split

A3s–A8s all mix 3-bet and call, while A9s calls more often than it 3-bets; ATs is a pure call and A2s is a pure fold.

02

Pair ladder

88 mixes mostly toward 3-bet, 77 and 66 mix toward call, and 55–22 each include folding; 44, 33, and 22 have no 3-bet.

03

Broadway action contrast

KQs and QJs mix 3-bet with call, whereas KJo, QJo, KTo, and QTo mix only 3-bet and fold.

Drill three strips from the grid: suited aces from AJs to A3s, pairs from 88 to 22, and the mixed offsuit broadways; recite whether each strip can call before checking the chart.
