AI Coach · Range interpretation
How to interpret this SB vs BTN range
Versus a BTN open, this SB preset is centered on 3-bets, with calls appearing only inside mixed cells and many lower suited connectors folding.
The grid has no pure-call cells. Study the contrast between frequently 3-bet suited broadways and aces, and the lower suited connector block that is mostly folded.
Broadway cutoffs are visible
KJs, QJs, and JTs are pure 3-bets; K8s is mostly fold, and QJo is mostly fold while stronger offsuit broadways continue.
Connector treatment is selective
T9s and T8s are mostly 3-bets, whereas 98s, 87s, 76s, 65s, and 54s have little or no 3-bet frequency.
Cover the grid and redraw three zones: suited broadways that 3-bet often, mixed suited aces, and the mostly folded low suited connectors.
