AI Coach · Range interpretation
How to interpret this BB vs CO range
This BB-vs-CO preset is more selective, with a compact pure 3-bet group and a broad mixed calling layer.
The grid shows strong pairs and broadways in the pure 3-bet group, then many suited aces, suited kings, and connectors split between 3-bet and call. Across several connector pairs, the suited version continues without folding while the offsuit version includes fold.
Suited king bands
KJs leans to 3-bet; KTs and K9s are near-even mixes; K6s and K4s lean to call. K8s, K7s, K5s, K3s, and K2s are pure calls.
Connector contrast
76s leans to 3-bet and 54s is near even, while 76o and 54o mix call with fold. 97s, 96s, and 95s are pure calls.
Compare each suited connector with its offsuit counterpart, then separately rehearse A5s, KTs, K9s, 76s, and 54s as mixed anchors.
