AI Coach · Range interpretation
How to interpret this CO vs UTG range
This CO-versus-UTG preset is a compact 10% range built around premium 3-bets, with selective mixes among suited aces, suited kings, and a few broadways.
The grid shows AA, KK, QQ, AKs, and AQo as pure 3-bets, while AQs is the only pure call. A useful study pattern is that lower suited aces often mix 3-bet and fold, whereas only JTs, T9s, 65s, and 54s retain any calling among the listed suited connectors.
Suited-ace contrast
ATs and A7s are strongly 3-bet weighted, while A9s and A4s are more fold-heavy. A8s, A3s, and A2s are pure folds, but A5s and A6s retain mixed 3-bet frequencies.
Broadway separation
KQs, KJs, and KTs mix only 3-bet and call, while QJs and QTs include folding. Among offsuit broadways, AKo, KQo, AJo, and KJo are mixed, whereas QJo, ATo, KTo, QTo, and JTo are pure folds.
Drill four passes from the grid: pure 3-bets and AQs, suited aces, suited kings and broadways, then pairs and the few suited connectors that retain calls; recite each action mix before checking it.
