AI Coach · Range interpretation
How to interpret this BB vs CO range
This 40bb BB vs CO open preset combines a pure 3-bet core from 99+ and strong aces with an extensive calling range, especially in suited holdings and lower pairs.
The grid shows AA, KK, QQ, JJ, TT, 99, AKs, AQs, AKo, and AQo as pure 3-bets, while 77–22 call purely except for 88, which mixes 3-bet and call. A useful study pattern is the uneven mixed region across suited broadways, offsuit broadways, and offsuit aces.
Offsuit aces use different action pairs
A9o is 3-bet/call, A7o is call/fold, A6o and A3o are 3-bet/fold, A5o is 3-bet/call, and A4o uses all three actions.
Suited connectors remain calls
T9s, 98s, 87s, 76s, 65s, and 54s are pure calls; nearby offsuit connectors such as T9o, 98o, 87o, 76o, 65o, and 54o also call purely.
Drill the grid in four passes: pure 3-bets, pure calls by pair and suited rows, mixed suited broadways, then mixed offsuit aces and broadways.
