AI Coach · Range interpretation
How to interpret this CO vs MP range
This CO-versus-MP preset is a compact 3-bet-heavy range with calls appearing only in selected mixed suited aces, broadways, and pairs.
The pure 3-bet core is AA, KK, QQ, JJ, AKs, A6s, and AQo. A useful study pattern is the non-linear suited-ace map alongside increasingly fold-heavy lower pairs and suited connectors.
Broadway ladder
AQs through ATs and KQs through KTs mix 3-bet and call. QJs and QTs are strongly 3-bet weighted, whereas JTs includes 3-bet, call, and fold.
Pair and connector floor
TT and 99 mix only 3-bet and call, while 88 uses all three actions. Below that, 77 and 66 are fold-heavy, and 65s, 54s, 55, 44, and 33 are almost entirely folded with only small call components where shown.
Drill the grid in three passes: recite the suited-A exceptions, then the suited-broadway ladder through JTs, then the pair ladder from TT to 33; for each mixed cell, name its available actions.
