How to interpret this CO vs MP range
This CO-versus-MP open preset is a compact 3-bet-led range with no pure calls.
The grid 3-bets premium pairs, strong broadways, and selected suited aces, while every displayed call appears inside a mixed cell. A useful study pattern is that several low suited aces show more 3-bet than the listed suited connectors and small pairs.
Broadways concentrate in 3-bets
KQs, KJs, KTs, QJs, and QTs have more 3-bet than call and no fold branch. KQo mixes all three actions, while AJo mixes 3-bet and fold only.
Connectors are mostly fold branches
T9s, 98s, 87s, 76s, and 65s all display more fold than either continuation action. Among the listed suited connectors, 54s has the largest displayed 3-bet branch.
Recite the 3-bet-heavy ace, broadway, and pair cells first, then test the mixed call and fold branches.
