AI Coach · Range interpretation
CO first-in is a broad raise-first range whose fringe is defined by selective offsuit, suited-connector, and low-pair opens.
Every played hand raises; the only mixes are raise/fold decisions at the edge. The grid keeps a wide suited core while making different choices among marginal offsuit hands, suited connectors, and small pairs.
All suited aces and many suited kings are pure raises, while K3s and Q5s are mixed and nearby low suited holdings fold.
A8o is almost always raised, but A5o, T9o, K9o, and J9o are mixed at very different frequencies.
33 and 22 are mixed opens, while 86s, 65s, and 54s are mostly raised despite several nearby suited connectors folding.
Trace the raise frontier: memorize the mixed suited exceptions, then the five mixed offsuit rows, then the low-pair and connector exceptions.
