AI Coach · Range interpretation

How to interpret this CO range

This CO first-in preset is a broad raise-or-fold range with every suited ace raised purely, while its lower edge is selected through raise/fold mixes.

The grid contains no calls: every non-fold action is a raise. Pairs are pure raises from 44 upward, with 33 mixed and 22 folded.

01

Suited ace and king coverage

All suited aces are pure raises, while suited kings are pure from K4s upward; K3s is mixed and K2s folds.

02

Offsuit edge is selective

AKo through ATo, KQo through KTo, and A9o/A8o are pure raises; K9o, T9o, A7o, and A5o are mixed.

03

Connector ladder changes at the bottom

T9s, 98s, 97s, and 87s are pure raises. The grid then mixes 76s, 65s, and 54s, while 75s, 64s, 53s, 43s, and 32s fold.

Drill the four boundaries in order—65s, A5o, Q5s, K9o—then recall the adjacent pure-raise and fold cells for each.
