The grid gives a memorable default for common preflop spots. Opening ranges follow widely taught
100 bb 6-max conventions; responses to raises and limpers are intentionally simplified so a learner can
act without memorising hundreds of solver mixes.
01Use the big actionIf one action dominates, learn that first. Tiny mixes matter far less at a real table.
02Respect positionLater seats can play more hands because fewer players remain and you act later postflop.
03Adjust with evidenceExploit a stable tendency. “Fold-happy” adds pressure; “call-happy” removes thin bluffs.
“Always” is rare in poker. A recommendation here is a training baseline, not a guarantee of profit.
