Preflop Chart

Button opening range

The button acts last on every street after the flop and only has the two blinds left to beat, so it opens the widest range in the chart. Beyond the cutoff range it adds the steal tier: suited kings down to K5s, Q8s, suited one-gappers like 86s and 75s, and offsuit hands such as A8o, K9o, and T9o.
