Starting Hand

How to Play A5s — Ace-Five suited Preflop Strategy

A5s is a premium starting hand: GTO opens it first-in from all 5 positions in a 6-max cash game, and it stays in the shoving range down to the shortest stacks. It's a raise-or-shove hand — never a fold first-in. In numbers: it opens 100% from every seat, button and lojack alike; at 15bb it is a first-in shove from 5 of 7 seats; heads-up against AA it has 13.4% equity.

Playing A5s preflop

A premium hand — open it first-in from every position. As stacks get short it only gets stronger — at 5bb A5s is a jam from essentially every seat.

A5s opens from every seat — it's strong enough to raise even under the gun (LoJack), where you have the whole table left to act behind you. Position doesn't change the decision here: it's an open everywhere.

The common mistake with A5s is playing it too passively — slow-playing or flat-calling when the solver simply raises it for value from every seat. Open it, and be ready to get the money in.
