Button Open-Raise Range : pourquoi BTN peut jouer le plus large

Short Answer

The button can open the widest preflop range. You usually have postflop position, and only the small blind and big blind remain to act.

Range Logic

BTN can add more suited hands, connectors, weak Ax, Kx, and playable margins. Wide does not mean careless. Tighten when blinds 3-bet aggressively, rake is high, or stacks are shallow.

Sizing

Button opens can often use smaller sizing because position and range width are the main advantages. Small sizing lowers risk versus blinds that fold too much. Against sticky blinds, raise slightly larger and trim weak offsuit hands.

Decision Steps

1. Check both blinds' fold and 3-bet tendencies.
2. Expand with playable marginal hands.
3. Cut weak offsuit hands when rake or aggression is high.
4. When called, use position instead of automatic c-bets.
