Comment les ranges préflop se resserrent par position : UTG à BTN

Short Answer

Preflop opening ranges widen from UTG to BTN because later positions have more information, better postflop position, and less risk from players behind. Early positions need raw strength. Late positions can add more marginal but playable hands.

Why Position Controls Range

When UTG opens, many players remain behind and medium hands can face strong 3-bets or multiway pots. When BTN opens, only the blinds remain and BTN keeps last action postflop. The same hand can be profitable on the button and losing under the gun.

Practical Framework

1. Early position: prioritize high pairs, strong aces, and strong suited broadways.
2. Middle position: add more medium pairs, suited connectors, and strong suited broadways.
3. Cutoff: expand with suited aces, suited connectors, and some offsuit broadways.
4. Button: play the widest range, but still account for blind 3-bet frequency and rake.

Common Mistakes

The biggest mistake is moving profitable BTN hands into UTG. Another mistake is judging only starting-hand strength while ignoring realization. Small suited connectors gain value with depth and position but can become losing opens from early position.
