ポーカーポジション戦略：完全な初心者のためのガイド

Why Position Matters in Poker

Position is often called the most important factor in poker, and for good reason. When you act last, you have more information than your opponents, which allows you to make better decisions. This information advantage translates directly into profit.

The Poker Table Positions

Early Position (UTG, UTG+1, UTG+2)

Players who act first have the least information about what others will do. From early position, you should play a tight range of premium hands. Opening too wide from early position is one of the most common beginner mistakes.

Middle Position (MP, MP+1)

Middle position players have slightly more information than early position players. You can open a wider range but should still play tighter than late position players.

Late Position (CO, BTN, SB)

Late position is where you generate most of your profit. The button (BTN) is the best position because you act last on every street postflop. The cutoff (CO) is the second-best position.

The Blinds (SB, BB)

The small blind and big blind are the worst positions because you are out of position for the entire hand after the flop. When defending your blinds, consider the cost of losing and play accordingly.
