Positions and initiative

Two players are dealt the same hand, same cards, same stack. One is on the button, the other is first to act. Their long-term results won't be the same. What changes is when they act. This lesson explains why, and how you use it from preflop on.

The six positions at 6-max

With 6 players, there are six seats. In preflop order of action:

After the flop, the order changes: the SB acts first, then the BB, then the others in order, and the BTN always acts last. UTG and HJ are often grouped as early position, the CO and BTN as late position, and the two blinds as the blinds.

Why position is worth money

Acting last gives you three advantages, and they apply on every street.

1. Information. You see what your opponent does before you decide. If he checks, you learn he's probably weak. If he bets, you know what you're facing. He has nothing like that on you.
2. Pot control. With a medium-strength hand, you can check behind and take a free card, or bet to build the pot when you're strong. Out of position, you have to decide without knowing whether your opponent will raise.
3. The last word. When your opponent checks, you can attack a pot nobody wants, with a hand that wouldn't win at showdown.

A concrete example, from the lab's exercise series: in the BB, facing a button open of 2.5 bb with the small blind folded, the pot odds calculation gives a required equity of 27.3%. Yet you won't realize all of that equity, because you act first after the flop and will sometimes have to fold the best hand. Position acts like an invisible tax on the hand that calls out of position.

Preflop initiative

Initiative means being the last player to bet or raise preflop. The player who opened (raised) and wasn't re-raised has the initiative on the flop.

It gives you the natural right to bet first (the c-bet), with two weapons: the strong hands you hold, and the bluffs your opponent has to fear, since your opening range contains more high pairs and strong cards than that of someone who just called.

Position and initiative reinforce each other: opening from the button means opening with the initiative and acting last after the flop if the blinds call. It's the most comfortable combination in the game.

What this changes about opening range width

An opening range is the set of hands you open (raise) with in a spot. It gets wider as you get closer to the button, for two reasons:

• Fewer players behind. On the BTN, only two blinds are left to get through; from UTG, five players can still wake up with a big hand. Less risk of running into something stronger.
• Position after the flop. Every hand becomes more profitable when you act last, including the more modest ones.

In words: tighter early, wider on the button. So you can feel the gap without copying a chart, here are two illustrative ranges (not charts to play):

• A tight early-position range, 77+, ATs+, KQs, AQo+: 92 combos.
• A wide button range, 22+, A2s+, K8s+, Q9s+, J9s+, T9s, 98s, 87s, A8o+, KTo+, QJo: 298 combos.

The second contains far more hands than the first.

Common mistakes

• Opening too wide from UTG. This is the most frequent leak. Hands opened from early position get dominated by the hands that call or re-raise behind you, and you play out of position against up to five possible opponents. When you hesitate over a marginal hand from UTG, fold.
• Defending too little in the BB. You've already invested your blind, and facing a button open (small blind folded) your price is good: you need 27.3% equity to call 1.5 bb and aim for a final pot of 5.5 bb. Folding almost always leaves your blind's money behind every orbit. Defending wide doesn't mean defending everything: the weakest hands fold despite the price.
• Playing hands out of position as if they were in position. A call from the BB isn't worth the same as a call from the button with the same hand.
• Opening with a hand that has no plan. If you have no idea what you'll do after a call or a re-raise, it probably doesn't belong in your range from that position.

Key points

• Acting last gives information, pot control and the last word: position is worth money, on every hand.
• Preflop initiative lets you bet first on the flop. Combined with position, it makes the button the best seat in the game.
• Tighter early, wider on the button, and defend widely in the BB without defending every hand.

Practice
