Preflop Tournament Strategy: Ranges by Position
Preflop tournament strategy: opening ranges by position, sizing, and how to tighten or widen as stacks shrink and antes kick in. With a worked example.
On this page · 6 sections
Winning preflop tournament strategy comes down to three levers: which hands you open by position, how much you raise, and how those choices shift as stacks shrink and antes appear. Get those right and most of your postflop spots become easy; get them wrong and you leak chips before a flop is ever dealt. The default plan is to raise-or-fold — rarely limp, rarely cold-call — while opening tighter early and much wider on the button.
Open-raising ranges by position
Position is the strongest single factor in what you should open. The later you act, the fewer players remain behind to wake up with a hand, and the more often you hold position after the flop. That lets you profitably open far wider from the cutoff and button than from under the gun.
| Position (9-handed) | Approx. opening range | Example hands |
|---|---|---|
| UTG / early | 10–15% | {AA-77, AK-AJ, KQ}, some suited aces |
| Middle (MP/LJ) | 15–20% | add smaller pairs, {ATs, KJ, QJs} |
| Hijack | 20–28% | add suited connectors, {KTs, A9s} |
| Cutoff | 28–40% | add most suited broadways, weaker aces |
| Button | 40–55% | any pair, most suited hands, many offsuit aces/kings |
| Small blind | 25–40% | raise (don’t limp) into the big blind |
These are guidelines for a roughly 40+ big blind stack. Shorten the stack and the ranges shift — see the stack-depth section below.
Raise sizing
Once antes are in play, use a small open of about 2 to 2.5 big blinds. The antes already build the pot, so a small raise risks fewer chips to win the same dead money, which improves the price on your steals. Before antes, or when very deep, 2.5 to 3x is fine. Avoid the common mistake of opening large “to get value” — big sizing doesn’t fold out many more hands, it just costs you more when you’re stealing and gets called by worse anyway. Consistency matters too: use the same size with your whole range so you don’t telegraph strength.
Adjusting for stack depth
Preflop ranges are not fixed — they slide with your stack:
- Deep (50bb+): Play more suited connectors, suited gappers, and small pairs. These hands flop well and their implied odds are highest when stacks are deep. Cold-calling in position becomes more defensible.
- Medium (25–40bb): Standard opening ranges above. Start folding the weakest speculative hands out of position; 3-betting replaces flat-calling more often.
- Short (15–25bb): Tighten offsuit trash, lean on 3-bet shoves rather than 3-bet-then-fold, and stop cold-calling opens out of position.
- Push-fold (under ~12bb): Ranges collapse into shove-or-fold. Charts here are near-solved — study the short-stack push-fold guide.
Facing a raise: 3-bet, call, or fold
When someone opens in front of you, default to 3-bet or fold more than flat-calling, particularly out of position. Flatting is best in position with hands that flop well and dominate the caller’s range. For value hands and bluffs with fold equity, re-raising takes the initiative and denies cheap flops — the mechanics of building those re-raise ranges are covered in the 3-bet and 4-bet guide.

Worked example: button open with antes
Blinds are 500/1,000 with a 1,000 big-blind ante. That’s 500 + 1,000 + 1,000 = 2,500 chips already in the pot before anyone acts. You’re on the button with A♣ 7♣ and everyone folds to you. You have 40,000 chips (40bb).
A♣7♣ is a clear open here: suited, an ace blocker, and you’ll have position postflop. Raise to 2.5bb = 2,500. If both blinds fold, you win the 2,500 in the pot risking 2,500 — a break-even price on the steal by itself. But you also have a hand that can continue profitably when called and a positional edge on later streets, so the true expectation is comfortably positive. This is why the button opens the widest range at the table: the combination of dead antes, position, and only two players left to act makes marginal hands profitable that would be folds from early position.
Bottom line
Solid preflop play in tournaments is mostly discipline: open the right range for your seat, use a small consistent size once antes arrive, favor raising over limping and calling, and tighten or widen as your stack changes. Nail those fundamentals and the rest of your tournament game gets dramatically easier.

Frequently asked
How should I play preflop in a poker tournament?
Open-raise a range that tightens in early position and widens in late position, use a small sizing (around 2 to 2.5 big blinds once antes are in play), and adjust for stack depth. Deep, you can play more speculative hands that flop well; short, you shift toward push-fold. The single biggest preflop leak is limping and cold-calling too much instead of raising or folding.
What is a good opening range in tournaments?
Under the gun at a full table, open roughly the top 10 to 15 percent of hands: big pairs, strong aces, and premium broadways. From the cutoff and button that widens dramatically, to around 25 to 45 percent, because you have position and fewer players left to act. The button is the most profitable seat and should open by far the widest.
What raise size should I use preflop?
Once antes are active, a small open of 2 to 2.5 big blinds is standard because the antes already sweeten the pot, so you risk less to win more. Preante or very deep you might use 2.5 to 3x. Larger sizing wastes chips and gives worse odds to your own steals without meaningfully changing how often you get called.
Should I limp in poker tournaments?
Almost never as a strategy. Open-limping lets opponents see cheap flops and surrenders the initiative you get by raising. The rare exceptions are very deep-stacked spots with a specific plan, or an over-limp behind other limpers with a hand that flops well. Otherwise, raise or fold.
