Stealing the Blinds and Antes in Tournaments
Why antes make stealing so valuable in tournaments, how wide to open from late position, the right open sizes and how to handle stacks and players behind you.
By PokerLevelUp Team,
Once antes kick in, every orbit costs you real chips — and every pot starts with something worth fighting for. Stealing that pot before the flop is one of the most important sources of chips in a tournament. Players who steal well keep their stacks healthy without needing premium hands; players who wait for aces slowly bleed away. This lesson shows you how often to steal, how much to raise, and when to hold back.
Key takeaways
- With a big blind ante, the pot is 2.5bb before anyone acts.
- A 2bb steal needs to work only about 44% of the time to break even — before counting your equity when called.
- Open wider from the cutoff, button and small blind; tighten when strong or short stacks are behind.
- Use small opens (2–2.2bb) in tournaments with antes.
- Pay attention to stacks behind you: short stacks re-shove, big stacks call.
The maths of a steal
With a big blind ante, the pot before anyone acts is 2.5bb (0.5 + 1 + 1). If you open to 2bb from the button and everyone folds, you win 2.5bb. If they don’t fold, you lose your 2bb (in the worst case, ignoring the times you win after the flop).
Break-even fold rate = risk ÷ (risk + reward) = 2 ÷ (2 + 2.5) ≈ 44%
In reality you do better than that, because when you’re called you still have equity and position. That’s why so many hands become profitable steals once antes are in play.
Compare it with no antes: risking 2bb to win 1.5bb needs folds 57% of the time. The ante makes stealing far more attractive.
How wide to steal
A rough guide for 30–50bb stacks with a big blind ante, when it’s folded to you:
| Seat | Opening range (approx.) |
|---|---|
| Early position | 15–18% |
| Hijack | 20–24% |
| Cutoff | 27–32% |
| Button | 40–50% |
| Small blind (vs BB only) | 40–60%, often with a mix of raises and limps |
These ranges are wider than the cash-game ranges from the core course, because the pot is bigger. Start with them and adjust to the players behind you.

Open sizes
- 2–2.2bb is standard in tournaments with antes. It risks less when you’re re-shoved on and gives the same fold equity against most players.
- Deep stacks (60bb+) can use 2.2–2.5bb.
- Short stacks (below about 15bb) should mostly shove or fold rather than open small — see Push-Fold Charts.
Look at who’s behind you
Your steal succeeds or fails because of the players still to act. Check them every time:
| Player behind you | Adjustment |
|---|---|
| Tight, folds a lot | Steal wider |
| Aggressive re-stealer | Steal tighter; add hands you can call a re-shove with |
| Short stack (10–20bb) | They re-shove often — avoid opening hands you must fold to a shove |
| Big stack who calls a lot | Steal a bit tighter; value-open more hands that play well |
| Medium stack near the bubble | Steal wider — they’re afraid to get involved |
A standard button steal
Tournament · 40bb · big blind ante
Preflop
Pot 2.5bb
- Folds to Hero on the button
- SB has 35bb and plays tight, BB has 45bb and defends a normal amount
- Hero opens to 2.1bb
- SB folds, BB folds
Keep stealing from getting too predictable
If you open every button, observant blinds will start re-stealing. Watch for:
- the same player 3-betting you repeatedly;
- short stacks shoving over your opens.
When that happens, tighten your steal range slightly and call or 4-bet shove more often against them. You’ll learn how in Reshoving.
