Heads-Up for the Title
Two players left, trophy and the biggest pay jump on the line. Heads-up is its own game — wider ranges, more aggression, and one positional quirk that trips up the unprepared.
Everything just got wider
You're in the blinds EVERY hand — nowhere to hide, no folding your way to first. Buttons play 60-90% of hands. Any ace, any king, and every pair shoot up in value.
Raise or fold the button — skip the limp
You have position on 3 of 4 streets, so attack. Min-raise (2x-2.5x) or open-shove when short. Open wide: all pairs, any ace, any king, most broadways and suited stuff.
Heads-up, 9bb effective, you're the small blind (button). It's folded to you. Shove or fold?
Position wins the small pots
On every postflop street the button acts last and sees the big blind decide first. That means thin value bets, cheap bluffs, and free pot-control by checking behind. Heads-up is a game of many small pots.
Heads-up final, blinds are big. Which starting hand would you rather open-shove for 12bb?
Adjust to stack depth
Deep (40bb+) you can float (call a bet with a weak hand, planning to take the pot away on a later street), 3-bet (re-raise) and outplay. Around 15bb and below it collapses into push/re-shove where math beats reads. At 8-12bb the button open-shoves very wide.
Read the one player in front of you
Same opponent every hand, so patterns show fast. Folds too much? Raise every button. Check-calls the flop then gives up on the turn? Fire two barrels (keep betting on the flop AND the turn to push them off). Only bets when strong? Stop paying them off.
- The button posts the small blind — first to act preflop, last on every later street. Position is your edge on 3 of 4 streets.
- Ranges are huge: any ace, any king, all pairs, most suited hands. Folding your way to first is impossible.
- Raise-or-fold the button, defend the big blind wide, and lean aggressive when in doubt.
- Below ~15bb, heads-up becomes a push/re-shove game where math trumps reads.
- One opponent every hand — find their biggest leak fast and exploit it relentlessly.
Test yourself
Answer them all — 18/22 to pass. Every answer gets an explanation.
In heads-up No-Limit Hold'em, which player posts the small blind?
Heads-up, the dealer button posts the small blind; the other player posts the big blind.
Preflop heads-up, who acts first?
The button acts first preflop, then last on the flop, turn, and river.
On the flop, turn, and river heads-up, who acts last (in position)?
The button is out of position preflop but in position on all three later streets — its key advantage.
Why is folding your way to a heads-up win impossible?
With only two players you are always in a blind, so you cannot sit and wait — you must contest pots.
Roughly how much of a big blind does each orbit (both blinds) cost you heads-up?
Each orbit you post one small blind (0.5 BB) and one big blind (1 BB) = 1.5 BB total.
How wide should a competent button typically open heads-up?
Positional advantage and constant blind pressure justify a very wide button-opening range.
How do high cards like any ace or any king change in value heads-up versus a full table?
In heads-up pots top pair or even ace-high is often best, so high-card strength rises sharply.
Which is generally the biggest leak for a losing heads-up player?
Over-folding the big blind lets the button steal uncontested and is the most common and costly leak.
With a deep stack (40+ big blinds), heads-up play should emphasize:
Deep stacks reward postflop skill and multi-street play rather than all-in gambles.
Around 8-12 big blinds heads-up, the button's standard approach is often to:
At that depth open-jamming a wide range is a simple, effective push/fold strategy.
Why does the out-of-position player (big blind postflop) lean on check-raises and check-calls?
Acting first, they let the in-position player commit chips first rather than betting into someone who reacts with full information.
What is the general default for the button when facing a decision it's unsure about heads-up?
Passive heads-up play loses; when in doubt, betting and raising pressures the opponent.
Why is heads-up considered the most exploitative form of poker?
One opponent hand after hand lets you build and attack a precise model of their tendencies.
Your opponent check-calls flops but consistently gives up on the turn. You should:
A player who folds turns after calling flops is exploitable with double-barrel bluffs.
Your opponent only bets when they have a strong hand. The correct adjustment is:
Against a player who only bets value, over-folding your marginal hands is the profitable response.
Limping the button heads-up is best described as:
Raise-or-fold is the common default, but limping is a legitimate tool in specific spots and stack depths.
Compared to a full table, how does the big blind's defending range change heads-up?
Facing a wide, single-opponent button raise while getting good price, the big blind defends a large portion of hands.
Below roughly 15 big blinds heads-up, decisions are dominated by:
Short stacks turn most spots into all-in decisions governed by equity and fold-equity math.
Heads-up for a tournament title, first versus second place, the button seat is valuable primarily because:
Despite acting first preflop, the button's positional edge on the three later streets makes it the seat to win from.
Heads-up, King-four offsuit on the button should usually be:
A king dominates much of the opponent's range and you have position postflop, so it's a standard button raise.
Ace-nine offsuit in the big blind facing a button raise should usually be:
Ace-high with a solid kicker is premium heads-up; folding it donates chips to the button.
Why is variance high in a heads-up match?
With few decisive pots and wide ranges, even a skilled player loses individual matches often.
