Heads-Up Hold’em practice rules
- One isolated no-limit hold’em hand uses equal 50 big-blind stacks. Positions alternate each hand. Your complete table stake leaves the local wallet at Deal; your remaining stack and any winnings return after the hand.
- The local opponent estimates equity with 256 fresh injected-randomness rollouts against unknown hole cards and runouts. It folds when equity trails pot odds by more than five points, otherwise checks/calls, with threshold raises at 62%, 78%, and 92% equity. It never reads your hidden cards, adapts, or stores play history.
- Raise choices are Minimum, Half Pot, Pot, and All-in. Equal stacks remove side-pot cases.

About this game
An opponent that computes its equity every decision
Heads-Up Hold’em plays no-limit Texas hold’em one-on-one against a computer opponent that estimates its actual chance of winning before every action. It is not following a script or a difficulty curve — it runs hundreds of simulated hand completions and decides from the number.
Typical session: 3–10 minutes.

Playing against a calculating opponent
Standard hold’em, one opponent
Each player receives two private cards, and five community cards are dealt across three betting rounds — the flop, the turn, and the river. The best five-card hand from your two cards plus the five shared ones wins the pot.
Betting is no-limit in structure, with raise sizes offered as half-pot, pot, and all-in. Three table stakes are available, which changes the ratio between your stack and the blinds and therefore how much room there is to manoeuvre after the flop.
The opponent does not see your cards. It works from the same public information you do — the board, the pot, the betting history — plus its own two cards.
Pot odds are the language it speaks
The opponent folds when the price of a call exceeds its estimated chance of winning by a small margin. That is a pot-odds decision, and it means bet sizing genuinely works against it: a larger bet demands a better hand to continue, and it will lay down marginal holdings to real pressure.
It raises on a threshold ladder rather than by feel. Very strong equity commits it all-in; strong equity produces a pot-sized raise; moderate equity produces a half-pot raise; below that it checks or calls. Because it only raises once per street, its second action on a street is much less informative than its first.
The exploitable consequence is that its aggression is a fairly honest signal. A large raise from it genuinely means a strong estimate, so folding marginal hands to its big bets is usually correct. Conversely it will not bluff you off a hand with nothing — if it is betting big, believing it is the right instinct.
When stacks are shallow relative to the pot it becomes much more willing to commit everything on merely decent equity, so short-stack situations turn into coin-flips more often than deep-stack ones.
How the opponent decides
Before each action it runs a large batch of simulated completions of the hand from the current board, counting how often it ends up winning. That fraction is its equity, and every decision below is made against it.
The thresholds are worth reading as a description of its personality rather than a table of numbers. It needs to be a heavy favourite before committing everything, and it will only raise once per street, which means a check from it on a later street says far less than a check on the first. Between those bands it simply calls, so a large share of its actions carry no information at all — the informative moments are the raises.
| Estimated equity | Action |
|---|---|
| 92% or above | All-in |
| 78% to 92% | Pot-sized raise |
| 62% to 78% | Half-pot raise |
| Above the price of a call | Check or call |
| Clearly below the price of a call | Fold |
Common mistakes
Most losses come from treating it as either a bluffing human or a mindless caller.
- Calling its large raises with marginal hands. It raises big on genuine equity, so those bets are honest — this is not an opponent to catch out.
- Trying to bluff it with tiny bets. It compares the price of a call against its equity, so a small bet gives it excellent odds and it will simply call.
- Betting small for value. If you have a strong hand, a larger bet is the one that maximises what it pays before folding.
- Playing short stacks the same as deep ones. With a low stack-to-pot ratio it commits everything on moderate equity, so marginal hands become far riskier.
What is different about this version
The opponent estimates its equity by simulating hundreds of completions of the current hand rather than consulting a lookup table or following a scripted line. It genuinely computes how often it would win from where it stands, which is why its behaviour changes appropriately with the board rather than with a difficulty setting.
It never sees your cards. Every decision comes from the public board, the pot size, the cost of calling, and its own two cards — the same information available to you. There is no hidden advantage compensating for a weaker strategy.
Common questions about Heads-Up Hold’em Practice
Does the computer opponent see my cards?
No. It works from the community cards, the pot, the betting history, and its own two cards — exactly the information you have. Its strength comes from calculating equity accurately, not from peeking.
Can I bluff it?
Yes, but only with meaningful bet sizes. It folds when a call costs more than its estimated chance of winning, so a large bet can push it off a marginal hand while a small one simply gives it the odds to call.
Does it bluff me?
Essentially no. Its raises are driven by genuine equity thresholds, so a big bet from it reflects a strong estimate. Believing its aggression is usually the correct read.
Why does it play differently at higher stakes?
The table stakes change your stack relative to the blinds. When that ratio is low it will commit everything on moderate equity, so short-stack hands resolve as all-ins far more often than deep-stack ones do.
