Why Multiway Pots Demand a Solver
When three or more players contest a pot, every additional opponent expands the range you must account for, and the number of possible interactions grows exponentially. Traditional hand-reading techniques often fall short in this environment. GTO Wizard’s multiway solver turns that maze into a clear map, showing the exact mix of bets, raises and folds that keeps your range balanced against every opponent. This guide covers how to set up the solver, read its output and apply the insights to real-time play, using a recent high-stakes hand as a concrete example.
- •One opponent range to model
- •Interactions stay manageable
- •Classic hand-reading holds up
- •Each opponent's range expands
- •Interactions grow exponentially
- •Solver map needed for balance
If solvers are new to you, start with our primer on how PioSOLVER and GTO Wizard work before diving into multiway specifics.
Setting Up a Multiway Hand in GTO Wizard
- Choose the correct table size. GTO Wizard requires the number of players in the hand. For a three-way pot, select “3-player” from the drop-down menu so the solver calculates ranges that account for two opponents simultaneously.
- Enter the stack sizes. Deep stacks are the sweet spot for GTO analysis. In the example hand the blinds were 2,000/4,000 and the stacks were 339k, 328k and 563k. Input these values exactly; the solver uses them to determine optimal bet sizing.
- Define the preflop ranges. GTO Wizard offers preset ranges for each position. For UTG+1 the solver opens with all suited A-x combos and a mix of other premium hands, and the CO’s call/3-bet range for 10-10 is also pre-loaded. If you prefer a custom range, you can manually toggle each hand.
- Load the board and hand history. Enter the flop, turn and river cards in the order they appear. In the sample hand the board ran A♠ J♥ 10♠ 5♥ J♠. GTO Wizard automatically generates the post-flop ranges for each player based on the actions taken.
- Run the solver. Click the “Solve” button. The program computes the equilibrium strategy for every street, displaying the recommended bet sizes, frequencies and expected values (EV) for each hand in your range.
Reading the Solver’s Output
The output is organised by street and hand, with a colour-coded bar showing each hand’s probability of betting, raising or folding. On the flop, for example, the solver recommends a 20% continuation bet for AKs, while pocket tens (TT) should raise at a high frequency because the board connects well with the CO’s flatting range. The key metric is EV: a positive number marks a profitable action, a negative number a mistake.
In the sample hand, the solver flagged Maue’s river call with AKs as a misstep. The EV of calling against a 37% bet was negative, whereas folding would have yielded a positive EV — which explains why the hand ended poorly for the preflop raiser. For the full breakdown of this hand, see our analysis of the AKs multiway blow-up.

Applying Solver Insights to Live Play
- Use the recommended bet sizing. GTO Wizard often suggests geometric bet sizes — consistent percentages of the pot that keep the pot size balanced across streets. In the example, a 25% block bet on the river was optimal for AKs, but the player chose a 37% bet, which tipped the balance.
- Adjust for opponent tendencies. The solver provides the equilibrium strategy, but real opponents may deviate. If you notice a player folding too often to a 20% continuation bet, you can increase your bet frequency slightly to exploit that weakness.
- Balance your range. The solver’s mix of hands that bet, raise or fold is designed to keep opponents guessing. In the hand, the CO’s 10-10 called on the flop but raised on the turn and river — a mix that forces the preflop raiser to consider whether to call or fold on later streets.
- Practice with the “what-if” feature. Change a single action — say, replace a 20% bet with a 30% bet — and re-solve. Observing how the EV shifts is the fastest way to internalise the impact of sizing decisions.
Street-by-Street Takeaways
| Street | Equilibrium recommendation |
|---|---|
| Preflop | All suited A-x combos are standard opens from UTG+1 in deep-stack multiway scenarios; defending the big blind with a wide range of suited hands remains profitable when stacks are large. |
| Flop A♠ J♥ 10♠ | A 20% continuation bet is the equilibrium size for the preflop raiser; the CO can adopt an aggressive raising strategy in position, especially when the board connects with their flatting range. |
| Turn 5♥ | The preflop raiser should use a polarised betting strategy, mixing small and large bets while checking the middle of the range. |
| River J♠ | AKs should value bet with a 25% block bet but fold to a large raise; 10-10 is a pure raise, even against a 37% bet, with a 20-bb raise recommended for maximum EV. |
Note the turn line in particular: a polarised structure that mixes small and large bets while checking the middle of the range. If that concept is unfamiliar, our guide to polarised vs merged bet sizing explains when each structure applies.
Summary
GTO Wizard’s multiway solver replaces guesswork with a concrete benchmark: load the table size, stacks, ranges and board, then compare your real decisions against the equilibrium EV for every street. The sample hand shows how much a single sizing choice matters — a 25% block bet kept AKs balanced on the river, while the 37% bet that was actually chosen turned a profitable spot into a costly one. Run your own multiway hands through the solver regularly, drill the what-if scenarios, and the theory will turn into a measurable edge at the tables.
