How to read a mixed strategy
GTO outputs often say "bet 60 percent, check 40 percent". This is what that means, why solvers mix, and how to pick a clean action for a specific hand without losing the lesson.
When you look up a flop spot and the solver says bet 60 percent, check 40 percent, the very natural question is: which one am I supposed to do? The honest answer is "either, sometimes both", and the more useful answer is that the mix is telling you something about the spot, not handing you an instruction.
The percentages are about your range, not your hand
A mixed strategy describes what the whole hero range does across many trials of the same situation. "Bet 60, check 40" means that out of all the hands you can have on this flop, 60 percent of them bet here and 40 percent check. It is a statement about the population of hands, not a coin flip on every individual hand.
Some hands inside that range bet 100 percent of the time, some check 100 percent of the time, and a few sit in the middle and genuinely mix. The frequency at the range level is the sum of all those individual decisions.
Why solvers ever mix at all
If poker were deterministic, every hand would have a single best action. Solvers mix for two real reasons:
- Two actions have nearly the same EV. When a hand earns 1.42 big blinds checking and 1.41 betting, the solver is indifferent. Choosing either is fine, and many solvers express that as a 50/50 mix.
- Mixing is required at equilibrium. Some hands have to bet sometimes and check sometimes so that your check range and bet range both stay protected. If middling top pair always checked, your check range would be too strong and your bet range too thin, and a perfect opponent would exploit both.
The first kind of mix is cosmetic. The second kind is structural. Most of the time, you do not need to tell them apart: just play the higher-frequency action with most of your range and you keep almost all of the EV. The frequencies on this site come from an open-source DCFR solver, which produces both kinds of mix because the underlying counterfactual-regret-minimization algorithm cannot tell them apart either; the differences only show up when you look at the EV gap between the actions.
Picking an action for one specific hand
You hold a real two-card combination, not a range. To turn a mixed frequency into a clean decision, look at three things in this order:
- What does the hand do for itself? Strong hands that want value and protection should bet at the higher-frequency end of any mix. Weak hands that want to realise equity or bluff catch should check.
- What does the hand do for your range? A bluff candidate with backdoor equity belongs in the bet range. A medium-strength hand that blocks villain's value combos belongs in the check range as a bluff catcher.
- What about blockers and unblockers? Hands that block your opponent's value are better bluffs; hands that block their bluffs are better calls. This is the single most useful tiebreaker for close mixes.
If you still cannot tell, the spot is genuinely close and your choice barely matters. Pick the higher-frequency action and move on.
When mixing matters less than you think
Casual players read "30 percent bet" and freeze. Strong players read "30 percent bet" and ask why. The frequency itself is rarely the lesson. The reason is. If the answer to "why 30 percent" is "the board favours the caller and only the nutty part of my range wants to build a pot", you have learned a principle you can carry to every similar flop you face.
Chase the why behind every mixed frequency. The number changes by spot. The reason it mixes does not.
In live play, you are not going to roll a die at the table. A clean rule of thumb works better than an inaccurate mix. Pick the action your hand most naturally wants, weighted by the solver's bias on that street, and trust that you keep almost all of the EV by being consistent rather than randomising poorly.
Bottom line
A mixed strategy describes how your whole range splits across actions on a given board, not how to play any one hand. Some hands inside that range play pure; the mix is the sum across all of them. When you read a frequency, use it as a hint about which actions your specific hand belongs in, lean on blockers to break ties, and chase the reason the spot mixes at all. The reason is what makes you better at the next spot.
Frequently asked questions
- Should I randomise my action at the table to match the solver frequency?
- No. A clean rule of thumb works better in practice than an inaccurate dice roll. Pick the higher-frequency action consistently for that hand class and you keep almost all of the value.
- What are blockers?
- Cards in your hand that prevent the opponent from holding specific combinations. Holding the ace of spades on a three-spade board blocks their nut flush, which makes the hand a better bluff and a worse call.
- Are 50/50 mixes important?
- Usually not. A 50/50 mix means the EV of both actions is nearly identical, so either choice keeps almost all of the value. The structurally meaningful mixes are the asymmetric ones (70/30 or wider) tied to specific hand classes.
- Why does the same hand sometimes bet and sometimes check in the solver output?
- At equilibrium, your check range and your bet range both have to stay protected. Letting medium-strength hands bet some of the time keeps your check range from becoming too strong and your bet range from becoming too thin.
