Hands with a :0.5-style suffix are mixed — the solver plays them that fraction of the time. Copy this string into the equity calculator to run it against a specific hand.
Where this came from: Cash open-raise charts from solver-core's preflop solver (engine v0.1.0). Postflop continuation values calibrated against real postflop solves (Phase B) at 100bb and reused at this depth. No cross-player card removal; cold-continues vs 3-bets pruned. See the methodology page. Converged to 0.00088 bb of Nash distance.

Static charts can't adapt to your opponents
Sharkling's neural solver does — it re-solves the spot for the table you're actually sitting at, then drills you on it.
Playing the under the gun
Under the gun you are first to act preflop and, unless everyone folds to the blinds, you will be out of position for the rest of the hand. Five players remain behind you, each with a chance to wake up with a better hand. Both facts push the same way: open tight.
The range is roughly pairs down to about 55, the strong suited aces and broadways, and the better offsuit broadways. Suited connectors below about 87s are marginal here because you will frequently be playing a bloated pot out of position with a hand that flops a draw and nothing else.
The most common UTG mistake is not opening too tight — it is opening the right hands and then continuing too far with them. A hand that is strong enough to open under the gun is not automatically strong enough to call a 3-bet.
The other seats
Position changes the correct range more than any other single factor. Compare:
- Middle position (hijack) — opens 21.5% of hands
- Cutoff — opens 29.6% of hands
- Button — opens 49.3% of hands
- Small blind — opens 40.6% of hands
Once you know which hands to open, the next question is how they perform when called. The equity calculator will run any of these ranges against a specific hand or another range — paste the range notation from above straight into it.
Frequently asked questions
What is a preflop chart?
A grid of all 169 starting hand types showing which to raise, call or fold from a given seat. It is the compressed output of a solver run: the machine plays the spot millions of times and the chart records the strategy it settles on.
Should I follow preflop charts exactly?
As a default, yes — they are far better than instinct, and preflop is where the most money is lost to bad habits. But charts assume opponents who play back correctly. Against players who never fold or never defend their blinds, deviating is where the profit is.
Why does position change the range so much?
Two reasons. Acting last after the flop is worth several big blinds per 100 hands on its own, and opening from an early seat leaves more players still to act behind you. The button opens roughly four times as many hands as under the gun.
Do these charts work for 9-handed games?
The shapes carry over but the ranges are tighter, because five more players are yet to act. These charts are generated for 6-max; treat 9-handed early position as tighter still than the UTG chart shown here.
