The Player With No Position Bets First — 67.4% of the Time

Across the seven single-raised pots earlier in this series one rule kept repeating. Whoever acts first checks. The highest the out-of-position player ever bet was on the 9-8-7 connected board at 23.7%, and the other six topped out at 11.2%. The only exception was a three-bet pot.

This is not a three-bet pot. It is an ordinary hand: the small blind opens to 3bb, the big blind calls. And the player who acts first bets 67.4%.

What changed? The pot is small at 6bb and the stacks are 97bb deep. What changed is who acts first, and which range the board favors — both at once. Every number below comes from the HoldemMaster GTO solver.

Quick answer

On K-T-6 blind vs blind the small blind's first action is bet 67.4%, check 32.6%. That is the reverse of the 0.1%–23.7% seen in spots ① through ⑦, and two things are different, not one: the out-of-position player here is the raiser rather than the caller, and the board is a king with a broadway kicker. The seat alone does not explain it — the same small-blind raiser bets only 9.6% on a 7-6-5 board later in this series. Here the two line up, so the preflop aggressor is also first to act and holds the range edge and the action order together. The result is an out-of-position equity realization of 103.1% — the first time in a single-raised pot that it clears 100%.

What conditions produced these numbers?

★The setup has changed again. Pot, stack and roles are all different from the earlier spots, so the table comes first.

The 6bb pot is the SB's 3 plus the BB's 3. Both blinds are already in the hand, so there is no dead blind on the side. The effective stack is 100 − 3 = 97bb.

The display is in big blinds — bets read as "Bet 2bb (33% pot)", with the amount and the pot fraction together, and EV reads as "EV (bb)".

How often does the small blind actually bet?

67.4% bet, 32.6% check. Of 538 combos, 362.1 go into the bet.

Lined up against the rest of the series, the gap is obvious.

Do not read this as "the seat is all that matters." The same small-blind-opener seat produces 9.6% at ⑫, 67.4% here and 80.1% at ⑬ — a spread of 70.5 points. And ⑫'s 9.6% is lower than the callers at ⑤ (11.2%) and ④ (23.7%). The picture of a cliff between callers and aggressors only appears if you delete those two rows. What is certain is that the three-bet pots (98–100%) sit apart; the rest of the spread is set by the seat and the board together.

Why does the out-of-position player lead here?

Because this is the seat where the preflop aggressor also acts first on the flop. ⚠ That is a necessary condition, not a sufficient one — the same structure produces 9.6% at ⑫ and 80.1% at ⑬. The seat opens the door; the board decides how far you walk through it.

In an ordinary hand these two come apart. When the button opens and the big blind calls, the aggressor is the button but the first to act is the big blind. That is what builds the check-then-c-bet structure, and it is what ① through ⑦ all looked like.

Blind versus blind, the two collapse into one. The small blind raised, and the small blind is first on the flop. The range edge and the action order land on the same player.

⚠ Do not delete the third row. "Together" opens the door without deciding how far you go — ⑫ has a seat structure identical to this one, letter for letter, and bets 9.6%. Without the overlap you rarely lead at all (the first row); with it, you still need the board to fit your range before you actually bet.

Equity puts a number on that edge. SB 55.3% against BB 44.7%. In ① through ⑦ the out-of-position player sat at 45.1%–48.5%, always short of half — the opposite direction.

“

A check is not something you do because you lack position. It is something you do because your range is weak on this board.

Lacking position is the same for the big blind in ①–⑦ and the small blind here. What splits them is the relationship between range and board — ⚠ and you cannot reduce that to "range" alone. On the 7-6-5 board the range is literally identical and the check runs to 90.4%.

Why 67% here when a three-bet pot is 100%?

Because the big blind's defending range is wide. That is where this spot parts from the 100% bet in a three-bet pot.

The two ranges here are almost the same size: 538 combos for the SB, 525 for the BB. That many hands came along instead of folding. The small blind only raised to 3bb, so the big blind — already in for 1bb — had to add just 2bb, and the price was good enough to defend wide.

Against a wide range you cannot bet everything on the chance they fold. So 32.6% stays back as a check.

The checking hands have jobs of their own. Hands too weak to bet and hands that check to induce a bet both live there. If the opponent reads that check as weakness and fires, a check-raise is waiting.

How do the two ranges differ?

The strong classes sit with the small blind; the unmade hands sit with the big blind.

Two cells decide it. Top pair runs 15.6% to 10.9% in the small blind's favor, and unmade hands run 24.5% to 34.3% — nearly 10 points more for the big blind.

⚠ Do not read "unmade" as "has nothing," though. The solver counts draws on a separate axis — the four rows below are mutually exclusive and each column sums to 100%.

There is no flush-draw row at all — the board is a rainbow, so neither player can hold four to a flush on this flop. What they have instead is a thick backdoor slice, and a backdoor needs runner-runner, so it completes rarely.

The 3.0% open-ender works out to 0.030 × 538 = about 16 combos, and on this board exactly one hand makes an open-ender: Q-J (K-Q-J-T, needing an ace or a nine — eight outs). Sixteen is precisely the number of Q-J combos. The gutshot row is thicker because A-Q, A-J, Q-9, J-9, 9-8 and 8-7 all land in it.

Still, when a third of the opponent's range has not even paired and your own top end is heavier, betting small and wide is the standard.

Sets point the same way. Three pocket pairs make a set on this board — K-K, T-T and 6-6 — and the small blind holds all three, nine combos (1.7%), while the big blind is left with 6-6 alone, three combos (0.6%). The big blind three-bets K-K and T-T against a small-blind open rather than calling. Overpairs belong to the small blind for the same reason: A-A, six combos.

Why is equity realization 103.1% without position?

Because the range edge barely outweighs the positional one. Put this spot's numbers on the whole series and the answer shows.

The pot is 6bb, so the small blind's share is 6 × 55.3% = 3.32bb while the actual EV is 3.42bb. That is 3.42 ÷ 3.32 ≈ 103.1%.

Pick seven spots from the series and rank them by EQR:

Every row above 100% belongs to someone who is not the caller. ⚠ Do not read it backwards — "not the caller" does not imply "above 100%." The 7-6-5 board, missing from this table, is the same small-blind opener at 85.3%, sitting among the callers. And this spot is the closest to the line of any of them: 103.1% clears it barely.

⚠ Nor does a higher EQR mean a bigger edge. Read the ranking as it stands — the biggest range edge in the table, ⑧ at 68.9% equity, lands on 109.6%, below ⑨'s 117.8% at 58.3% equity — ten points less. EQR is EV ÷ (equity × pot), so equity is the denominator: the lower it is, the larger the ratio for the same EV. It is true that one open-raise of edge stops at 103.1%; the reason is not "it could have reached 117.8%."

The big blind's 96.1% is the other face of the same story. Position, and still short of its share. Why position usually pays, and when it is not enough, is in why position matters.

What changes at the table?

• •Blind versus blind, do not default to "no position, so check." If you opened from the small blind, the preflop range edge is yours, and the solver bets 67.4% on this board. But you still read the board — a king with a broadway kicker suits the opener, and on boards that fit the caller the check comes back even from this seat. The 7♦6♦5♣ connected board is exactly that: the same small blind bets only 9.6%.
• •The size is a third of the pot. With the big blind defending 525 combos, small and wide is right. ⚠ Do not turn that into "betting big is worse" — this study spot only had the 33% size in the tree. With no larger size solved, "what if I had bet big" is a question this calculation cannot answer. The A-A-6 spot later in the series does have 75% open alongside it.
• •★At SPR 16.2, decide in advance what a raise means. Betting 67.4% of your range means facing raises often, and with sixteen pots left behind you this is not a stack-off spot for top pair. That is the reverse of a three-bet pot at SPR 4.0, where "raise" meant "the stack is going in." Here calling and seeing a turn covers far more of your range, and outside nine set combos and two pair (K-T, K-6, T-6) there is little reason to commit — 🪶 note that A-A is below two pair here (an overpair pinned under the king; the class table reads set 1.7% · two pair 2.4% · overpair 1.1%). ⚠ The node after a raise is not in this solve, so this is judgment drawn from the SPR, not a solver number.
• •Defending the big blind, remember what three-betting K-K and T-T costs you. The result is exactly the structure on this board: the big blind's only set is 6-6. The calling range thins out by that much.
• •Do not read the 32.6% of checks as weakness. Check-raising hands are mixed in. The general standards in c-bet strategy are worth double-checking in this seat.

QShould the small blind always c-bet blind versus blind?▼

Not always. On this board the solver bets 67.4% and leaves 32.6% as a check. But that is a different world from an ordinary single-raised pot, where the out-of-position player bets 0.1%–23.7%. When the role changes, the default changes. Bear in mind that K-T-6 is a board that suits the opener — just as one board type split 0.1% from 23.7% in the earlier spots, the small blind's betting frequency drops on boards that fit the caller.

QIs being out of position always bad in poker?▼

Bad, but not decisive. In this spot the small blind takes 103.1% of its equity share with no position, while the big blind, holding position, collects only 96.1%. A big enough range edge covers a positional one. Run it the other way — a weak range realizes poorly even in position.

QWhy bet as small as a third of the pot?▼

Because the opponent's defending range is wide. The two ranges are almost the same size, 538 combos to 525. Against someone you cannot expect to fold, pressuring wide with a small size earns more. Bear in mind that this study spot had only the 33% size as a candidate.

QWhy is 6-6 the big blind's only set on this board?▼

Because K-K and T-T get three-bet against a small-blind open rather than called. So the big blind's calling range keeps only 6-6, three combos (0.6%), while the small blind holds K-K, T-T and 6-6 for nine (1.7%). A-A is absent from the big blind for the same reason.
