The hand

A 3-max spin-and-go, 10bb stacks, no antes. The Button folds and the action is on you in the Small Blind with K♦ 6♣, heads-up against the Big Blind. There is 1.5bb in the pot from the blinds, your 0.5bb and the Big Blind's 1bb. At this depth there is no room for a small raise and a fold later; the choice is all-in or nothing. A king-high hand with a weak kicker, one opponent left, and a short stack. Shove or fold?

How to think about it

Answer first: the walkthrough opens as soon as you choose, with the numbers behind the right play.

Best answer: All-in for 9.5bb

Two ways to win
Move all-in and you win two ways: everyone folds and you take the blinds, or someone calls and you win 39% of those showdowns.
What it's worth
Folding is worth nothing. Moving all-in is worth +0.37bb on average.
The decision
The shove earns more than folding, so moving all-in is right.

The full reasoning

Shoving is right. Two things pay for the jam. First, the folds: the assumed calling range is 22+, A2s+, A2o+, K4s+, K8o+, Q8s+, QTo+, J8s+, J9o+, T8s+, 98s, 87s and 76s, the Big Blind's call against a 10bb shove from the embedded push/fold table, and most hands are not in it, so most of the time you simply pick up the 1.5bb in the blinds. Second, the showdowns: when the Big Blind does call, K♦ 6♣ still wins ~39% of the time, because the calling range includes queen-high, jack-high and ten-high hands your king is ahead of. Put together, the shove is worth about +0.37bb more than folding: small but real. Folding is graded as close rather than an error, since the gap is under half a big blind, but it is still the wrong side of zero every time you do it. Heads-up at ten blinds, a king-high hand shoves: the folds you collect are worth more than the showdowns you lose. That is the concept, and it is why push/fold tables are so wide from the Small Blind at this depth.
