Work out the SPR, how much a hand is worth investing, and how many streets it takes to stack off.
Hands worth stacking off with: Overpair, top pair top kicker or better
Strong one-pair hands and big draws play for stacks; marginal pairs get cautious.
Betting 66% of the pot and getting called:
3 streets neededStacks can go in by the river.
| Bet (pot) | Streets |
|---|---|
| 33% | 5 * |
| 50% | 4 * |
| 66% | 3 |
| 75% | 3 |
| 100% | 3 |
| 150% | 2 |
* More than three streets: this size cannot get stacks in by the river without a raise or a bigger bet.
To bet the same fraction every street and be all in exactly on the last one, bet this share of the pot each street:
Equity to call off = remaining ÷ (pot + 2 × remaining), assuming the opponent bets all of your remaining stack.
Preflop 3-bet and called: pot 20.5, effective stack 90, so SPR is about 4.4, in the Medium band: overpairs and top pair top kicker can stack off, marginal pairs get cautious. Betting 66% of the pot and getting called takes 3 streets to get all in, exactly flop, turn and river; betting equal fractions to be all in on the river takes about 57% of the pot each street.
