Flop Analysis
Once we call the shove preflop, all postflop actions are forced with SPR = 0 — the flop runout giving us an underpair plus a flush draw doesn’t matter for decision-making, since stacks are already in.
Opening 99 is great, but calling off 26BB versus a button shove after we iso a limper is a big overplay — this hand wants to fold, not gamble.

Same story on the turn — checking down with third pair and a flush draw is automatic because the hand was all-in pre; any discomfort we feel on this card is purely emotional, not strategic.
River play is also completely determined by the preflop all-in — the fact that flushes and better made hands are possible just affects the result, not our decisions, which were locked in before the flop.
