Preflop is too loose with A6o, but once we get there, pot-controlling the nut draw multiway then value-betting small with the nut flush on a four-flush board is a solid line.

Flop Analysis

Checking back the nut flush draw multiway on a monotone, connected board is fine — our equity is protected, and we avoid getting check-raised off it in a bloated pot.

Turn Analysis

Betting small for value after picking up the nut flush on the four-diamond turn is good — we’re massively ahead of almost everything and a small stab lets worse flushes and overpairs pay us without over-repping. **Ranges:** Limp-calling ranges are full of single-diamond hands and one-pair/no-diamond hands that hate facing big bets on a four-flush; a small sizing keeps their weaker flushes and some curious one-pair hands in. **Board:** The fourth diamond heavily polarizes real strength to hands with a diamond, and holding the ace of diamonds gives us the nut advantage while removing many of their strongest possible flushes. **Sizing:** Around one-third pot works well here: it prints thin value from worse while risking little and not shutting out the part of their range that can still continue. --- > **Takeaway:** On scary four-flush turns where we hold the nut flush, lean toward small bets to milk weaker holdings rather than polarizing and folding out everything we beat.
