While we turned a flush, the river pairing the board and completing a four-flush makes our small flush a pure bluff-catcher that cannot raise for value.

Turn Analysis

We turn a flush and should almost always bet to build the pot while we likely have the best hand. **Ranges:** Our range has a significant number of flushes like QsJs or 9s7s, and we need to charge SB's one-pair hands and nut flush draws like As9x. SB's range is condensed toward top pairs and middle pocket pairs that will often call a medium-to-large sizing. **Sizing:** A large sizing (80% pot) is ideal here to maximize value before the board potentially pairs or a fourth spade arrives, which would kill our action or demote our hand strength. --- > **Takeaway:** When you turn a non-nut flush in position, bet large to get value from draws and top pairs before the board texture shifts.

Note: Checking back the turn misses a massive value opportunity with a flush; we need to build the pot and charge weaker draws.

River Analysis

Raising is a significant error; the 8s is a disastrous card that pairs the board and puts four spades out, turning our hand into a weak bluff-catcher. **Board:** The board pairing and the fourth spade arriving means we now lose to any full house (8x, TT, 33) and any single spade higher than a 7. Our 7s is effectively the bottom of our flush range now. **Math:** Facing a 125% pot overbet, we are getting a poor price. SB is polarized to boats and nut flushes (AsXx) or total air; since we block some of the lower spade bluffs, calling is marginal and raising is lighting money on fire. **Ranges:** SB's overbet range is extremely strong, containing all the nut flushes we checked back on the turn. By raising, we only get called by hands that have us crushed, like a full house or the Ace-high flush. --- > **Takeaway:** On four-flush, paired boards, low flushes lose almost all value; never raise them against large bets.

Note: Raising here is a massive mistake; we are only called by better flushes and full houses while folding out all bluffs.
