2♠ J♠ A♥

While our top pair is strong, the four-spade runout and heavy pressure from the CO make this a disciplined river fold.

Flop Analysis

Checking is the preferred play with our entire range here. We have a slight equity advantage, but checking protects our marginal hands and allows CO to bluff their air.

Flop Analysis

Calling is mandatory. We have top pair in a 3-bet pot with decent equity against a range that includes many spade draws and weaker Jx.

Turn Analysis

The 5s is a dynamic card that completes the flush. We must check our entire range to the in-position aggressor.

Turn Analysis

This is a very close decision. While we have top pair, the flush is now possible and we don't hold a spade to block Villain's value range. **Ranges:** CO's betting range is polarized between flushes (Kxs, Qxs) and semi-bluffs. By calling, we are essentially hoping they are over-bluffing with hands like KQ or T9 with a spade. **Math:** We are getting 3:1 on a call, needing about 25% equity. Our hand is right on the threshold, making it a high-variance mix between calling and folding. --- > **Takeaway:** On flush-completing turns without a blocker, top pair with a weak kicker becomes a marginal bluff-catcher.

River Analysis

Checking is correct. With four spades on board and no spade in our hand, we cannot value bet and must check to see what Villain does.

River Analysis

Folding is the disciplined and correct play. The board is now extremely wet, and we lose to any single spade in Villain's hand. **Blockers:** We hold the Ad, which is the worst possible Ace to have here. We don't block any of the CO's spade flushes (like KsQs or QsTs) and we don't have a spade ourselves to call with. **Ranges:** CO's range is heavily weighted toward flushes and straights (QK) after betting three streets. Even if they are bluffing, they often have a spade that has us beat anyway. --- > **Takeaway:** When the board runout completes multiple draws and you hold no blockers to the nuts, let go of one-pair hands.
