While 3-betting 65s is a great squeeze, we overplayed the hand postflop by using large sizings on a board that favors the caller's condensed range.
Flop Analysis
While we have a massive combo draw, the 75% pot sizing is an overplay. In a 3-bet pot with a low SPR (~1.9), we should lean toward checking or using a small sizing (33% pot) to keep the range wide and realize our equity cheaply.
**Ranges:** The SB's calling range is condensed with hands like 77-JJ and suited broadways. While we have the nut advantage (AA, KK, AK), the SB has many Kx combos that are never folding to a single large bet, making our fold equity lower than it appears.
**Sizing:** A small 33% pot bet achieves the same goal of denying equity to overcards while keeping the pot manageable. Blasting for 75% pot bloats the pot and forces us into a 'shove-or-fold' mentality on the turn if we don't improve.

> **Takeaway:** In low SPR pots with strong draws, use smaller sizings to maintain flexibility and realize your equity without over-committing against a sticky range.
Note: The 75% pot sizing is too large; a check or a 33% pot bet is preferred to maintain range balance and realize equity.
Turn Analysis
Shoving here is a significant mistake. Improving to middle pair actually makes our hand a better check-call than a shove, as we now have showdown value and can still hit our monster draws on the river.
**Board:** The 6h is a 'dynamic brick.' It gives us a pair, but it also completes the 45 straight (though we hold those blockers). It doesn't change the fact that the SB's range is still heavily weighted toward Kx hands that aren't folding.
**Math:** By shoving, we turn a hand with 55% equity into a bluff. We only get called by better hands (Kx, sets, 77) and fold out the air we already beat. Checking allows us to realize our equity for free or catch bluffs from missed draws.
**Plan:** Checking protects our entire range. If we shove all our draws and pairs, our checking range becomes extremely weak and exploitable. Middle pair + flush draw is the perfect candidate to check-call and evaluate on the river.

> **Takeaway:** When you improve to a marginal pair with a draw, check to realize equity and bluff-catch rather than turning your hand into a low-fold-equity shove.
Note: Shoving middle pair + draw is an overplay; checking allows you to realize equity and protect your range.
