In a 4-bet pot, use small sizing to keep Villain's range wide and avoid over-committing on turns that improve their calling range.
Flop Analysis
A small c-bet is preferred on this low, disconnected texture to extract value from JJ-77 and A-high floats.
**Ranges:** We have a massive range advantage as the 4-bettor, holding all the overpairs (AA-QQ) while Villain's range is capped after calling the 4-bet.
**Sizing:** Small sizing (25-33% pot) works best in 4-bet pots with low SPR; it forces Villain to continue with hands like A5s or 77 that would fold to a shove.
**Board:** This rainbow texture is very safe for our Queens, as only a rare 53s or a set of 66/44/22 currently beats us.

> **Takeaway:** In 4-bet pots with low SPR, use small c-bet sizes to keep the opponent's range wide and maximize value from marginal hands.
Turn Analysis
While we still have an overpair, shoving for over 0.5 SPR is slightly overplaying the hand compared to a small bet or check.
**Math:** By shoving, we allow Villain to play perfectly, folding out their air and only calling with hands that have us crushed (sets, 53s) or have significant equity (AJ, flush draws).
**Plan:** Checking back or betting small (25% pot) allows us to realize our equity and potentially induce bluffs on the river from missed draws.
**Ranges:** The Jack is a better card for Villain's calling range (AJs, KJs) than ours, making this a street where we should lean toward more pot control.

> **Takeaway:** When the SPR is low but not yet zero, avoid 'clicking it in' with marginal overpairs; keeping a small sizing preserves the ability to get called by worse.
Note: Shoving the turn is too polarized; a smaller sizing or checking back preserves more EV by keeping Villain's weaker pairs and draws in the pot.
