4♠ 8♠ K♥

We turned two pair in a shallow SPR pot, making a stack-off inevitable despite the turn check-raise.

Flop Analysis

C-betting bottom pair is a viable mix here. We have a slight range advantage and can fold out BB's air while protecting our equity against their overcards.

Turn Analysis

While we improved to two pair, checking is the preferred strategy. We are out of position in a shallow SPR environment, and checking allows us to protect our range while inducing bluffs from BB's missed draws. **Ranges:** Our range contains many Kx and 8x hands that want to check-call; by betting, we isolate ourselves against BB's strongest holdings like sets or K8. **Sizing:** The 6BB bet represents roughly 50% of the pot, which is a polarizing size that forces BB to continue only with strong pairs or draws. **Plan:** By checking, we can comfortably check-call or check-shove to realize our equity without bloating the pot when we are potentially beat by a better two pair. --- > **Takeaway:** When you improve to a strong but non-nutted hand OOP at shallow stacks, checking often protects your range better than betting.

Note: Betting is a mistake here; checking is significantly higher EV to protect our range and induce bluffs on a board where BB has many draws.

Turn Analysis

Once we bet and face a raise, we are priced in to call or shove. With two pair and excellent pot odds, we cannot fold. **Math:** We are getting over 5:1 on a call, requiring only ~16.5% equity. Our two pair has roughly 77% equity against BB's continuing range. **Ranges:** BB's raise can include Kx, flush draws like AsXs, or open-ended straight draws like 65s. We beat all of these and only lose to rare sets or K8/K4. --- > **Takeaway:** In shallow SPR situations, once you hit two pair, you are committed to the pot regardless of the action.
