Don't fold second pair to a small raise when the SPR is shallow and you have significant equity against a wide range.

Flop Analysis

While checking is fine, this Ace-high board heavily favors our range as the preflop aggressor, making it a prime candidate for a high-frequency small c-bet.

Turn Analysis

After the flop goes check-check, we improve to second pair and should lean toward checking to bluff-catch, though a small bet is a viable mix. **Ranges:** BB's flop check caps them significantly, as they would likely bet most Ax or strong draws. By betting, we target their remaining high-card hands and 7x, but we risk getting raised off our equity. **Board:** The 8s is a great card for us, but it also introduces a spade flush draw. This makes the board more dynamic and increases the incentive for BB to semi-bluff raise. --- > **Takeaway:** When you improve to a marginal made hand after a flop check-back, checking is often the highest EV play to keep the pot small and realize equity.

Turn Analysis

Folding here is a significant error; we have over 50% equity against the range that raises this small, and we are getting excellent pot odds to continue. **Math:** We need roughly 31% equity to call, and our second pair is well above that threshold. The raise is small (only 4.8BB more), making a fold mathematically impossible against a range that includes spade draws and straight draws. **Plan:** Since the SPR is so low (1.17), we should actually prefer shoving over calling. Shoving maximizes our fold equity against their draws and ensures we realize our equity fully rather than folding to a river brick. --- > **Takeaway:** In low SPR situations, do not fold second pair to a non-committing raise when you still have a clear equity advantage over the opponent's semi-bluffs.

Note: Folding second pair here is too tight; with 50% equity and great pot odds, you must at least call, though shoving is the superior high-frequency play.
