Defending pre and raising flop small is fine, but once the SB re-raises on this Ace-high board, we’re effectively committed and jamming top pair is high-variance but not a big punt.
Flop Analysis
Raising the small c‑bet with top pair/top kicker and a backdoor nut flush draw is reasonable as a protection/value raise, but calling is at least as good given SB’s range advantage on this Ace-high texture.
**Board:** SB, as preflop raiser, has all the strongest Ax and sets here, while our BB defend range has more medium-strength and draw-heavy hands; the diamond draw and some straight draws mean equities run fairly close, but SB still owns the nut region more often.
**Ranges:** Our hand is near the top of our range (strong Ax plus backdoor diamonds), but SB’s c‑betting range is very wide, including many weaker Tx, 6x, small pairs, and diamond draws; calling keeps those weaker hands in and maintains our range’s flexibility.
**Plan:** By just calling, we keep SPR healthy (~2.7 after a call), allow SB to continue bluffing with misses, and avoid polarizing our hand into a raise line that later faces big re-raises from a range that’s structurally stronger.
---
> **Takeaway:** With a strong but non-nut top pair in a spot where villain has the range advantage, default to calling small c‑bets and mix in raises selectively rather than auto-protecting.
Note: Raising the first flop bet is okay but slightly lower EV than just calling versus a range-advantaged SB.
Flop Analysis
Once SB 3‑bets the flop small and SPR drops near 1, jamming top pair/top kicker with our backdoor equity is defensible: we’re effectively committed and deny equity from SB’s strong draws, even though we’re behind the very top of their range.
**SPR:** After SB makes it 7BB, there’s already a sizable pot and only ~26.5BB behind; calling leaves an SPR <1 on the turn, meaning stacks are almost always going in on many runouts anyway.
**Ranges:** SB’s flop 3‑bet range is heavily weighted toward strong Ax (AK, AQ, sometimes AT), sets (TT, 66), and strong diamond or combo draws (KQdd, QJdd, etc). Our AJo does well versus draws and some weaker Ax but is in bad shape versus sets and two pair, so their value side is strong.
**Range Construction:** For our overall strategy, we need some strong top pairs to continue aggressively alongside nut draws; if we only jam draws, our line becomes too bluff-heavy and exploitable once called. Using AJo as part of that aggressive continuing range is reasonable at this SPR.

> **Takeaway:** After a flop raise gets 3‑bet and SPR collapses, treating strong top pair as a stack-off hand is high variance but strategically sound, especially when it also punishes villain’s draw-heavy continuations.
Note: The shove slightly overplays top pair versus a very strong 3‑betting range, but given the shallow SPR it’s at most a small EV loss, not a big blunder.
