Flop Analysis
On Jd 9d 5d we’ve got AKo with no diamond, so we’re just two overcards with a strong draw. UTG’s range is in good shape here, and with SPR ~3.6 in a big 3-bet pot, checking and letting UTG c-bet is the best way to realize our equity. Betting would mostly get action from stronger made hands and strong draws, while checking keeps our range protected and lets UTG fire with bluffs and weaker value.
