Iso, call the 3‑bet, bet flop, check turn, and just check river—don’t block‑bet into a range full of straights.
Flop Ks 9c 2h rainbow, no flush possible. We’ve got top pair with a strong kicker on a dry board where our range is way ahead. Betting for value and protection is good, but the 6bb stab is too small—something around one‑third pot (≈11.5bb) applies more pressure to 9x, 2x, and random floats.
Note: Flop c‑bet is too small; a ~33% pot bet is preferred to pressure CO’s weaker hands and draws.
Turn Td connects CO’s range more than ours and SPR is ~1.6, so checking back top pair and letting CO continue with bluffs and medium strength is the disciplined line. We still have a strong hand, but we don’t need to build a huge pot on a card that helps CO’s 3‑bet range.
River Jc completes the broadway and CO’s range is now full of straights (KQ, QT, 98) plus strong Kx and sets. With SPR ~1.6 and our hand now just top pair, checking and giving up is best. The 1bb block bet is a big mistake—CO will rarely fold a straight and will often raise, so we’re just lighting money on fire.
Note: River block bet is a big mistake; with SPR ~1.6 and CO’s range full of straights, we should just check and give up.
