Underpairs facing barrels on broadway-heavy boards lack equity realization and must be folded early.
Flop Analysis
Facing a 65% pot c-bet on a board with two broadway cards, our underpair lacks the equity and playability required to peel. We should fold immediately rather than float.
**Ranges:** The raiser enjoys a distinct range advantage on high-card textures, holding plentiful top pairs like AsKs and KsQs alongside strong draws, while our underpair sits at the bottom of our range.
**Plan:** Continuing here creates massive reverse implied odds, as nearly every turn card (A, Q, J, or spade) worsens our relative hand strength and forces folds to subsequent barrels.
---
> **Takeaway:** Underpairs to multiple broadway cards lack the equity realization needed to continue against standard c-bets.
Note: Calling a 65% pot c-bet with an underpair to two broadway cards is -EV; fold immediately.
Turn Analysis
Calling this second barrel is a critical error. The Ace connects heavily with the raiser's range, completing broadway straights with QJ while improving their Ax floats to top pair.
**Ranges:** The aggressor's double-barrel range is heavily concentrated in two pair holdings such as AK and sets, leaving our underpair drawing virtually dead.
**Math:** Needing over 28% equity to call, our hand has less than 23% raw equity against this range and almost zero playability across river runouts.
---
> **Takeaway:** Do not call turn barrels when scare cards fall that drastically improve the aggressor's range.
Note: Calling the turn barrel with an underpair on an Ace-King board burns significant EV; folding is pure.
