Avoid multi-street bluffing with zero equity on boards that favor the defender's calling range.
A half-pot c-bet is too large on this texture. We have a range advantage, but this specific board hits the BB's flatting range (7x, 8x, straight draws) very hard.
Note: Sizing is too large; on paired, middling boards, a small 25-33% pot bet is preferred to maintain range pressure without over-committing air.
Continuing to barrel here is a significant error. We have zero equity, no draws, and the Jack is a better card for the BB's calling range than our own.
Note: Double barreling with high card and no draw is over-aggressive; we should check-fold and preserve our remaining 14BB stack.
Once raised, this is a mandatory fold. We are drawing dead to almost everything in the BB's range and have no path to winning the pot.
