You check the turn, UTG barrels a second time, and the raise available to you is your entire stack. This puzzle is about why that is not a choice — and why more than 40% of the range facing this bet simply folds.

Hand history
Pre-flop
Flop
Turn
You hold J♥ T♥ — a heart flush draw plus an open-ended straight draw, with a queen or a seven making your straight. You checked the flop and called; the turn is the 2♦, a brick that pairs nothing and completes nothing. You checked again, and UTG has fired a second barrel of 8.6bb into 12.9bb. The pot is 21.5bb, it costs 8.6bb to continue, and you have 33.8bb behind.
