While 99 is a strong bluff-catcher, raising the flop and betting the turn turns a medium-strength hand into a vulnerable one, inviting a disaster scenario.
Raising here is a significant mistake that overplays our hand's actual value. We should call to keep HJ's bluffs in and realize our equity on a dry board.
Note: Raising with 99 on a paired board is unnecessary; it folds out the bluffs we beat and isolates us against Jacks and better.
Checking back is the only play here. The second Jack is a terrible card for our range, and our hand now functions purely as a bluff-catcher.
Note: Betting the turn after the board double-pairs is an overplay; we have zero value to gain and only risk getting check-raised off our equity.
Despite the previous errors, we are now priced in to call the shove. We only need to be right about 25% of the time to break even.
