Leading into the preflop raiser on dynamic boards is a major leak; check-calling allows you to realize equity without bloating the pot against a stronger range.
Leading here is a significant strategic error. We should check our entire range to the preflop aggressor who holds the nut and range advantage on this high-card texture.
Note: Donking (leading) into the preflop raiser on a board that favors their range is a massive leak; checking is mandatory to protect our range.
After leading the flop, doubling down on the turn is another mistake. While we improved to top pair, the board is now incredibly coordinated, and we should be in check-call mode.
Note: Betting into a range that contains many straights (K9, 98) and two pairs (QJ, JT) is overplaying a marginal top pair.
Facing the raise, we are priced in to call. We have top pair and an open-ended straight draw to the nuts, giving us enough equity to continue despite the range disadvantage.
Checking is the only play on the river. The board paired the Jack, which is a terrible card for us as it improves Villain's Jx hands to trips and doesn't help our two pair.
