You should just check back the flop because he hit this flop way too often, and if he checks back c-bet the turn. It's often good to save your c-bet to the turn but anyway your c-bet on the flop is fine too but if he calls you down he most likely has something because it's such a dry flop so you can just fold to his bet on the turn. If you want him to fold J or 7 which he most likely has here bet big on the river like 400 but I don't see any point in that though. Just c-bet/check the flop and check/c-bet the turn. And especially because this is your tenth hand or something I'd give him a lot of credit in here. Anyway I don't like that 2x bet on preflop either because usually too much trash just floats it. Make it 2.5x or 3x. And you are not really repping here anything on the turn really except the nuts like trips etc because J would most likely just call that turn unless he has a good reads on opponent. I don't consider A too often as a scarecard in here, except maybe early on the game, but I still wouldn't 3-bet with my J here because only better call us and worse fold so what's the point? And if he checks back the river I'd probably bet but your line in here is pretty much monsters/air so yeah. People don't really tend to play back on these levels on dry boards especially early on the game on small pots(I consider 80$ pot here small cause well it is kind of irrelevant and most of the players just give up on these too easily but if they call they have something 80% of the time) so he most likely has something here.
