This flop is dynamic which means its rather unlikely that the winning hand has been made yet also another thing i’d like to point out is that many players would play a hand like AA the same on a two gap board (like in OP) the same way they would on a zero gap flop of 7s8s9s or 8h9dTc, this is wrong! since the value of AA actually goes up on a 2 gap board rather then a zero gap flop. On this board its very unlikely someone has a very strong hand. T7 would be the nuts for the straight and its not that often you’ll make a strong hand in poker plus not many would call with T7s pre, especially an offsuit one.

When I recommend checking flops because they are dynamic, it certainly doesn’t mean you are just check-folding a ton. You are checking for two reasons. First, when you c-bet a lot you are vulnerable to getting raised and getting stacks into play on boards that are likely to change significantly on the turn and river. This has the potential to get you into too many sick spots. So you are keeping the average pot smaller in unfavorable situations.

Second, you check more hands so that your check-fold frequency can go down—in other words, you are checking a higher percentage of the hands that are worth continuing or bluffing with. So, after you start with a check, you should defend a lot of hands against an opponent’s flop bet.

as for the river i’d go for a value bet , the action on the turn indicates that both players ranges are marginal. If any of those opponents had a monster hand on the turn they surely would have bet to build a pot and to get value from maybe some FDs and straight draw like JT.
