This is a discussion on Typical BB defend within the online poker forums, in the Learning Poker section; Unknown opponent make a standard op-raise and c-bet50%.
You defend BB with a call and now have 2nd pair.
Flops are typical:
K♦ 9♣ 5♠
J♥ T♠ 7♠
Depends on the range the RFI is playing, which against a thinking player mostly depend on position. Against a UTG open on an ace-high board, you should probably fold. Against a BU open you could get sticky. Check-raising with a marginal holding is bad most of the time, you really just want to realise your equity share.
What makes poker fun (and profitable) is that there are no hard rules for general situations like this. It always depends on a lot of different factors. If it were easy, everyone would do it.
If I flop second pair on boards like those, I will almost always check-call a 50% pot bet. Second pair definitely has showdown value against a flop C-betting range, and it also has potential to improve to trips or two pair. If we fold, we are folding way to much to C-bets, and second pair is typically not strong enough to check-raise.
Its quite common to then end up folding to a second or third barrel. But thats ok, because it puts the opponent to the test to actually fire those barrel and in tournaments maybe risk a large percentage of their stack. If the opponent has nothing, its quite common, that they will give up and check behind, and then we can get to showdown and be good with our second pair. Or if they check back turn, we can either bet or check-call river on some runouts.
Configuration and exact board texture also matter though. If the opponent opened UTG, I am more excited about having QT on JT7 than on AQ4, because I expect the opponent to have way more AX than JX in his range, and on JT7 I also have some backdoor straight potential.
Probably depends on player types and my own table image. If a completely unknown opponent (like we have here), then I'm more likely to play straight-forward or fold the first few hands to observe how they play.
Ironically, if playing live poker, then no one is completely "unknown" because I can observe how present themselves and interact with others even before the poker game begins.
I don't like the check-raise ideas mentioned. It might work for some people, but I feel like check-raising is only getting called by hands better than 2nd pair.

Its really hard to say to be honest. I would depend on who is raising me and what style player they are and what they have in there range. I could lead or or check call and could check raise. Its really player dependent to me.
Against a weak/medium opponent, I prefer to follow the check/raise line on the flop, but knowing that I need to have enough chips to release another strong bet on the turn and river if need be, many bad players don't release a draw or a pair. average so easily. Against a good player, I prefer to re-steal preflop, to fold to a 3bet, but I only do this with a hand that I can play postflop, many good players will call re-steal to steal the pot in any sign of weakness.
