Its all down to your opponent, if a passive opponent raises you on a dry board and your looking at top pair TP/GK, your probally beat,
if youve seen this guy raise this kind of board before with less than 2 pair, you got good reason to be calling down, or raising all in, maybe some fish who trying to get all in with no reads on the flop with top pair no kicker,
wet board, now its a little tricky coz theres a ton of draws that looking to raise, it all depends on the reads you have on your opponent, even if the opponent hasa draw your looking at a flop at best, if the opponent is passive,
how often are your opponents bluff raising? if hes not bluff raising what does he raise for value ?
