Rather then generalizing spots, try thinking deeper into the game. Why would a bluff raise be profitable in spot XYZ, why would it not? I know he only has top pair, but is he even capable of folding top pair? What am I even repping by raising? Will my opponent even be able to deduce that? Is my opponent the type to make hero calls? Are they weak tight and will fold to too much pressure?
Once you are able to think critically/technically like this, the answer to your question will become much clearer. You can even make preflop decisions based on other equities, such as how often you will be able to get them to fold or how much you can get them to bluff off, rather than just how much will I be paid off if I hit my hand.
Pretty much this. Which is why, for lower limits, I hate bluffing
rivers in general, cash or mtt. Opponents don't care what we have, hell they don't even know we have 2 cards most of the time. They just care about like, Oh wow I gotz AQo and they are two super cards and oh wow I flopped top pair on a board of AsTs4s and turn comes 5s and villain never haz flush so I GII here and win like 100% of the time because im the best MTT'er there ever was. And thennnnnn you're out lol.
