This is a discussion on Monster Hands within the online poker forums, in the Learning Poker section; How would monster hands play after the flop in position early and speaking first? having top pair, do they check calls or go out directly
If it's that much of a monster hand you could just raise for value or just check to encourage a bluff or something. I usually prefer being agressive in that position since i got burned too many times playing to passive and giving them the chance to make a monster hand as well.
Once I had aces and kept checking since I knew he wouldn't pay but the river was a J and he got trips.
So agression is the answer in my opinion.
In general, top pair is not considered a monster and we’ll want to get some value but not push the action to the same extent as, say, flopping top set on a draw-heavy board
I agree. Top pair is not a monster for me, I wouldn't even call top 2 pair a monster. A set, on the other hand, is a strong hand, because set over set does occur but is quite rare. With top pair I would definitely bet on the flop, possibly also on the turn (depending if A, K or a lower top pair and the kicker), but check-call more often on the river. With a monster (made hand like straight, nut flush, full house) definitely bet for value.
