It really depends on how many players (6max vs FR), effective stack sizes, player profiles, your table image, etc. Generally you can comfortably fold hands like 7c9c or Ts8s from early position. Those hands just don't play well, and because your out of position you can't play them NEARLY as effectively.
Conversely. I would be drooling if I could get either of those holdings fairly deep against a fish with aces, but only in position. The reason why is because when we play connectors, we are peeling (floating) 100% of boards in position, because our hand is almost always connecting somehow.
we can make
1. flush draws, 3 flushes, 3 straights, straight draws, pairs, etc. And all of those hands can increase their
equity on the turn.
Furthermore, if our opponent bets on the flop, and we just flat, that is actually interpreted as much stronger than a raise. Therefore, when the villain checks turn, we can bet and win a lot of the time.
If we get flatted on the turn, our hand probably has between 18-35% equity so we can value bet rivers against fish, or 2 barrel
bluff if we see fit.
That's how to win with these types of cards in a nutshell.
