I've always liked middle suited connectors like 78s. I generally play this type of hand in position when other players have entered the pot for 2- 2.5 bbs. When I catch on the flop I usually have the players holding Ax Kx etc in a bind. They find it hard to fold with middle range cards on board thinking their big ace or king will win it for them. And, for some strange reason, most of the time if an ace or king don't appear on the flop then they don't show up on the turn or river so I am fairly safe betting by suited connectors post flop.
