A hand from SSHE would like discussion

[sparky3474]

A hand from page 96/97 in SSHE, post flop play, "hero (Qh7h) has made two mistakes, the worse one being post flop". The flop is Jc, 7s, 5h and Hero, in MP, is sitting here with 6.5 outs (two 7's, three Q's & bdfd), an overcard, middle pair and a decent kicker. There are 10 sb's in the pot and it is raised to him by the preflop bettor (11 sb's now) and he calls yet Ed says raise. What pushes this to a raise situation, the pot is fairly big, there are straight draws out there, if he puts in 2 bets he will only be getting 5.5 to 1 a little shy of the 6.5 to 1 that we would like? Can we generalize here and say with a middle pair and getting the almost correct pot odds to play we should raise? If your drop back a little and say have 5 outs (8 to 1) (no bdfd) with and without another flush draw out there what do we do?
