Check and call flop. You don't want AA, KK, QQ to raise...all likely hands for a weak tight UTG. Your hand is not strong enough to withstand a lot of action and there is a good chance you are not ahead.

Check and call turn. If you want to semibluff, I prefer betting. I don't know many fish who, after raising the flop and betting the turn, fold to a CR. Also, I think you want UTG+1 to call here.

River I think is close....check and call or check and fold...all depends on your read of this player. I don't know what hands you have beat here.

I think the above gets you more when you hit, and saves you money when you miss. A pair of 7's with a 6 kicker on the flop is not likely to win unimproved in a multiway pot.
