Standard line w/ 77?

[soweak.]

Just wanted a line check here, comments and criticisms are always welcome

Party 3/6 10 handed.

MP3 player (typical TAG after about ~100 hands) opens in MP3. Loose/Passive fish cold calls on the button and I call one more bet in the BB with 77o.

Flop is 2d8s9c (6.33 SB). I bet, TAG raises, fish folds, I call.

Turn is 9d (~5BB). I bet, TAG pauses ... then raises, I fold.

Standard?
