Waiting for turn to protect

[scott111]

3/6 B&M

2 hours in, table started playing very loose for past half hour, 7 - 9 to see the flop. Across from me are some lag types who have been bumping it with pretty weak hands so the pots are big. One them (UTG+1) really thinks he can sense weakness and reliably bets after a street is checked through. The rest are passive ATMs.

Hero is ATo in MP3

Preflop:
UTG calls, UTG+1 calls, 2 folds, MP2 calls, MP3 calls, Hero calls, SB completes, BB checks

Flop: T [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] (5 SB)
UTG checks, <font color="red"> UTG+1 bets </font>, MP2 calls, MP3 calls, Hero calls..

It could just be frustration sinking in, but I know a raise does not protect. I think that UTG+1 will bet the turn, So my line is check here, if a non [img]/images/graemlins/diamond.gif[/img] less than T falls or if I hit I raise him, else reconsider when the action gets to me. This way I exploit a bigger edge on the turn with less risk. Does p160 of SSHE apply here, or am I just wimping out?
