Effective stacks 2000
2 limps
Hero raises to 30 with JT89s from midpos
and gets 6 callers.

Flop 7c8s2s, none of heroes suit (210 pot)
sb checks and bb pots for 210, rest folds to hero who has 2 guys behind.

The guy who donks is a semitight rec player who likes to bet pot with mostly 78+ here. I have seen him call raises pretty light
but I dont expect him to ever be worse then 78/ Naked Nut-FD here as he bets into 5 guys.
The problem is behind me we have a shortstack with about 350 and a LAG who is a pro.

I am not sure what the correct play here, I have super-nitty image so IF I pot they will put me on 88 ONLY! Besides just calling is also tough with LAG behind.
And what to do on 8/flush that completes my straight. Is the play to fold? Since people dont mess around in big multiway pots so if I gii, best case scenario vs a set and worst case vs fd+set/straight draw.
