hey guys, so I played this hand last week at a local casino. Its the main event of the spring poker classic series they just put on. Anyways,

The final table has two really really aggro players at it with alot of history with each other. There has been a  raise or 3 bet put in by one or the other every hand so far of this ft. The hand in question only involves one of these guys, Im told he used to hang with "the crew" of like 2004ish era? maybe i don't really know. I do know he plays professionally and is super agro. 

So anyways, table folds to me (we are 8 handed) and im in the cutoff with ajcc our blinds are at 3/6k 500 and i raise to 13000 with about 330k behind.  The dude described above makes the call out of the sb.  bb folds

We see three and its 4c 8r qc  he checks and i check back here as I have been doing here and there with both weak and strong hands. 

The turns peels the kc  he once again checks to me and i bet 11k, he tanks and raises to 40k. Still doesn't seem that out of the ordinary as he has been doing this the whole ft.(raising scare cards and dry flips) 

So i end up making it 110k here. he tanks and tanks and ends up calling

River is the mighty 8 of hearts... he checks to me.. and i?

my question here is how good of a spot is it to pile it in here? 

 seems like i have a ton of fold equity here but not sure of the range of hands he would be c/r calling with on that turn. 

Also wug thoughts on not betting flip?
