102s, 276bb pot after the rake bovada 25nl

Ordinarily I don't really advocate XC'ing 3 streets, but I set this hand up so perfectly it must be posted. So IMO, and it might even be a fact, if you're going to XC 3 streets it should be against an overly aggressive player, but in general XCing 3 streets is a losing play as a whole, at least against most of my 25nl opponents (no idea for higher stakes).

Hero is 145bb deep BB, delt 10s 2s
My stats are
VPIP - 23
PFR - 17
AGG - 3.1
3BET - 5.5

Villain is 124bb deep and a spazzy fish best I can tell

VPIP - 82
PFR - 45
AGG - 3.5
3bet - 25.0

Hero is in BB gets delt 10s2s

UTG (Who is an extremely loose but passive Whale is UTG) min bets to 2bb.

Villain in MP1 calls
CO calls
Hero in BB calls

Pot is 8.5bb

Flop: AsQsJd

Great flop for me, gut shot for the nuts straight draw and a 3rd from the nuts flush draw.

Hero X's
Whale bets 4bb
MP1 (Villain) calls
CO calls
Hero calls

Pot is 24.5bb

Turn: 6s

At this point I'm thinking check or bet, but with the spazzy villain left to act, I'm gonna let him attempt to bluff this pot.

Hero X's
UTG bets 8bb
MP1 (Villain) raises 24bb
CO folds
Hero calls the raise (Ordinarily this should be a tip off to a made hand or an extremely strong draw as a best case scenario but we're not playing a poker genius so that's ok).
UTG calls raise.

Pot is 98bb

River: 5c

Just going to let him bluff, I see him capitalizing on the fact that he raised the turn that he might just bluff the river and think he'll fold out a lot of better hands than his meager holdings.

Hero X's
UTG X's
Villain bets 94bb
Hero calls 94bb
UTG folds

Pot is 276bb on showdown after rake.

Villain shows Kh6h pair of 6's and a missed gut shot at best

Hero wins the pot with a flush.

I pretty much check/call top pair to showdown as standard against a lot of aggro fish. It's far from a losing play against the right people at the right time, which is certainly more often than you are implying.

Also I'm not sure this counts as a CC x3 because you're calling a river shove, had he merely bet half pot you'd be raising this river surely. Check/calling first the flop with a combo draw and then the turn/river as a trap with the near nuts is a whole different ball park to check/calling for a marginal showdown hand.

As a standard, I'd be raising this flop, however against this guy I'm thinking that we're not so likely to get him to fold marginal hands, while there's a ton of value when we make our hand, so I like the flop call as opposed raise on this occasion.

I think you would do well to post marginal hands where you're not sure if calling three streets is correct or not.

This hand is clearly not a difficult hand to play.
