Folding A Baby Flush To A River 3-bet

[glorfindel]

1) If SB is a reasonable player: Call
2) If SB is a moron: Raise and call 3 bet.

Rationale:
In 1, the SB bet a flop that has 1 draw, the flush. 1 player raised and 1 cold-called. This immediately raises flush draw flags. The turn is checked thru. The flush draw flags just went flashing neon. The SB bets river when the only draw hits and 1 of the other two players were probably drawing to it. You don't want to have to call a re-raise against this player and if you fold, you will agonize about whether he had q10 or a whiffed checked raise set on the turn. Also folding after the river raise might cause other players to take pot shots at you. Call and expect to probably lose.

In 2, obviously a moron will bet and raise w/ anything and have no reading ability so you need to max value.
