Hero opens MP with 88 to 20 over one limper
Active villain OTB raises to 75. Limper folds H calls

H checks V bets 100 H calls
(360) Turn 5
bringing in the front door flush. H thinks for a minute that if the V checks here then he assumes H hit a flush and thus H will bet small on the river to get a crying call from over pairs. If V bets then he could be doing that with AhAx, KhKx, AhKx etc that are all in his 3-bet range.
So H checks V bets 175 H just calls.
(710) River Q
putting four to a flush. H checks again assuming V with the Ah, Kh combos will mostly bet here with four to a flush and less than a half pot bet remaining.
Is hero checking here the correct move? Or should he have taken a different line earlier?
Thanks.
