credible bluff?

[Riverrun]

villian is 22/8/2 over 175 hands. my image should be solid. i've recently won a big pot vs. another opponent where i just called flop with monster and raised the turn and fired psb on river. haven't gotten out of line. i'm like 17/14/2 this session.

if you don't like this, what do you think he's calling with? do you like this less with the heart draw out there? i figure i'm repping KJ or 999.
