I like it... a lot

I know my river range here and if I folded this, I folded a better hand... Cause it basically includes

Occasional 56s type hands (which have a striaght)
AK diamond type hands (which have a flush)
or.. pairs higher to or equal to yours...

You raised the river really quickly too on a card that I thought may have been scary to you as well (the 3rd diamond came in, and I didnt raise you on the flop, but on the turn).

River bluff raising is normally -EV against me, cause im a SD monkey, but here it's a pretty good spot.

BTW RZK, the reason river bluff raises like this are so effective is because people dont play optimally.

The key idea is this: A solid TAG vs a solid tag, is never re-raise bluffing this river.
It's re-raise bluffs that kill strategies such as this... But because they are so so rare in practise, that raising in spots like this is an exploitable, yet effective play.
