Raising second pair on a dry board is a significant error that turns a strong bluff-catcher into a hand that is only called by better.
Raising here is a major strategic error. Second pair functions best as a call to keep Villain's bluffs in and control the pot size on a dry board.
Note: Raising second pair here is overplaying our hand; we isolate ourselves against a range of Kx and sets while folding out the bluffs we beat.
Once we have raised and faced a click-back, we are priced in to call, but the initial raise has already destroyed our expected value.
Note: The 4-bet shove is unnecessary; after the click-back, we should call to see a turn, though the damage was done by the initial flop raise.
