Flop Analysis
Checking back is the most robust play. Our pocket fours have very little equity against a 3-betting range on this board, and we want to realize our equity for free.
When the preflop aggressor checks twice on a wet board, their range becomes capped, making a small pocket pair a mandatory call against river stabs.

Checking again is correct. While we have a slight equity advantage as a range, our specific hand is a pure bluff-catcher that doesn't benefit from betting into a range that still contains many overcards and draws.
This is a mandatory call. By checking twice, the Small Blind has capped their range, making this 15BB bet look very much like a polarized stab with missed draws.
