Flop Analysis
Standard call with top pair. We are ahead of SB's wide range and there is no need to raise and isolate ourselves against better Kx or sets on such a dry texture.
Defend wide preflop and use your top pair to extract value when the aggressor caps their range by checking the river.

The 4s is a total brick. We continue to call to keep SB's bluffs in and protect our range, as raising would mostly fold out the hands we beat.
When SB checks the river, their range becomes capped, missing most of the strongest Kx and sets which would typically continue for value. Betting is correct to extract value from Tx and middle pairs.
