2 river value bet questions

[NinaWilliams]

Hand #1 cap preflop. You have a nice equity edge, so push it. Dont donk the flop, its never getting checked through and i want to see what bb does before I put chips into the pot. As played, ya bet the river. Hes never folding a pair here and a king is unlikely. You can fold to a raise.

Hand #2 I dont think your hand is strong enough to raise the turn, but if it is, why isnt the river an easy vb?
