5 handed, 5/10 limit

Folded to hero on button, raises w 77, sb folds, bb calls.

flop 4,6,10 rainbow
bb checks, Hero bets, bb calls
turn A
bb checks, Hero bets, bb calls

At this point I am thinking of folding to a bet on the river or checking behind unimproved. Who checks the turn? Who continues to bet the river?
