I agree with yad and 4 2.. you need to bet the turn, But 15-20 (Isura-beavens) is too much.
you want to keep TJ or A in the pot.
20 into a 28 pot will force a weak A out.
12 (just under half the pot) in a 28 pot will keep all the draws in and a good A might raise you. if he calls you
42 in the pot.. bet 20 on the river.
