The key stat we need is missing: AF?

The 15/11 only defines a certain number of hands preflop, and on the fringes of that cold calling range (depending upon villain) is KJs and maybe A9s+ that might play this line.

You said in title he's passive. How do we know?

Why not? He could have KJs, easily, and betting TPWK with flush draw outs - which don't hit. Or he could have a naked King and think top pair is good.

The only two pair hand possible is KQ, and putting him on this narrow range even on the river seems silly - he could have a bunch of great draws and combo hands that missed and just be firing a weak bluff on the river to try to nab the pot. I'm probably betting the turn and check/calling the river. But I need more info.

There's a big difference between AF = 1.7 passive and AF = 0.3 passive, and we need to know #hands and AF to make any decent HUD read, here. BTW, 15/11 is reasonably agro preflop, so we need evidence to think of him as weak-tight postflop. A solid note or AF stats, please.
