I probably check/call turn and either lead or check/call river.

On the flop I put BTN on a weaker K. I think AK would have reraised.

Turn kind of sucks b/c KJ just got ahead of us. I'd check the turn and call a reasonable bet. If he checks behind, I lead any river.

As played, call. If you induce a bet, you need to call it.

Vs some players I stack this off automatically; vs others I instantly fold. If your read means that he is a solid player, then I probably take the line I outlined above.
