KQo - TP on monotone flop facing turn action

[pokernicus]

There aren't too many cases where I'd call a bet and fold to a raise on the same street, but this seemed like a reasonable situation to do so. Comments on all streets appreciated!

No reads on individual players. Game is reasonably tight with most pots being heads-up or three way.
