Surf, I think your flop checkraise is fine, but I think calling the flop has a lot of merit when there is a loose fish who will call 2 cold with a lot of hands (he's not folding any pair or straight draw and is probably calling with hands like unpaired Ax with backdoor draws) left to act behind you. Calling in spots like this is underrated. Calling also often prevents you from getting knocked off the best hand if it gets HU with aggro and he decides to 3bet the flop or raise the turn. It also lets him keep bluffing. You can also get away cheaper on bad turns or if the 3rd guy comes alive.

Protection is important, but it totally depends on how often you have the best hand and how many hands there are that fold for 2 but not 1...you also need to weigh this against the advantage of letting aggro keep the lead.

As for the turn, I think checking is the only play.

I think the river is close. I might pay it off because there are still some KQ/QT sort of hands that would fire again. IMO, you definitely need to be calling a 2-T river.
