I got this today. Very welcome, but I'm no good at extracting money off of a scary board when I have the nuts.

Q8 suited, one off the button. A few limpers so I limped. Flop comes:

Q K 8 (2 hearts on board, I have none)

I bet the pot after it was checked to me, one caller (button)

Turn is another Q, giving me FH. I bet half pot, trying to make it look as though I was scared of the Queens and his call earlier. He raised to the pot and I called.

River is the last Queen, quads. Given he raised my earlier weak bet, I put out another half pot bet. He folded. Any tips would be welcome. It was a 0.05/0.10 game.
