Flopping the full

Ultimatebet 10c/25c blinds my stack 2nd biggest at $38. AQo in cutoff seat i decide to limp, raised 50c by the button (the only stack that has me covered) mid position limper calls and i call.


Flop is AhQcQh i check to preflop raiser, and unfortunately he also checks. Turn is a blank I bet half the pot, and am called by the big stack. River is Kh making a 3 fluh in hearts on the board. I bet the pot and much to my surprise big stack goes allin for about $25 more.


Results to follow.


What should i have done at each stage? Preflop should i have raised? (sometimes i do, sometimes i don't with that sort of hand). What about checking on the flop? Thoughts on the turn and river?
