I find I used to go broke a lot with the second hand you posted. Especially when opponents are a lot tighter preflop from the BB. They call with too many aces there so that a call down like this is not profitable.

What level are these games at? I think that matters greatly to your general question, maybe not so specifically to these hands, though on the second one in a lower buyin game you can often call and check behind or call a weak bet on the river and win much of the time, people raise in very random spots in lower buyin games at times, or raise flush draws on the turn, a king in that spot, ect. You get zero credit in raised pots often in lower buyin games.
