Hero, seen as very tight and beginner (don't know how to cut chips, etc.), about 70BB
Villain, probably a good regular with a huge stack
I raise to $15 from EP with AsKc and get one caller on the button.
say Pot is $30
Flop comes Kd4c8d and I bet $15. Villain calls. Pot is $60.
Turn is 4s. I bet $30 and get called. Pot is $120.
River is 9h. I check and villain bets $50.
Should I have bet the turn at all? and should I call the river? How good pot odds do I need to call the river?
