PREFLOP: This is a fold in almost any game type but especially in the loose aggressive game you are in. Playing ATo out of position against a lot of tricky aggressive players cannot be profitable IMO. FLOP: Good raise, since you have to call, you should raise to help possibly clean up your ace outs. Turn: You have a vulnerable top pair hand in a large pot and someone just bet into you, you must raise to protect your hand here, not raising here is a great sin. By just calling you allow any gutshot or 5 outer to draw profitably against you, you cannont alow this. Protecting your hand here with a raise is more important than worrying about if the SB has a better hand than you. RIVER: Youre getting 18.5-1, this is a must call, so this is standard, you only have to win a little over 5.1% of the time to make this call profitable.
