Hero is BB with A
A few limpers pre flop, SB raises to $10.00. Hero calls, MP 2 Calls, Button Calls.
Flop: 4 players ($44)
A
SB Checks, Hero Bets 25.00, MP folds (after thinking about it), Button folds, SB Raises All-in (90.00 total), Hero...?
SB is my nephew and plays pretty TAG. I have him covered here, but only by about 45.00. His normal preflop raise with solid starting hands is 10-12, so his preflop raise doesn't really tell me anything. When he checkraises he usually has a very solid hand, but I am not sure what I can put him on here. My initial thought is AK, but I am not positive.
Is top two pair on a rainbow board with no real straight draws safe here? Easy call or painful muck?
