Why is 56s best hand against pocket Aces?
Was wondering why 56s has higher probability to beat AA than slightly higher suited connectors (e.g., 67s. 78s, or 89s). There is obviously a reason but intuitively, I'm not getting it. The way I'm thinking about it, 56s and 67s have smaller chances to make a straight than 78s and 89s because there are already two dead aces pre-flop (so less chance the board will be A 2 3 4 5 or A 2 3 4 6). 78s and 89s have all of their straight cards available (though would still lose on a straight on the very rare occasion that AA hits higher straight or better). Is 56s the best hand simply because the 5 takes away some straight possiblities from AA?
