AA vs AK
AK ollin AA call
AA win 91.78%
You should think about it before you go to Olline.The stage of games and the stack plays an important role.
How often is this going to happen? Especailly without somesort of warning. (SHove/3-bet/4-bet) What if villain has KK? Then we have around 30%
equity. What if Villian has QQ/JJ/TT/99 ? Then we go to nearly 50% equity. What if villain has AQ/AJ/KQ? Then we are completely dominating.
You cant just assume your opponent will have AA or KK everytime you have AK (Actually since we hold an A and a K, we block several combos, making it much less likely) If you 3-bet or open raise with AK and your opponent calls instead of 4-bet/shoving, you can assume, the high majority of the time, he will have something you either completely dominate (Weaker Ace/King) or a Mid-High Pocket pair, which would be a coin flip.
Sure, if you have a solid read on your opponent and you know for sure he has Aces or Kings, go ahead and fold it, but most of the time, this will not be the case.
If you end up playing a reraised pot, stay aggressive. Just because you bricked the flop, doesnt mean your opponent has you beat. Remember hes mostly going to be playing big aces and kings or pocket pairs in this situation, so put out a solid c-bet to know where you stand. Its possible villian thinks you have a big overpair as well.
