This is a discussion on Did you lose A k by 46 ? within the online poker forums, in the Learning Poker section; AK is a high hand but somtime when you flop with K and 46 , the opponent make all in you make call and lost
Yes, that's normal mate. Remember one thing. When You hold AK and opponets had two difrent cards he's got about 37% chance to win for example with 10 4, 8 5, or even 7 2 L] Try to isolate pre flop agressive players beting more pre flop.
I guess, you are asking, if we can fold in that situation, but you are giving very incomplete information. Like what are the stacks sizes of the players involved, what are the positions, what are the suits off all the cards, and so on. Without this information its basically just a bad beat story, which neither you or anyone else can learn from.
The think you have to remember is AK on a flop of A46 is top top but its not the nuts. So many players will put 100 or 150BB in the middle with that one pair and never think of the possible hands the other player could have. That is a good recipe to go broke with.
