    Long time lurker on your lovely forum. I was hoping one of you knowledgable folks could help me out.

    I saw AA v. KK all-in preflop hand today and I wondered would the KK have any better chance than 22 in that situation (probably a minuscule one I thought). I lashed it into an odds calculator and this is what came out:

    cards %win %lose %tie EV
    As Ac 81.06 18.55 0.38 81.26
    Kd Kh 18.55 81.06 0.38 18.74

    cards %win %lose %tie EV
    As Ac 81.30 18.20 0.50 81.55
    2d 2h 18.20 81.30 0.50 18.45

    Note: I put each pair with different suits so that the aces dont have a direct flush advantage.

    But, now that I think about it, I can't figure out why the KK has any advantage over the 22 at all or why the 22 has a better chance of a tie (au contraire mes freres, it seems to me that it'd have a worse chance because if the board came a complete flush - either d or h - then it'd be a split pot cos the 2d or 2h wouldn't count?).

    Could someone kindly point out the error of my ways?

    Flushes.

    If there are 5 hearts on board and you have the K it will count. If you have the 2 it won't. Therefore higher chance split pot, lower chance of win.

    Also...
    With the KK, if the board has a K on it then excluding flushes or straights, the A needs to hit.

    With the 22, if the board has a 2 on it, the AA can still win if the board finishes up having trip 3s, 4s, 5s etc.

    It's only a tiny difference.

    22 and KK affect the probabilities for the aces making a straight, equally.

    Jesus christ and I basically spelled out why the 22 flush wouldn't count on a fully flushed board in my question...

    Back to the lurking. ...

    Thanks.

    True... hadn't thought of that either.
