welcome to donk-world
Nothing you can do about that one, man.
The
odds of anyone who is willing to play a 24 into your PF raise even surviving to be near the bubble is amazingly small. You would cripple your game if you start considering these wild out-of-the-blue sort of plays as legitimate. The donk got REALLY lucky (both in this hand, and in surviving to get to this hand).
BTW - I strongly disagree with the all-in push with that flop. Consider your opponents bet. He bet around 2/3 the pot, giving you almost 3:1 on your money to call. He's already indicating, by this bet alone, that he is trying to price-out any drawing hand, but that he's not sure if anyone already has the flush (if he had the flush, he would bet lower to keep you in). The problem for you is that you have to put him on either a set or two pair - both of which leave you drawing to win (either an A or for the flush).
I would say smooth call - keep him guessing - or even raise to 2000. Yes, you've committed almost 1/2 your chips, but it gives you the option of backing away if he pushes all-in after you, but still makes a clear statement of strength. If you see the turn, he acts before you anyway, so re-evaluate depending on what comes out.
