Although the odds against that are extreme, I think 50 million to one is a bit high.

I have only played two live tournaments in my life. In the second one, at the table behind me, 4 Aces lost to a royal flush.

Where's that bad beat jackpot when you really need it?

Assuming both players are all-in, it is apparent that the person with the flush draw has 1 out.

OTR there are 8 visible cards, so there are 44 unknowns.

So at that point, he has a 2.2% chance of winning.

But let's back up a ways...

There are 1326 possible Hold'em hands

6 of those are AA

So the chances of getting AA are 6 out of 1326 or 4.5%

Three of those have a heart, so we can only look at the 3 that don't.

The chances of getting AA without the A of Hearts are 3 out of 1326 or 2.23%

Of the remaining 1325 possible hole cards, 3 of them are

So the chances of villain having the particular set of KK would then be 3/1325 or 2.23%

The flop as described contains an offsuit ace, and a T to match one of the Aces

With the two sets of hole cards gone, we're now dealing with 48 cards, and they can be made into 3-card groups 17296 ways,

Exactly two of those are AAT where the T matches the suit of an A -- so 2/17296 = 0.01%

[3]
OTT: We're down to 47 cards, and two of them are part of the Royal Flush: 2/47 = 4.3%

[4]
OTR: 46 cards left, and only 1 suits villains quest: 1/46 = 2.2%

[5]
To find the chances of all these things happening on the same hand, multiple the chances of each step together:

0.0223 x 0.023 x 0.0001 x 0.043 x 0.022

or 4.7 x 10^-9 %

I'm not entirely sure how to convert to odds format -- X:1 -- from % when the percentage value is so small.

I'm also not sure at all if I did the math right.

50 million to 1 seems optimistic, really

All the best,
