Identical board on two online tables, <<image>>
 

Please follow the link and look at the image.

I'd like to know the probability of such event, but that's not really important.

I mean it's not just a random board that happend to pop up on two tables at the same time. That board can make a heck of a lot of hands, and it wasn't until afterwards I noticed that the suits matched perfectly.

By the way. The boards made a straigt and a flush, but they both lost to full houses.

If u like I can post the hand history for both hands.

Please coment.

OK, P(2 identical boards)=P(flop match)*P(turn match)*P(river match)= P(flop)*1/49*1/48= P(flop)/2352.

P(flop)
We need a 6 of one suit, a 3 of the same suit, and a 2 of another suit. P= 4/52*1/51*3/50*6. 6 is 3 P 3, for different flop orders. P = 72/ 132600= 1 in 1841 and 2/3= 5.430E -4.

P(total)=72/311875200= 1 in 4331600= 2.309E-7.

so, 4.33M to 1. PS has dealt a little more than 1B, PP another billion and a half. so, probably a couple hundred same board hands dealt overall online (discounting folded before river hands and non-flop games).

People better than me at probability, how'd i do?

those are not identical.

Supposing we don't know any of the hole cards (let's say we are observing two tables), wouldn't the probability of one board matching another specific board be exactly the same as drawing a specific 5-card poker hand? Like the probability of drawing specifically a royal flush in spades?

Does it matter if you know what one board is?

Not exactly. First of all, the specific suits aren't the same, just the suitedness relations. and second the flop, turn, and river all have to be the same, not just the board in toto

Probability is approaching 100% if you play long enough.

I mean it's not just a random board that happend to pop up on two tables at the same time.

No. It is exactly a random board that happened to pop up on two tables at the same time. Nothing more, nothing less. (well actually something less, the suits are not exactly the same)

It seems you are suggesting this occurrence is evidence of something not right. It isn't. Strange coincidences happen all the time.
