It's easy with 2 hands all in. However when there is an A,B, and C hold em hand preflop how do you calculate a specific finishing order, such as A in 1st, B 2nd, and C 3rd?
Maybe there is an online calculator that does it but I couldn't find it. Thanks

Cycle through all 5 board cards, that is 46!/(41!*5!) = 1.4 million showdowns. Sum up all results in the 10 possible categories, and you are done.

Poker Odds Calculator
If PA1, PB1, and PC1 are the respective probabilities of each player finishing 1st, then the probability of player A finishing 2nd and 3rd are (ignoring ties):
PA2 = PB1*PA1/(PA1+PC1) + PC1*PA1/(PA1+PB1)
PA3 = 1 - PA1 - PA2
Put this in a spread sheet I suppose if you want a program to do it for you.

This isn't what OP asked I think. He wants specific breakdowns of how often each hand will finish 1st, 2nd, or 3rd. Unfortunately, I am unaware of a program that does this calculation for you.

I'm pretty sure this would be inaccurate. Probability for A cannot be for 2nd and 3rd, it has to be the trifecta for the mid stack to go out in 3rd considering the stack sizes. Or maybe I am misunderstanding
Do you agree at least my formula for PA3, the probability of player A finishing 3rd, is accurate?
As far as the formula I'm afraid it's a bit over my head
Player A:300k
Player B:150k
Player C:30k
I am player B so the only way I get eliminated IN THIRD PLACE is to get beat by player A who also either ties or gets beat by player C in this same hand
For that to happen, C has to have the best hand, A the second best, and B the worst hand. If A had the best hand both B and C would be out but B would get 2nd place because of the higher stack, regardless of whether C beat his hand
However, your original question had to do with the trifecta (to use your expression): you wanted to know the probability for each player finishing in each place. So you are correct that the generic formula should take the specific stack sizes into account. One could work this out using a spread sheet with not too much work involved.

The answer to your question is to use the same formula as before but B and A swapped:
PB2 = probability player B finishes in 2nd place
= PA1*PB1/(PB1+PC1) + PC1*PB1/(PA1+PB1)
PB3 = probability player B finishes in 3rd place
= 1 - PB1 - PB2
PA1, PB1, PC1 are determined from the link given previously.
Since you have specified the stack sizes in your example then the chances of Player B finishng 3rd is the same as having the 3rd worst hand. If you wanted a more generic formula then you would have to include the actual stack sizes in the formula.
Quote: tringlomaneI finally did this in pql at propokertools.com, but I think you got rid of the specific hands in question in the posts. If it is still AT >= AK > 88, then that will happen about 7.66% of the time. It obviously depends on the actual hands though.

Perfect! Thanks tringlomane. Actually I didn't say that the A10 had two live suits but I doubt that would have made much difference since there would have to be an A or K on the board also for AK to beat 88.
Paisiello I appreciate your answers also. Your equation might work also, I don't know
