Hi,

It is interesting to know the probability for set over set.
Let say, we have pocket 2s and we hit set on Flop. what is the probability that our opponent has bigger set?

thanks.

I'm not a math guy, so I'm not 100% sure.

HU Poker. When Hero flopping set, chance that Villain:

- Holding pp: ~5% (according to chart)
- Flopping set: ~8% (4 outs x 2%)

So, chances are 5% x 8% = 0.4% Villain flopping set everytime Hero flopping set.
For 6max and 9max chances are higher but not too significant to worry about.

Hello Tarhonya,

what is this?
Is that mean when we have set of 2 and the probability that we facing higher set is 3.9430% in head up pot?

thanks.

Hello, sorry for the delay:

Three times in the last 24 hours I've lost with a flopped set-under-set. So I wrote a program to figure out how often this happens. That is, if you flop a set, it figures out how often at least one other player has a higher set on the flop. The following table is for nine-handed games:

I was a bit surprised. I didn't think it would happen this often with the smaller pairs (almost 1 time in 25 with 22). I'm not quite sure what to do with this information, if anything.

Update: The above numbers are somewhat misleading because the program counts all flops, not just ones with overcards.
Edit: forgot to add that this is from a random blog I found with the chart through google
