Odds of single opponent having pair or better?

[Isles]

I don't know how closely you can get to this answer /images/graemlins/smile.gif

If you are playing against 5 opponents, and you raise preflop, and get one caller, what are the odds that this single opponent has a high pair or better by the river?

High pair can mean top pair on a low board, I simply mean a legitimate reason for someone to call you down.

Is this an impossible question?

How about just a ball park? /images/graemlins/crazy.gif

What range of hands do you put your opponent on. This can be calculated easily for a specific hand...for a range of hands, it's more difficult.

I am limiting my "solid" opponent to whatever hands they will call a strong raise pre-flop in NL, six handed.

So for arguement's sake, let's say:

1- any pocket pair
2- any top two from JT-AK
3- connectors from 56-9T

Should be roughly 22% of possible hands.

If I can get an estimate for a "solid" player, I can slightly increase the percentage for a looser opp, and slightly decrease the percentage for a tighter opp.

Not even a ball park? /images/graemlins/grin.gif
