Someone asked this:

I had to work this type of thing out in my head when I played bridge.

Assume you deal the SB and BB first, and haven’t dealt any other hands yet.

(The order that the cards are dealt doesn’t change the odds of what they get dealt)

The odds that the SB has JJ+, AJs+, KQs, AQo+ is 4.83 % and the odds that the BB has JJ+, AJs+, KQs, AQo+ is also 4.83 %

Now deal out 8 more hands, but don’t look at them yet. Have the odds changed? (No...)

Now look at all 8 hands (but not the SB or BB). Now the odd do change – for instance if all 4 aces are visible then the odds for the SB or BB having this range drop to 1.95%

(Since there are no A's left)

So if 7 of the people fold to you, it does change the odds slightly (If we assume that none of the folders had JJ+, AJs+, KQs, AQo+, then more of these cards may already be in the SB or BB) But we would have to run a lot of scenarios to determine how much the folded hands increased the odds of the SB or BB having a premium hand.

However, if we were just 3 handed, and no one had folded, then the odds are still 4.83 % until we look at our hand.

(When we look at our hand, the odds change a bit depending on what we have. If we have AA, then it is a lot less like that one of the blinds has an A)

But the odds of running into a premium hand to your left, are the same whether 10 handed with 7 folds, or 3 handed and no one has acted yet.

Basically, calculate the odds of running into a premium hand on your left as 5% times the number of players left whether the other players have folded or are sitting out.

*“If the action folds to me on the button in a 10 handed game, is there any reason to think that the SB and BB might have a better hand than if I am first to act, on the button, in a three-handed game? "*I had to work this type of thing out in my head when I played bridge.
