post flop odds please

a9 vs 10/10 flop aa10. can some1 settle an argument about the odds of a9 winning this? i can approximate the odds for the obvious 4 outs (a999) this being about 16%. the debate was over how much to add for the possibility of river pairing turn. shouldnt it b less than 1% (45 cards left so my rough math was 6% of 11% or about .7%)

Why are you trying to work this out yourself? Just use an odds calculator.

because im pretty new to the online scene...old and technologically impaired...looked around for something like that but only found 1s that would allow preflop calculations...where do i find something like what u posted?

A wild guess?
Type "poker odds calculator" into Google.

After the flop the A9 has 4 outs for the turn (A999) but after the turn (assuming no A 9 or T) the A9 hand adds 3 outs for a total of 7 on the river. I use PokerStove: Poker Software and Analysis for equity calculations like this. The one above can be found by looking at the table in the pic.

If you want to do a rough calc in your head then something like this:

4 outs on turn (1 ace and 3 nines) and 7 outs on river (1 ace, 3 nines and 3 of the blank turn card to pair the board).

When doing different outs on turn then river i use 2 x turn outs + 2 x river outs = %. Whether or not other ppl use this i have no idea but i was very bored on the bus home from school one day and decided to figure out something that worked for outs that change on turn/river and this seemed very accurate.

So (4 x 2) + (7 x 2) = 22%

And yea if you compare it to the calculator it is a pretty damn good estimate that takes about 5 seconds to figure out.
