2-7 TD Heads Up

[Hosayif]

In Holdem for Advanced Players, Sklansky says to do this against people who raise a lot:

Preflop:

Call at least 40% of raised pots.
Reraise 25% of raised pots

On the Flop:

After reraising-
Check bottom 20% of hands
Check-raise top 20% of hands

After Calling-
Call more than 50% of hands


I was wondering, what are the top 40% of hands in TD with 3 draws to go and the top 25%? What are the top and bottom 20% with two draws and what are the top 50% (or slightly more) of hands with two draws to go?

Also, is there a free (preferrably Mac, but windows works too) program I can get that I can use to find out this stuff and to run simulations for 2-7 TD?
