Open limp, ring games (no play content)

[leo doc]

I may be bordering on heresy here, but I gotta ask...

What hands, if any, would you consider open limping with in a "typical" live 10/20 or 20/40 ring game in the first three positions?

1) I have intentionally not specified what "typical" might be; feel free to define that yourself.

2) Aces, kings and, perhaps, AKs don't count 'cause you'll likely be re-raising with them.

3) Or am I really suggesting heresy here? (I.e., "I'd never open limp!")
