3 bet ranges for HU-nano.

Depending upon how stationy villains are preflop, and how often he open raises, 3b's can be pretty profitable. I don't have PokerStove on my macbook laptop, but here's my guess at a decent range without stove's help.

For a villain who has PFR of 40+, I have a polarized 3b range with about 30% quality hands (A9+, 22 - 99, some sc's and Ax where x<6). I don't like 3b'ing with TT+ unless the villain's really tight with PFR's, since I want to see several streets with an overpair. 77-99 are really good hands to jam with preflop, but can be scary post. Low pp's hold up pretty well vs. any but the nittiest jamming range, and the rest you can profitably fold except any big ace you think has a chance to be good.

At the nano's, hardly anyone jams or calls them correctly, so with a bit of patience you can jam pretty well with no fear. I hate calling jams until I have a read, but I don't mind a speculative jam early on from Hero. That's where 22 - 66 can be helpful.
