So just a general question about 3-betting in live games, and I reallize this will be pretty table dependent etc. but I guess I'll just pose a few examples;

1)KQo on the button, dude opens in the HJ and is opening super wide, but theres also a really loose/bad player in the bb. We assume HJ wont be 4-betting light, but not like super confident in that read; we're all pretty deepish say $800 eff; 3-bet or flat?

2)95s on the button, same scenario as before only no fish in the blinds, I guess this would be more of a 3bet or fold for me.

3)A9o in the co, another loose opener (dif guy but whatever) in the HJ eff stacks probably 700; 3-bet or fold? (flatting out of the question?)

I guess some other general questions; do you typically 3-bet more w hands that can hit like a good 1 pair type hand (KQo/ATo etc.) or more suited low connectedish hands (75s/95s etc.) and how would this change based on you being in pos. vs. out of positions?
