*ahem* start playing 6 max. More hands = more $$$$$ *ahem*

hand 1) standard, bet sizing is fine. pot, 3/4 pot, use your imagination. If the game was generally deeper, especially the open limper, raising preflop would probably be better.

hand 2) I'd probably jack this baby up to $2 preflop but I'm a craaaaaaazy mofo. Checking is also fine and probably the more standard play. By raising, not only are you attacking the dead money in the pot, defending your blind, but you are also severely cutting off an opponent's implied odds if they have, say, 22. If you have AA in this spot, you're looking to get it all-in preflop on the majority of boards. KKx, JT9, and similar scary boards are obvious exceptions, ditto when the 12/4 nit starts playing back at you.

Looks like a solid fold on the flop. OOP in a multiway limped pot, this isn't much of a hand (especially if the game were playing deeper).

3) preflop = ewwwwww. Easy raise. 88 is like a premium hand here compared to the garbage you could profitably raise here on the button. If he check/raises you in a [edit: raised] pot, you can 3-bet push the flop or call and get it in on any turn (the former being probably more ideal because you could push a pretty wide range of made hands/draws as well).

4) yeah, fold.

5) Flop raise seems pretty standard. I wanted to check behind on the turn because that 4 is a pretty nasty card for your hand, and even if you're hand is still good (assuming it already was, which it may not have been), you will rarely get paid off by a worse hand now. He might chase his Kc though if he's really bad and doesn't realize that you could easily have 66 here. Highly player dependant I guess. I would fold preflop and not think twice about it.

6) figure out a way to get all-in on the flop while giving yourself some fold equity and trying to trap some dead money in the pot in the meantime. Perhaps bet/3bet allin, or check/push, or something. An option you may want to consider (and probably a bad one considering the nature of low stakes games and the fact that you probably want to keep variance manageable being a relatively new NL ring player) is squeezing preflop... ie making it $6 to go or something similar that you would do with a big pair or AK type hand. If called (especially by the original raiser), you would often give up on the flop unless you hit it big (ie NFD, aces up, tripping the kicker, etc). *to make it clear, I think this is a poor spot to do it with such a weak hand, hence why I would do it and feel good/badass about doing it*
