First hand; easy fold. Akqx or akjt or something like that I would call. Just wait for a better hand vs this maniac. What would you do post flop when hitting an ace...

2nd hand; fold. Usually I dont callt 3bets with an ace in my hand unless its a really good hand, see explanation hand 1.

3rd hand; mehh you can call, I prefer folding OOP though. IP I would call. If villain doesnt give you a hard time postflop its an argument for calling.

4th hand; Fold. Dont call 3bs with single pps unless it really connected and preferable DS like jjt9ds.

5th hand; Yeah call. 

Thanks a lot for posting this!

This is something i was also planning on reviewing  as well cuz i might have leaks in 3bet pots. After reading legendary's post i think i might have a huge leak cuz for me all 5 hands are CALLS! :-)

This is what i think:

1: ds which is connected, sb vs bb which means he 3 bets light, easy call

2: nut suit and IP so call

3: Since it is ds i would call otherwise fold

4: easy call with high pair ds and straight potential

5: not happy to play MW but since we are closing the action i would call.

I call all as well... Not  100% sure if there's some kind of nittiness level that would make the QQ hand a fold at this depth.

leaning towards folding in #5. dangler+we're facing tight range 3b. could be fold.

#2 depends on the villain. Nuts suit isn't enough to decide calling is mandatory. postlop tendencies would be relevant. 

would agree on calling in others, though I wouldn't go mad calling 'connected' AT64ds even vs maniac OOP. his aggro tendencies and us being oop are reasons to think on folding. we would miss often enough and he would 80%+ cbet. add to this having dominated draws and no real connectedness - close spot for me

Hand 1:

Against this type of player it makes sense with an openlimping-range from SB. Your fold equity is close to zero, and you will have lots of hands that you want to play in a limped or single-raised pot, but not a 3-bet pot. You're forced to play make-a-hand poker, so it makes sense to play smaller preflop pots on average.

The hand you have here should perform fine as an openlimp, although I don't mind your raise. As long as you make it to the flop, I'm fine with it. Raise-folding is out of the question for me, and I would openlimp this against the borderline insane.

I would call #1,3,4 for the reasons Imfish4u stated.

#2 I would call, since we are in position with a nut suit and our side cards can flop a 17 card wrap.

#5 I would probably fold. The overcaller may have better rundowns than us or good Kings which take some outs away. Basically I think that at least one player dominates our hand in that spot. I am not sure if position can outweigh this in a low SPR scenario.

 QJT4ss (Hand 5) is close imo. probably fold.

QQJ3ds is weird because of stack sizes, going the the flop we're going to have a SPR of 2.5. If it's not DS I probably just fold, but as it is i think it's a marginal call vs a tight player.

all other hands I'll be calling.

1, 3, 4 clear call

2 is close but I'd call; 5 is close and I don't mind folding
