Should I be here in the first place?

Hi guys any help is appreciated. Are these okay or should i just always be avoiding these spots 100% of the time and not mixing it up this much at this level. Both villains were unknowns as I'd recently sat down on both hands; no reads other the original raiser on hand one opened 3x very lightly fom all positions. No commnets from Marshall please.

I think the only mistakes are preflop and i'd probably fold hand 1 to the threebet and fold hand 2 to the threebet as well.

hand 1- fold preflop more often than doing this but this is ok sometimes. problem is you have to call off 70bb with AQ if he shoves pre which isnt the greatest feeling. If you think u have FE with this raise size, id rather make this play with 27o. With AQ, youre actually forced to stack off after 4betting so id prob make it like 35.50 instead of 28 to possibly gain some additional FE.

Hand 2- again folding pre is standard but hell if im battling someone im calling this 100%. As played c/r all in on flop tends to get more value unless hes retarded aggro because he would probably take a b/f line when he's missed with overs whereas vs your donkbet most people are just folding rather than jamming those same overcards so you miss a bet. Youre not going to fold out any pair that he 3bet pre for value such as 99 and TT.

postflop is good pre is like 5.5/10

Definitely c/shove on hand 2. You want to pick up a continuation bet if he's bluffing.

1) as played preflop you dont really have any other choice than to bet/call flop. but yeah like others said fold pre. i dont think cold calling is terrible, but it puts us in a lot of awkward situations imo.

2) easy fold pre. and as marshall would say, i like a check/jam here.

lol I love the way you got a real indepth response out of nuts. wp

Thanks guys and yeah Nuts will always give me in depth replies sinc ehe knows me as his biggest fan...Missed both my draws in these fuckin' hands but that analysis is pretty much what i thought and the 4 bet with AQ is something I NEVER do. Just felt like going a bit crazy to see if i could make him fold anythin that wasn't AA or KK turns out he had KK...oh well. Thought cos that dude always opens with his weak little 3x raises that the 3 better could be doing it lightly. Hand 2 - i jus thought too much about the fact I had suited connecting cards and that we were bith full stacks - always think I'll stack the guy in these situations for some reason. He had AA.
