Without additional infos. You can just safely fold preflop.
A squeeze can be a good idea in two kinds of scenarios:
1) most opponents will fold to it. So, as probably CO and certainly SB are not slowplaying, if MP is raising wide enough and folding enough this could be a decent bluff. Not the case in most of microgames since all the 3 guys should be regulars
2) isolating vs fish. Again, no info here, but for instance, if SB is a fish you can raise for value (still MP and CO needs to be regular)
Ok the cbet on the flop. You have 2 overcards and backdoor NFD. Turn is a total blank, we can safely chec/fold
Little bigger otf or x. If you cbet, double barrel vs this villan. Thin value bet a non heart T and xc an A would be my plan otr. I probably fold pre though a lot.
CO and SB were fish and MP was opening a lot. So i thought he could fold and i could be in a hand vs fish where i might dominate them/be ahead.
I think MP's range is 44-TT because he thinks a fish behind him might call so he gets better odds with PP and since he opens so much he should be defending quite some hands vs3b. Also KQs and o, AJs and o, AQs and o, KJs, TJs something like this i think.
Only would squeeze if expect lots of folds (bot V's high Fvs3B).
If called I would X-F or barrel multiple times but not one c-bet then give up since a large part of his range consist of 77,88,TT,JJ,QQ even AK/AQ might float your bet.
