all these hands really depend on your in game reads and game flow. what is your opponent like etc. all this info is really important to determine the best action against him
it looks like you are taking a lot of risks hu, which is ok, but you need to pick your spots and make sure you are not wasting the hu by taking on huge all in risk spots when you really need to make the hu count and win it!
also, convert the hands in a hand replayer,
or alternatively into a hand replayer
in regards to your hands. here's what i would default to if i joined the game with absolutely no reads at all.
so much play left in this one, it's such a big risk for a mediocre reward. i'd default to flat calling here and playing this postflop, we're oop, but we can do some funky things postflop. i wouldn't expect a normal average player at this stake to be raising atc here on the button, so i'd be looking to take pots away postflop. also, we have a hand that flops really well.
i dont think shoving is a mistake by any means it's most likely +EV, theres just other ways to go about things that don't risk your tournament life for a small gain relatively.
this one really depends on who is in the blinds, we could make cases for limping, min-raising and shoving or folding. i think the option i'd likely go for is to limp and stab at flops. our hand is ok, but it tends to get dominated a lot when called. i'd much prefer to shove this with safe hands, like 85s or 107s.
if he's definitely on ATC then Q4s is probably an ok call. we're so far behind in the tournament, and folding too much here is really bad for us, so we need to find an all in situation. if i think he's ATC then i call here too. if he's not, then it's a definite fold.
