4. 98s - definitely fold this preflop. Suited connectors play well in multiway pots where you can limp in for a small amount, rather than where you are calling raises.
6. 84s - fold to the flop bet. The reason to fold is because there are three players still to act, and if two of those shove you'll have to fold. As played, I haven't run the EV calculations but since this is a SNG you need to use $ EV not chip EV for a proper calculation - my guess is that it's a marginally bad call
7. ATs - fold preflop, this would be fine as an open raise but with the limper in front I just let it go and move on.
8. 87s - fold this from UTG rather than limping. If somebody raises after you, you have to fold and you wasted 60 chips.
Q K SB (Hero's M = 9.33; f+f+f+f+r+F+c+s+b+f) (between 8 and 9) - could be a shove over depending on the size of the raise and the raiser's stack size (and reads of course)
9. 33 - fold preflop. Your stack is getting low, and if anybody raises after you, you have to fold. When your stack gets below about 12-13x BB you need to be thinking about shoving or folding preflop and this wouldn't be a good shove from UTG.
11. AJo - raising is fine, but I'd make it 300 not 360, that's plenty. Saves you 60 chips if anybody shoves over.
12. A6o - I don't hate this but I typically just let this go from the CO.
13. Q9o - don't like this raise. Just check and see if you can flop something nice. As played c-bet is good (sizing is good too).
14. AJo - shove it preflop if you want to play, if one of them calls you are basically committed to the pot.
15. 22 - fold preflop, these baby pocket pairs are good when you can limp in for cheap and try to hit a set on the flop but not good when the blinds are higher. HATE the limp/re-raise - you have NO fold equity against the raiser since his first raise was 40% of his stack, and you're either flipping or dominated against whatever he has. Just fold and move on.
16. A3o - I'd fold this from UTG, mostly because the other big stack is in the blinds.
18. Q9o - I actually like this, because the limper isn't the short stack so unless they're a maniac they won't call wide
Q 6 SB (Hero's M = 17.42; f+f+F) (between 18 and 19) - put the short stack AI here
19. 87s - fooooooooooooooold preflop, particularly agains the big stack. As played, check the flop, even though you have an open ended straight draw that's a bad flop to bet since that is very likely to have hit opp's range. DEFINITELY fold to the minraise and DEFINITELY check the turn and give up to any bet. I'm sorry to be harsh but you really committed suicide on this hand against the second stack.
2 K SB (Hero's M = 4.94; f+f+F) (between 20 and 21) - definitely shove this.
21. 53o - unlike hand 18, this is different because the limper is the second stack and can afford to call you and not be crippled or out. Check it and see if you hit a good flop.
2 6 SB (Hero's M = 5.28; f+f+F) (between 21 and 22) - definitely shove this.
