You shouldnt be playing poker to "take flops" except for very rarely with Suited Connectors or small-mid Pocket Pairs when the pot and implied odds are viable. Also when you arent sacrificing too much of your stack to retain Fold Equity.
I disagree with this, unless you are referring to his stack size, because that is correct that with his stack size he doesn't want to be "seeing flops". However in general playing pots in position is a great strategy; and so conventional wisdom suggests we should ALL be seeing flops on the button in a higher percentage compared to other positions. (except in the case of the OP, being shortstacked the whole tourney position doesn't help you out much at all if you are all in preflop...)
Button is a great spot to be stealing open for 2.25 etc especially when folded to you.
This I agree with. especially if you are short it will look awfully strong. if you're extremely short (like 8-10bbs) it's a bad idea but if you have say 15-20bbs and it folds to your button you can raise 2.25bbs with garbage and easily fold to a reraise. If they flat you preflop and then check to you on the flop you can jam pretty close to 100% of the time and unless they were slowplaying 2 pair or better you should win a few medium pots that way, picking up about a 30% stack increase relatively risk free.
also, for myself I have increased my raising range from the CO and HJ a bit and eased up on my button raising range just a bit because I think button raises are just too obvious nowadays and even rookies know they are often bullshit raises. BUT, I have reversed that trend for calling a raise. I will call a raise a little wider on my button than I will from my CO for example, because I know I'll have the best position throughout the hand. It's much easier to play a pot without the betting lead when you have position.
So for example, I have increased my CO raising range to roughly 26% of
hands, and I have decreased my button raising range to roughly 32% of hands. So, I am still raising more often in the button than in the CO, but that gap is closing. I used to raise the button about 35-40% of the time if it folded to me.
I don't know if all those stats helped you or not. just things to think about. I agree that 1 tournament in isolation doesn't tell you a lot, but it's great that you are thinking about these things. Have you worked out your own opening and jamming ranges from certain positions? It is a useful and eye opening exercise to see just how trashy of hand you can jam from the HJ for instance and still be a +EV move...
