well you chip stack and your position is always going to determine how you play a hand even if its aces for example if your early to act usually a smooth call is not a good move cause your sure to get a few limpers and an almost guarantee of a two pair on the flop (so you play fast and big not nessicarily a shove but put their roll on the line as well). And in late position if everyone folds to you a smooth call can be the best option here to make sure 3 to a flush or straight dont show up on the board or even maybe get lucky and pull a set and slow roll em. But position is more basic strategy not so much to do with your bankroll but on short stack bigger hands are usually always push hands and pray. and smaller hands are surefire quick mucks and by smaller hands i mean starting hands like k-10 (it is a weak starting hand especially in the top 50 of a 5000 player tny) so only play larger strting hands aq ak or large pocketpairs 9-9 and higher.
