You just need pay attention on stacks, u can steal from SB, Buton, Cutoff, even Hijack, if the cutoff, and buton are tighers. Better steal when they have a medium stack, but becarefull whit re-steals, they can do it
bluffing, or whit really value, tribeting, or going all in, so u need to fold if u dont have a good hand.
In case u have a short stack on u lefts, like 6 - 10 big blinds, looking for shove every good
equity hands, like every Ace high, or Kings suiteds, QT+, broadways, etc, if they fold, u steal the blinds, and if they pay, u almost always in front to win.
U can observe too who is stealing u blinds, if u have a agressive player, on every final poistions making raises to steal, try to make a re-steal some times. Agressive players is better u shove all in, otherwise u can took a 4bet from they, if is a tight player, u can do a 3bet light and he fold. Look to do it whit any Ace on hands, or broadways, so u will have a blocker card ( if u dont know what is blockers card search it on forum, its nice to learn too).
Finally, if u make a steal and he pays, u need look the texture board, and c-bets dry boards, whit any high cards for u represent, u can C-bet too semi bluffing, if u have some draw, or any pair, some boards u can do 2 bets, o flop and turn, if appear some high cards on turn, or something that helps u.
Hope help,
