Me personally I make moves, with my cards or even against the player, the latter is what most people will tell you is more important, you gotta be prepared to risk, thats poker... I try avoid having a stack where its shove or fold even though I find it a very strong part of my game, I just hate having to go up continuous coinflips or being sucked out on just cause you don't have enough chips to induce a fold from a big stack that would call you on a wide range of hands.
Aggression is key imo could be wrong
Gotta have the right image also, the fact that you could have a TAG image could go a long way in semi bluffing pots etc in the later stages.
Theres a few things more I could say but I'm sure someone else will fill in the blanks on what I have missed/notmentioned at all, but yeah this concept seems to be working for me at the mo.
