Another char tip - announce your situation
My biggest leak still remains to be my inability to take my hand of the mouse and think things through. So a new semi-rule that I have just begun to institute is to actually announce my hand before I play it.
By announce, I don't mean just say I have AK here. I mean I announce the situation I am in to myself. I try and state everything that I think would be pertinent when I write a post describing my hand. E.g. instead of saying I have AK here, I would include my table position, my chip stack compared to the remaining players left to act, my M, what stage of the tourney we are in, any reads I have, any impressions I think the table has of me, and any other pertinent info. After stating that to myself and then making what I think is the best bet, I will take my hand off the damn mouse, wait to see what happens, and then go through the whole damn process if the action comes back to me.
I still think making rapid fire decisions is my biggest leak (and I would imagine others have the same problem), and I am hoping that this will help patch that leak.
