(Hey, look, a post not about Party.)
1) I need to play higher than 10/20 when playing limit live. The slower pace and still very emu-esque play frustrated me a good bit. It may partly be due to some of the bloom coming off the poker rose for me, but I definitely didn't feel like I was achieving anywhere near an equivalent ROI playing 4/8 and 10/20 live, and that the general play was still bad enough to negate some of the advantage of knowing what the hell I was doing. Yeah, I know, you get bad play at all levels, big hands get cracked by junk everywhere, etc., but if I have the bankroll and the time to play, I should play at the highest limit I can comfortably swing.
2) On a related note to #1, I have to get over the psychological gambling hump as far as playing with real dollars, in a live game. I don't have this hangup online when it's virtual money, but my sphincter tightens when it involves actual paper money exchanged for chips which are then (hopefully) exchanged for more paper money. I probably should go ahead and withdraw some cash from Neteller and keep a larger physical cash bankroll for live games. Yeah, I can hit the ATM, but that's psychologically destructive, not to mention a strain on marital bliss if chunks of money start disappearing from our joint checking account.
3) Reads are easier live. (Duh.) Which is nice, but it also includes an even greater obligation to follow through on your reads, no matter how painful. There were two different instances where I absolutely, positively knew I was beaten, even though it meant that someone was about to crack a set of mine with a junk hand like K8o or 59o. Yet I managed to concoct reasons to call it down both times, only to see exactly what I knew they had.
4) Quit when you're tired. I've mastered this as far as online play goes but one night I insisted on playing long past the point of sharpness, for no reason other than to maximize my chance to play poker live. Yes, granted, living in the midst of Texas kind of sucks as far as live play goes but Vegas isn't going anywhere, nor is Louisiana, and there'll be plenty of poker to play in the future.
5) I still need to play much more live poker. I'm not as aggressive live as I should be, as far as making moves or re-raising when I think I'm marginally good, for the very simple reason that I don't want to look foolish. Online, sure, what the hell, as I can hide behind lovely anonymity when exposed as being full of shit, but I'm still hesitant to make plays I know I should live.
6) I need to talk more. Quiet guy who pays close attention and plays very few hands = scary. Loud, obnoxious guy who keeps knocking over his drink, always raises when he plays, and never knows when the action is on him = action. I'm never going to be loud, obnoxious guy but I also don't have to be quiet, scary guy.
7) Table selection applies to live games just as much as onlnie games. Yeah, it's a pain to re-rack chips and find another game but that's what all those poker tables are for, especially if you're in a room with other available tables. Whether it's rocky conditions or one hell of an annoying frat boy WPT-wannabee, there's no reason to sit there if you know there's a better table somewhere else.
