I'm nearing the point of quitting live poker.
~97% of this is £1/2, with about 1% each of £1/1, £1/3 and £2/5.
I have bought in for the minimum (£50) at the start of every single session, topping up as and where appropriate, and rebuying for £50, £100 or sometimes £200 if the game is good
and I'm feeling good.
I play a relatively straightforward tight, aggressive game, very rarely outright bluffing, but semi-bluffing aplenty.
The games I play in are supersoft. I have tilted a bunch but can count on my right hand the number of pots over £100 that I've lost due to tilt, and I either had equity in those hands anyway or was sucked out on by the river and couldn't get away from my hand. I have just played bad in a few pots as well.
I try to do all the standard live game stuff - don't talk in the middle of pots, push my chips out the same every time (I'm hardly ever bluffing, though, so it shouldn't really matter), trying to pick up tells by looking at hands rather than faces, and looking to my left. I take regular (at least once every two hours, usually once an hour) breaks. I drink lots of water, and even sometimes exercise in the middle of sessions. I *never* talk poker strategy, or at least not good poker strategy, at the table. I don't berate other players and if other players berate me I usually just shrug my shoulders and smile.
Overall, I've been running pretty bad, and am quite near the point of quitting live poker.
