Just finished reading Dusty Schmidt's book and experimented with a few new concepts in my next session.
It went exceeding well and I think luck, playing in position and focus played a big part. I did feel a bit of a fraud at times, I was even slightly guilty taking a full stack off AA, QQ, AQ. But good variance shone on me with the cards, thankfully I realise it and it makes up for the bad times I was having a few weeks back.
Will stay tight again for a while, so as not to squander my ill gotten gains. But perhaps mix it up a bit just to be more unpredictable...
