I was once in your position, and yeah I had a shitty attitude, and yeah, I still do sometimes - but I have worked on it and am still working on it. I aplogize if my comment about your read was unnecessarily sarcastic sounding, but you do need to consider how blanket statements such as 'this guy is a noob' can affect your thinking in how you play a hand.

What I'm getting at here is by saying something like 'this guy sucks' or 'this guy is a noob' will typically lead to FPS crap because you'll have it in your mind that you can 'outplay them' regardless of your hand. If you don't wanna believe that fine, but I've been there and have had the same leak - only instead of discovering it while I was losing cheeseburgers, I discovered it while I was losing steaks (triple A ftw).
