There is this absolute fish on my table 2 positions to my left. There's been like two pots that I've had to give away to this loose fish. I'm taking money from the rest of the table and I build up to 3x buyin... while this fish is redistributing my money to the rest of the table. Finally I get my hand: AQ 2 pair and i push it all in on the turn for him to call with a flush draw that hits on the river. Only a 100BB pot which is less than many others... but I don't think I was ever so annoyed. Thankfully I had to have dinner because I could easily have gone on tilt. Even though I was winning... any thoughts on how to stop this particularly irrational form of tilt?
