I'm finally experiencing what you old timers call a "downswing." Atleast all these unpredictable opponents are teaching me to pay more attention and take more notes. For example, after this hand, I was able to calmly sit back, open up the note box for this player, and type in "[censored] YOU YOU LUCK ASS MOTHER [censored]. EAT MY ASS"
