I have some sessions with a UK pro every now and then and he gave me some range charts to study for open raising, but I feel out of my comfort zone using them. I wouldn't normally open with 9Ts and from UTG with a 20BB stack. Maybe I'm playing too tight, but I find it difficult to play some of the hands post flop when I connect with the board. I feel much better 3-betting hands like JQo in position.
