re: Poker & I need work on position and types of players
You have to be patient and notice, usually when im early in a tourney I play tighter and focus on how im playing to conserve my chips. from there to the middle I usually play a tighter range of hand that hit the flop well and I feel I can value bet.
I wouldn't focus on reading people too much because I moderate table moving and having to start back with no information on your opponents (unless you have notes on them from previous tourney's but always remember notes are subject to change as people get better)
Aggressive opponents are pretty easy to notice through them raising and shoving consecutive hands.
You'll notice more passive players by isolating them post flop and notice how often they fold to post flop aggression more often than they should.
