Reading Opponents

[Steven Punk]

Tired of lurking I figured it time to post.

My ring game is stronger than tourney and knwoing your opponent is important in ring but IMO it's way more important in tournies. For example in ring if I call a pre-flop raise with a pair of jacks because I know my opponent will raise from his position with a pair of 9s or better I have probably made a correct call and if I run into a better hand I lose X Bigbets but in NL tourney you are gone. Further there is more to read because players change starting hands based on limits, table, and stacks......making reads less likely to be correct or at the very least longer to feel confident on the read under the current variables.

Now when I play ring I have specific questions I want to answer about my opponents, like starting hands for example. How many and what are the questions I need to add to the list for tournies as compared to ring?
