Reality for me was > whatever one I enjoyed the most was going to be the one I'd find easiest to put the time in studying. (ie. in school I rocked Math but sucked in History, Geography & English. I actually liked math.. > = ez to study)
Lots of good articles out there on NLHE Tournament play. A good (great) start is to check out the Harrington books (Vol. 1 & 2) as they'll give you a good foundation to work from.
Some great articles to read are ones in the series written by Bond18 (aka "Tony Dunst") called something like 'the things it took me awhile to learn about Tournament play' (< not exactly sure of the title.. but that is close).
It includes a series of topics (parts 1 thru 18 I believe?)
stuff included like:
stack sizes & their relevance
Metagame - notes & concentration
Late Position Opening Ranges
Hand Ranges
Poker Variance
The flaw in Level2 thinking
Position
3-betting & 4-betting
Bet-sizing
Tournament Hand-reading
Playing as the BigStack
These ^ are some of the titles. This is an awesome series to try to get your
hands on. I thoroughly enjoyed it when I found it (yrs. ago) & always recommend it to anyone I'm 'trying' to coach.
gl on the tables! Hope you final table a few!
