Hi all. im 17 and have recently improved my rank to the mid 1500's. i really do hope to get into the 1800 sometime this year. so im wondering if people can recommend some good books, videos or online websites ect, that i can study/learn from to improve my playing. or if anyone has a good study plan they would like to share.. All opinions are welcome and appreciated =)

John Nunn has two, compact, excellent new books--Understanding Chess Endgames, and Understanding Chess Middlegames.

Lots of bite-sized examples to play through, and become a "Killer."  

haha cheers! i'll definitely look into that :)
