I was looking at the Harrington books and was trying to remember (took me a while to refind this thread for the book title) but IM sure these 2 books will keep nice and confused for a while
Actually I think you'll find Harrington's stuff to be a smooth read - well laid out & easy to follow. Also interesting enough to zoom through it, along with some key concepts for playing at different stages of an MTT (esp. Vol.2 where he gets into talking more about 'inflection pts.' & 'multiple inflection pts.')
For SNG play, Collin Moshmann's book - SNG Strategy is a decent read. I'd have to say it'd turn a losing micro player into becoming a winning player. It's not super advanco or anything but does lay out key fundamentals regarding game theory {which is a HUGE leak in ALOT of SNG & micro mtt (late stage play) players}. It makes it into my Top5.
