Does anyone know of any good, well-written guides out there to working on reads? Have any strategy?

My reads pretty much stink, especially in 6-max. I never believe that guy flopped the nut flush on a 3-suited flop. Yeah, that guy must have the ten every time on a TT8 board, my jacks are no good. Etc, etc.

I make some solid reads. I've seen the flush draw call the pot on the flop, then bet 1/5 the pot on the turn enough times to know to make a big raise. But I still can't tell if that guy pushing the third card to a flush really has it.

I know a lot of this is playing thousands of hands. But in my year of playing (it's been a year now, happy bday me, I'm still winning) I've played many thousands of hands, and I'm not happy with my reads.

They say some of the professionals like Negraneau and Harmon have uncanny reading abilities. That's what I want; like playing with a marked deck.

Anyway, got a place to start?
