There's nothing you can really read. You just gotta think logically and play a lot and work on it.

"Ok he did this pre flop. He will do that with the following hands. A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P.

Ok he did this on the flop. Of the hands in his previous range, he will do this on the flop with B, E, H, N, O, and P.

Ok he did this..........."

And occasionally you will nail them down to there exact hand.
