Estimating Ranges: Practicing

For the second hand -- if he's only raising 1% of his hands, that's basically KK+. I'd keep AQ/AK/QQ in his range until you see him raise something besides that range (or until his PFR% goes up).

Also, you should not eliminate so many of the Ax hands from his range. Lots of villains have a hard time letting go of paired aces. Especially on the flop -- keep in lots of those hands. Plus, he could have A3 on the flop, which would definitely continue to a bet.

Good job, though. I'm also trying to improve my hand-reading/ranges skills, and this looks like top-notch work.

To be clear, in the second hand when I said "I think he would raise these hands", I was referring to his opening range, not a 3-bet. But what do you think his lead-in range might look like versus his check-3 bet range?

Barring a few exceptions, I find c/r preflop to be an uncommon move at 2NL, especially for a 41/1 player. I think he's always leading in with QQ+ and AQ+, but might limp 99-JJ and then decide to 3-bet when the pot is raised. This... isn't based on much more than a "feeling".
