That's all there is to it.

Assume 100bb starting stacks. The BU is a nitty TAGG who does not 3-bet very much pre-flop and does not seem to call raises with a wide range of hands. He plays fit-or-fold post-flop for the most part. Assume something like 11/9 in FR or 17/14 in 6-max. The SB is a loose-ish TAGG (think something like 18/15 in FR or 27/24 in 6-max) who 3-bets pre-flop 6% and is capable of 3-bluffing OOP. He also leads a lot of flops, c-bets 85%, and c-bets the turn 60%, being very aggressive. The BB is a complete unknown.

It folds to our Hero pre-flop in the CO who raises to 3 times the big blind [1]. The BU calls, and the blinds fold. The flop pot is 7.5 big blinds, and the flop comes T 6 5 . Hero bets 5 big blinds [2] and the BU calls. The turn pot is 17.5 big blinds with 92 big blinds behind. The turn card makes the board T 6 5 J . Hero bets 13 big blinds [3] and the BU calls. The river pot is 43.5 big blinds with 79 big blinds left behind. The river card makes the board T 6 5 J T . Hero bets 26 big blinds [4], and the button folds.

We're going to use our answers in a later exercise.
[1] My range in CO to open, based upon the description of the players to follow, is 22+, Axs, A9o+, KTs+, KJo, QJs and sometimes QJo, SC's down to 67.

[2] My range now has narrowed a bit, but not much, I'd take out the QJ, KX hands that didn't pair, but the rest of the range is pretty much in there, this board is pretty dry so I'm probably c-betting about 80% of the time here.

[3] My range narrowed when the button called my c-bet. Now I'm only continuing with AJ, AT, TT+, 55, 66, KQ, Axspades, 89s.

[4] With button continuing to call, this forces me to be concerned he has hit a hand, and since he is nitty, yet not being aggressive at this point, I need to beat probably a pair of tens or jacks. That puts my range to 55,66,tt+, AJ+, AT, Tx. Unless I've decided to total bluff it, which I'm going to leave out a range for that, as it wouldn't matter, I'd say preceding range is most accurate.
