*** HOLE CARDS ***
Dealt to Hero [7 4 T 2]
pot man I: folds
Villian: raises $4 to $6
Hero: calls $4
Hero makes a standard call from the big blind, as I will with a wide range of hands. This is a weaker, speculative hand, but if I hit an Ace, I'll have a good chance for a low draw and opponents who has an Ace will be less likely to fold. Villain hasn't been at the table long, and hasn't done anything noteworthy so far.
*** FLOP *** [K A 8]
Villian: bets $11.40
Hero: calls $11.40
A good flop for me, as I now have the 2nd nut low draw and a 7-hi flush draw. This is the type of flop I was looking for. Given that everyone folded to the small blind preflop, it's likely that Villain has an Ace. Raising and calling are both good options here. The benefits of raising: I might get him to fold some hands I want him to fold and I make sure he can't get away and fold if a heart comes. The benefits of calling: I can get away if a bad card hits, and I get more information from how he acts on the turn before I commit a lot of money. I decide to call.
*** TURN *** [K A 8] 
The turn is an excellent card for me, as I now have the made 2nd nut low and I picked up additional outs (any 5 or 9 now makes me a straight, to go with my flush draw).
Villian: bets $33.10
Hero: raises $99.30 to $132.40
Villian: raises $48.20 to $180.60 and is all-in
Hero: calls $46.85 and is all-in
Let's look at Villain's decision. The pot was $33 and he got the rest of his stack in, another $180. He had top set, AAA, but there was a low draw on the board and he had no chances for the low half of the pot. If I have a low, he now can't win any more money from me - either I fold and he wins what's in the pot or I'm free-rolling him for the high half of the pot. He has to hope that I'm either folding, or have no low.
The moral of the story: When you have a very good but still beatable hand for one direction (high), but no chances for the other direction (low), then you probably don't want to be shoveling all your money in.
*** RIVER *** [K A 8 6] 
*** SHOW DOWN ***
Villian: shows [K As 7 A] (HI: three of a kind, Aces)
Hero: shows [7 4 T 2] (HI: a straight, Six to Ten; LO: 8,6,4,2,A)
Hero collected $195.15 from pot
Hero was free-rolling - I hit one of 13 outs of 40 unseen cards to scoop, but the other 27 cards would have had us split the pot.
