New to NL, Did I need a Killer Instinct for This Hand?

[The Duff Man]

First post....help me out with any recommendations for this NL hand. The results were
positive but I need to learn how to do better. Table was fairly tight,
I had only played about 20 hands but I didn't see any raises of All-in.

Seat 5 is the button
Total number of players : 10
Seat 1: iamshows ( $21.75)
Seat 2: The_Duff_Man ( $29.50)
Seat 3: duckey123 ( $24.50)
Seat 4: BRIANSLADER ( $45.50)
Seat 5: Itsonlyasix ( $23.25)
Seat 6: ANGFILIPPONE ( $25)
Seat 7: snappoker ( $8.30)
Seat 8: Out
Seat 9: dowman ( $23)
Seat 10: tizza ( $44.35)

snappoker posts small blind (0.25)
dowman posts big blind (0.50)

Dealt to The_Duff_Man [ Jd, Jc ]
tizza calls (0.50)
The_Duff_Man raises (2) to 2
snappoker calls (1.75)
tizza calls (1.50)
Preflop - I was thinking I wanted one or two callers. Should I bet more because my
hand is so vulnerable, trying to knock out everyone and get just the blinds and the
one caller?

Flop [ 2s, Js, 2c ]
snappoker checks.
tizza bets (4)
The_Duff_Man calls (4)
snappoker folds.
Flop - Pretty much a perfect flop, and he is betting into me. If I raise I am
guessing I will knock him out because buy in was $25 and he has $44, so he has either been
playing well or getting lucky. By limping maybe I can get him to raise all the way to
the river.

Turn [ As ]
tizza bets (2)
The_Duff_Man calls (2)
Turn - The same scenario as above. I am not concerned he has AA since he didn't raise
preflop.


River [ Qd ]
tizza bets (2)
The_Duff_Man raises (10) to 10
tizza calls (8)
River - Based on the size of his bets I don't think he hit a hand that will beat me.
I want to make sure he calls my bet. Am I wrong for not throwing my whole stack in, or
is that what most winning players would do? $10 was about half of my remaining stack.


Board: [ 2s Js 2c As Qd ]
The_Duff_Man [ Jd Jc ]
tizza [ Jh Qh ]
He hit two pair, but even if I was holding AA or KK I would have him beat because of
the 2s on the board. Hard to guess if he'd have called an all-in bet by me, he hit his
hand but he might have figured me as slow-playing. What do you think? The result was
still positive, but am I better off throw all-in and go for the throat?
