So, I got a nice welcome to 25NL. This is my very first hand...

PokerStars - $0.25 NL (6 max) - Holdem - 6 players
Hand converted by PokerTracker 4

UTG: $25.00
MP: $18.35
CO: $25.00
BTN: $45.56
SB: $25.45
Hero (BB): $25.00

SB posts SB $0.10, Hero posts BB $0.25

Pre Flop: (pot: $0.35) Hero has 9 T

fold, fold, CO raises to $0.62, BTN calls $0.62, fold, Hero calls $0.37

Flop: ($1.96, 3 players) J K 7
Hero checks, CO bets $1.00, fold, Hero calls $1.00

Turn: ($3.96, 2 players) Q
Hero checks, CO bets $2.00, Hero raises to $5.50, CO calls $3.50

River: ($14.96, 2 players) 4
Hero bets $8.00, CO raises to $17.88 and is all-in, Hero calls $9.88 and is all-in

I absolutely hate my turn c/r sizing, it's fucking awful. I don't know what I was thinking, I think I was taken aback by being in a different sized pot/different stacks etc for the first time. I much prefer a c/r to like $6.80 or $7 given how wet this board is and stack sizes.

By the river, I feel like I have the best hand very often but villain shoves on me which I wasn't expecting at all.

Thoughts?
