I'm a bit rusty after a few weeks off over christmas so any comments on any street are appreciated.

HAND 1 - My first orbit at the table. I was trying to pick up the dead money PF really but I'm not sure about my turn line. Maybe bet $7-8 instead or C/R AI?

UTG ($31.65)
MP ($27.85)
Button ($27.30)

BB ($55.50)

Preflop: Hero is SB with K, A.
1 fold, MP calls $0.25, Button calls $0.25, Hero raises to $2, BB calls $1.75, MP folds, Button folds.
