Blinds: $0.10/$0.25 (9 Players) BN: $25.00
SB: $41.12
BB: $82.67
UTG: $47.56
UTG+1: $39.48
MP: $14.66
MP+1: $25.00 (Hero)
MP+2: $25.18
CO: $62.62

Preflop ($0.35) Hero is MP+1 with Q K

3 folds, Hero raises to $0.62, 2 folds, BN calls $0.62, SB calls $0.52, BB folds

Flop ($2.11) 5 K Q

SB bets $1.25, Hero raises to $4.75

How big should I raise on this flop? 3/4 pot raise? Pot raise? but why?
