BB is 17/8 over 50 hands, I'm running the bog standard 20/17 and haven't been out of line. SB is 40/20

Seat 1: BB ($24.60 in chips)
Seat 3: UTG ($27.05 in chips)
Seat 4: MP ($26.45 in chips)
Seat 5: Hero ($27.45 in chips)
Seat 9: SB ($24.55 in chips)
ANTES/BLINDS
SB posts blind ($0.15), BB posts blind ($0.25).

PRE-FLOP
UTG folds, MP calls $0.25, Hero bets $1.25, SB calls $1.10, BB bets $6, MP folds, Hero reckons cheeky nit is full of shit

This is textbook squeeze and the only reason I didn't shove was because of SB.
