headsup vs unknown fish

Posted 8 years, 6 months ago

Blinds: $1.00/$2.00 (2 Players) BB: $251.20 (Hero)
SB: $184.00

Preflop ($3.00) Hero is BB with 7 Q

Hero raises to $5.00, SB calls $3.00

Flop ($10.00) A 2 7

SB checks, Hero checks

Turn ($10.00) A 2 7 7

SB checks, Hero bets $8.00, SB calls $8.00

River ($26.00) A 2 7 7 8

SB checks, Hero bets $22.00, SB raises to $171.00 and is all in, Hero calls $149.00

No reads about him just that he is a fish and nearly opening every button and calling every time OOP. Do you fold here ?
