Pre Flop: (pot: 1.5 BB) Hero has 8s Qh
fold, fold, fold, Hero raises to 2.5 BB, SB calls 2 BB, fold

Q8o is def the bottom of my opening raise here

Flop : (6 BB, 2 players) 8d 2h 7h
SB checks, Hero bets 2.5 BB, SB calls 2.5 BB

Nice flop for me but there are two hearts on board and a possible straight draw so I bet 1/2 pot for protection and for value

Turn : (11 BB, 2 players) 4d
SB checks, Hero bets 4.5 BB, SB calls 4.5 BB

Don't know if I l like my turn bet here but still there are draws on this board so 1/2 pot bet again

River : (20 BB, 2 players) 3d
SB checks, Hero bets 8.5 BB, SB calls 8.5 BB

Villain showed no aggression and only a straight is a possible draw but that hand would likely have either raised on turn or bet out on river so not much change he has that hand. As I have top pair reasonable kicker I choose to value bet thin as I think I can get called by both worse 8 and something like A7 or 67 or ...

Hero shows 8s Qh (One Pair, Eights)
(Pre 60%, Flop 79%, Turn 80%)

SB mucks 7c 5c (One Pair, Sevens)
(Pre 40%, Flop 21%, Turn 20%)
