Pre Flop: (pot: 1.5 BB) Hero has Ah Jh
fold, fold, fold, Hero raises to 2.42 BB, SB calls 1.92 BB, BB calls 1.42 BB

Flop : (7.26 BB, 3 players) Tc Ad 7h
SB checks, BB checks, Hero bets 2.5 BB, SB calls 2.5 BB, fold

A high board decided to bet only 1/3 pot although it is multi way pot and thus more likely that some has something. SB (agro fish only 26 hands though) calls

Turn : (12.26 BB, 2 players) 9c
SB checks, Hero checks

River : (12.26 BB, 2 players) Ts
SB checks, Hero bets 4.5 BB, SB calls 4.5 BB

As SB checks to me and I think hes an agro fish it most likely that I have him beat. I underplayed my A and reasonable kicker and certainly in the eyes of an agro fish. So I put in a small callable bet by a worse A and as I expected the fish calls but that he just has a small pair is something I did not expect :)

Hero shows Ah Jh (Two Pair, Aces and Tens)
(Pre 61%, Flop 78%, Turn 68%)

SB mucks 7c 6c (Two Pair, Tens and Sevens)
(Pre 39%, Flop 22%, Turn 32%)

Hero wins 20.2 BB
Rake paid 1.06 BB

What do you think of the line taken?
Would you bet bigger on the flop and would you check turn and how big would you value bet the river?
