Preflop: Hero is SB with 7♥, 7♠
2 folds, BU raises, Hero 3-bets, BB folds, BU caps, Hero calls.

Flop: (9,00 SB) A♥, 6♦, 2♠ (2 players)
Hero checks, BU bets, Hero calls.

Turn: (5,50 BB) 5♦ (2 players)
Hero checks, BU bets, Hero calls.

River: (7,50 BB) Q♣ (2 players)
Hero checks, BU bets, Hero calls.

Final Pot: 9,50 BB

Is this standard against a LAG like BU?
Or is this an easy fold after the preflop cap and the A on the flop?

I bet that the 2nd is true.
