BB ($20)
MP($25.00) -->hero
Button ($30.65)


Preflop: Hero is MP with AA. SB posts a blind of $0.10.
2 folds, Hero raises to $1, 4 folds, Button calls $1, SB folds, BB calls $1.

Flop: ($3.15) 2, T, K rainbow (3 players)
BB checks, Hero bets $2.5, Button folds, BB calls $2.5.

Turn: ($8.15) K (2 players)
BB checks, Hero checks.

River: ($8.15) 3 (no flush/straight possible)
BB bet $0.5, Hero raises to $3, BB Pushes, Hero ????

I was confused by BB's mini-bet on the river, and thought it was a blocking bet. after BB pushes, it seems he had a K. fold??? is turn check ok?
