Comments on all streets appreciated, please just say why.
Villian runs at 28/6 over 200 hands, probably about a breakeven player.

I am dealt A[s]9[s] in the CO. Folds to me and I raise to $4, SB calls.

1. Pot $9, Flop A[c] 4[c] 2[h]. SB checks I check.

2. Pot $9, Turn comes 9[h]. SB leads $9, I raise to $25, SB calls.

3. Pot $58, River comes 3[h]. SB open pushes all in for $62.

Errrrrrrr?
