Here is a hand I played particularly poorly.

$.25/$.50 NL
I have $24.50, my opponent has me covered.

One early position limper, I limp from middle position with :Ac::Td:, the SB completes, and the BB checks.

Pot: $2.

Flop: :Ah:

SB bets $2. BB folds, early position limper folds. I raise to $6.

SB reraises to $10. I call.

Pot: $22.

Turn:

SB checks, I check.

River: :Tc:

SB bets $6, I raise all-in for $14, SB calls.

Final Pot: $50.

(I'm not looking for a critique here, I know I played it horribly. This is a problem for you guys.)

What does my opponent have?
