Even I am fallible

For the record, I misplayed a hand post-flop yesterday.

I am SB with AQ of spades, the flop is A J 3 rainbow with one spade. I bet and button calls.

The turn is a 6 of spades. I bet half pot and the button raises to 4 times my bet. I call.

The river is a brick, I check, button bets and I fold.
