I was having a great day until this happened. Does this qualify as a badbeat, or did I just not bet enough? konstantin2 had been raising every pot he entered, regardless of position, and had been making plays similar to this where he would raise the hand with suited connectors from first position. The possibility of a straight did occur to me when he bet on the turn, but at the time I thought he was betting his draw to see the river cheaply. Should I be kicking myself for not betting more on the flop, or re-raising more pre-flop?
