At matchpoints, not vulnerable vs. vulnerable, I opened one heart with the following (all X's are 7 or lower).
♠ J9x
♡ A9xxxx
♢ J9
♣ AT
Normally, I need 11, not 10, high card points to open even with a good six card suit. Here I "stretched" with 10 because of the two doubletons and good intermediates (three 9s and a T).
Partner raised to game with 12 points (opening hand), we went down one, losing one trick in each suit, and got a bottom on the board.
Was this an unlucky result? Or did I overbid?
