"Outside Straight Flush Draw with Two Overcards"
You may have just Queen high at this point, but chances are it will improve. Your twenty-one outs include the King of Diamonds or Eight of Diamonds to make a straight flush, the other seven Diamonds to make a flush, the other three non-diamond Kings to make a straight, the other three non-diamond Eights to make a straight, the remaining three Queens to make a pair, or the remaining three Jacks to make a pair. 2+7+3+3+3+3 = 21 :) . The chance of improving that hand on the turn is 44.681%. Even if it doesn't hit on the turn, on the river it would be 45.652%. Your overall chance on the flop for the turn and river combined is 69.935%! This is one of those rare cases where even if they have a Ten, you'd still have the advantage over them on the flop due to the sheer number of outs you have to improve.
