Bill: I believe that B7 - W10 is a 3 point sente. At first blush, it looks like a 4 point sente. W7 would gain 2 points for the black+circle stone plus the 2 circle points, but if White has played at W7, Black will connect at a instead of B9 when White saves the white+circle stone. Then White would get the 4th point only by playing the 1 point gote at W10.

(Actually, things are a bit more complicated. It is possible that some lines of play on the right side will affect the circle point on the fourth line, and I calculated the play with that in mind, but I still get B7 to be a 3 point sente.)
