: Ok why can't I capture the '3' above the one you just played?

I'm trying to understand your question, so that I can help you understand the rules/UI. At this point, the most recent move by spartacu5 is a "3" on G6, and based on when you posted the question, I believe that is the one you calling "the one you just played", but I don't see the "3 above" that one that you are referring to in your question. (I see your "2" as the stone directly above that one).

Can you give the coordinates for the stone you are trying to capture? (Note that column "A" is the left side and that the "1" in any column denotes the cell nearest the bottom.)
