Queening Combos, Vulnerable First Rank, Queen Sacs

My latest themes. I'm finding these, so far, to be much easier than the dreaded Clearance and Interference themes I just completed. I'll be 75% of the way through Reinfeld's book after I complete these themes, and I'll divide the rest of the book into two groupings before I begin consolidating. By consolidating, I mean dividing the whole book into larger and larger groupings for working my 7 circles. It's looking now like I'll probably finish everything by the end of June and will join Don in the ranks of the graduates De La Maza.
