Rough Sacs with Queens

About the only thing that went well at the World Open for me was a bunch of Q sacs.  If, for whatever reason, you insist on writing the answers below, use white ink, otherwise I'll delete your post.

This Q sac was from the second round of the World Open.

This one is from the World Open G/7 Championship.  Seeing that black would likely play Rc8 and hitting my N on c3 with two pieces via an x-ray through my Q, I opted to play Rd7.  Here is the position with white to move.  

The World Open has hardly ended, and since I hit this Q sac in an online game, I thought I might share it, too.  I was white, and it is white to move.
