X-Ray Attack, Surprise Moves, Defensive Combinations, Trapped Man, Zugzwang, Pt. Deux

I've finished circle 1 and am through the X-Ray chapter on circle 2. I hope to be on my last 2 chapters by Friday. So far, I have made my way through 87% of the Reinfeld 1001 WCSC book. It seemed like nearly every one of the problems in the Defensive Combinations chapter was used by GM Blokh (and CT-Art 3.0).
