@Shaddy: Problems 1 and 3 look good. For Problem 2, did you consider if white responds in this way?

Not sure, but it transposes, right?

Problem 3: Two moves jump out at me. I thought both failed, but now I'm unsure about the second. I'll have to review my attempt when I have more time.

Solutions and the next round will be postponed until this weekend. I had some personal business today to attend to. |
