Good puzzle. Not to obvious for me.
Mate in two (standardized)

This one took me longer than the other one. Don't be discouraged if they seem trivial, again, somebody who uses logic rather than sheer calculation can solve most #2s with few pieces easily. After all, the check on the White King removes most possibilities. You're doing much better than I do with these.
I believe this construction is more efficient if there's only one solution; however, I don't have time to engine-check it.
White to play and mate in two moves. This problem is compliant with SirDavid's and NM tonydal's suggestions regarding removal of extra pieces. However, I have a feeling I made it too trivial...
