a man said Rc7+ but why is my move wrong ?
First one to solve this puzzle gets 10 points

Here's how it works: @WolfKid18 and @shauryachirimarmh will negotiate a day when they are both available. I will post puzzles in the morning and in the afternoon. Person who scores the most points during that day wins week two.

We will start in a few minutes. Please make sure you are online now and vigilant at all times. You never know when a puzzle is going to pop up.
