It's been a couple of weeks since I left the difficult forks, so let's look at them now!
Seeing a fork is easy, but making them happen can be tricky. The puzzles from 2 weeks ago included 2 from World Championship matches! That was the quality of the players!
Anyway, did you manage to make the forks happen? Here's the answers. If you didn't work them out fully, then don't worry. Trying to solve puzzles helps us to understand the idea better in the future. Getting something wrong isn't a failure as long as we learn how to get it right for next time!
