Great video by Charlize ! I was able to solve the initial puzzle by Sofia Polgar but was not able to do the other puzzles. I was wondering if it makes sense to buy these books in that case.
Thank you! The other books are a bit trickier, but remember that you should spend time solving studies. They are generally not as quick to solve as tactics, particularly the endgame ones. So I would start out with Shahade's book, and move on to the next ones after. Studies can be tough, but they are worth it!
