Can 16 year old guy become grandmaster?

Yes, it's possible for a 16-year-old to become a chess grandmaster if they started at 15, but it would be extremely challenging. Achieving grandmaster status typically requires exceptional talent, rapid improvement, and often years of dedicated practice. While it's rare for someone to reach this level within just one year of starting, it's not impossible with extraordinary skill and dedication. Most grandmasters have been playing chess for many years before achieving the title, but there are always exceptional cases.

To become a chess grandmaster, especially starting at 15 or 16, requires intense dedication and strategic planning. Here are some tips to help a young player on this path:
