Becoming a Master for Adult
If you learn chess after becoming an adult, you still have a chance to become a master. Did you say, pardon me? Oh well! I know its not easy. But with modern technology at our homes, and with the best engines to help us study.. why not?
You only have to give yourself time.. and more time for chess in front of computer and books. I hope your wife will understand, support you with a cup of coffee maybe.
Learn,by heart, do whatever you like, just memorise the moves, lines, variations, dont follow the chess rules of thumb, whatever, your goal is to become a master no matter how.
Try it, and become a master (only for adults)
