Natarajan MMate in Two Moves - Chess exercise book for chess players - 500 Puzzles with answers

Product is nice and useful for kids who are interested for chess

While you are travelling, if you don't want to play chess puzzles on mobile apps anymore, this kind of book is nice to carry. The author has a series of books like this one (Mate in 1, 2, 3, 4, and also other puzzles with focus on their individuality). It's a nice collection to own. The books are made in an exercise book format. Just carry a pen and one of his books and keep trying.Regarding the puzzles, (I haven't tried them all but an ample amount) the puzzles are not extremely hard. If you are an advanced player you may not need these books but it's a nice series for beginners , maybe even for some intermediates.

By mistake I have found a mate in 4 as per the answers in the first hundred problems. only mate problems as the title says

I like the book very thick and white to mate 250 positions and 250 for black. but 2 to three positions are wrong

Almost ok
