Chess: 5334 Problems, Combinations, and Games

It is live on Facebook and batch is today 7-8

Puzzles 1-700 should take no more than three seconds each. Then the amount of time needed will gradually increase. I’m a little past 1600 and find they now take anywhere from 1-15 minutes to solve.

I am considering buying this book. But I am wondering how important is it to be able to spot these mate in 2 and mate in 3 in a game for becoming better? GM Jesse Kraai seems to be a huge fan, but aren't "normal" puzzles like where you just win a piece more common and useful?

A lot of the positions, as I recall, are a bit contrived and likely not from real games. However, they are useful for calculation practice, as there are a lot of possibile defenses on most (excluding mate in 1), if not all of them, and you have to make sure you see all the mates after the first move for each defense

I got the big hardcover book in the 90's, later bought the smaller (and thankfully lighter paperback) when it was released, and now have the book on Kindle. Having it as an ebook makes so much more sense. The other two versions make excellent doorstops when you are done with them.

I could implement it in my daily workout.

Am working thought the book and have reached the Mate in 2 section.

I do not understand the notation for the answers.

#307.

T.Kardos 1971

1.Kc3

Is this a credit to the puzzle maker and the answer is just Kc3?

Thanks in advance.

Yes.

Tivadar Kardos with István Rágó published the paper Feladványkedvelők Lapja (Paper of the Friends of Chess Problems) from 1969 to 1976. For most mate in two problems, only the first move is given. That's normal for most chess books. Polgar gives the full solution when you get to the mate in three problems.
