IIRC, I think AOC also commented once he did not feel challenged by the book. I think it likely many might agree. I found a very abrupt change in difficulty came at problem #1471 and onwards. Not that it is horrifically hard: just a progression to a different solving method. It becomes less about check and/or sac/then mate, and more about black's king is all but trapped but any move by white frees him. How best to first release, then reform the mating net? (That is my way of putting it anyway). A lot of fun. So I think the book is progressive and repetitive of patterns and that this was one way to drill his daughters. I only do 6 a day after breakfast since I began the mate-in-two chunk. It should take about 2 1/2 years to do the whole 5334. But I don't mind as I study other chess subjects as well; it's a part of the package. Why rush? I also do 10 free puzzles on Lichess in bed each night and those are much easier.

Thanks!

@ Kerangali,

Um, that was not the answer I was looking for. Are you saying that the 5334 book *was* the list of training positions Polgar used for his daughters? Or that those particular training positions are *included* within the book? If so, which ones? If those positions were published, but not published in the 5334 book, do you know where? My initial post was not this specific, so my bad if I was not clear.

TIA

Yes - I pm'd Tony about batista, but he has not responded yet. And I can't ban him.

Can you give an exact url for this website or tool? I see nothing of the kind.

I think Lazlo Polgar (the father) used a similar method for training his 3 daughters, with tremendous results. He published his training positions. They were not on the verge of difficult but rather exemplary and well thought-of (= memorable). Perhaps this is best for pattern recognition, which is the base of chess tactics ability.
