After several years of trying to buy this pamphlet, I finally got a
copy on e-bay for 30 bucks. It is a hard book to find, and Kolty's
chess problems are not represented anywhere in the chess problem
literature as near as I can tell (they aren't in the databases) and
that is a deficit , as it shows further evidence of his all-round
skill. It was published by the San Francisco Chronicle, but no date
is given.

I am currently transcribing the problems to be places in one of the
many on-line chess problem databases, and making corrections of cooked
problems, but the lack of dates for the problems or book means the
date entered will be 0000(?), meaning publication date not known, not
a good thing for the problem.

Does anyone have any more information on the book or is there perhaps
a compilation of Kolty's columns somewhere where I could find dates
for these?

Anyone with any information on Kolty and his problems (I think there
are more that were published in Chess Life), please contact me. I
might also make a pdf of my results available on the web so that
chessplayers might see them (Kolty's problems tend to be spectacular,
as one would expect from a master showman, the kind that "chessplayers
who like to solve the occasional problem" find intriguing), so I think
there may be general interest in them.

Of the ones I have set, this is the one I have found the most
interesting and spectacular:

Problem No. 4

FEN: 8/4p1KQ/2p5/R2pk1N1/7R/2N4B/b6p/B4r1q w - - 0 1
