MissScarlett: I should point out that on both page 21 and page 23, all of Pollock's seven opponents are named (from which he scored 6.5, winning the event) and Hvistendahl wasn't one of them, so the error must be one of those schizophrenic mix-ups where co-authors are involved.The game first appeared in the <Morning Post> of October 5th 1885 with the description: <The following game was played recently between Mr. W. H. K. Pollock and an accomplished amateur...>
The opponent is <Mr. A.> and the game is the 33-move version given here.
The second sighting was the <Hereford Times> of March 4th 1899, p.3, in which it is noted: <We are indebted to Mr H. E. Bird for the following remarkable game played by the late Mr W. H. K. Pollock at Simpson's, on October 1st 1885. Mr. Bird is of the opinion that the game has not hitherto been published.>
Brief notes, said to be by Pollock, are given and White is identified as <Mo...>
Finally, the game features in the book <Pollock Memories> by F. F. Rowland which appeared toward the end of 1899 as game #16 , p.31, <Played at Simpson's Divan, October 1885.> White is <Mr. Kvistendahl>. Different, more extensive notes by Pollock are given.
Both the <HT> and <PM> have the game ending with <32...Rxd2+>.
