A look at mistakes in chess problems, stamps and book covers.
Then a look at the worst mistake of all and an RHP example.

Well done again. Thank you.

Thanks, though I am very slightly annoyed.
If only I had delayed posting the blog for one day.

I mention the Sandor - Herendi, Budapest, 1948 game in the blog.
(it is the position where Black resigned in a won position)
The position appears in various columns and books. The first sighting
is in a Hungarian Book from1959. We are looking for earlier sightings
and hopefully the full score.

Ian Rogers, the author of OOPS! pictured in the blog is amongst those looking for the
full score. During our emails (a day after I posted the blog) Ian pointed me to this position.



It appeared in the book 'Psychological Guide to Chess' by Jirí Veselý
claiming White resigned in a won position.
(White did resign but it was a correct decision, the position is lost.)

The author thought 1.Qc4 saved the game only looking at 1....Qxh2+
but 1....Qh3 wins for Black.
This would have made an excellent add on in the blog of mistakes.
