Even the best are human are human - evidence?

Thanks Tony ... one to you, though that one is also in Wikipedia under 'Chess Blunders'.
Tim Krabbe also has a set of cases where one player resigned rather than play the winning move - incredible but true.
Third source is the '??' in GK's 'My Predecessors' - though these are not always drop-dead-obvious [to me] blunders.

Hi Guy.

I got this particular position from a book titled Blunders And Brilliancies, by Ian Mullen and Moe Moss. It's basically a tactics exercise book, but the positions in the book are tactical oversights and premature resignations from real games.

How about this position from the game Emma-Stein, Mar del Plata 1966

[D] 8/pb3pbk/1p4pp/2p5/P1P2P2/1nP1Q1P1/7q/2BRNK2 b - - 0 1

Stein thought for 20 minutes, then decided to put his queen en prise with ...Qc2??

Emma replied very quickly, with Rd7??

A strange double oversight
