Illegal EPD?

[jordanbray]

Simple question. The following EPD looks illegal to me. However, it seems that it has been used for lots of chess engine testing. It appears to me that the queenside castle for black is illegal.

2r1k2r/2pn1pp1/1p3n1p/p3PP2/4q2B/P1P5/2Q1N1PP/R4RK1 w q - bm exf6; id "LCTII. CMB.06"; c0 "Lilienthal - Capablanca, Hastings 1934";

Am I missing something stupid?

Thanks.

Here is the FEN from the actual game:

The black rook of the queenside is not placed on a8, so the long castling is not possible. I have just searched the game on ChessGames.com and went up to the previous move of exf6. Then I clicked on b8 square to obtain the FEN of the position, and it ends with k - 0 20. It looks like a typo. Thanks for the report.

My answer is basically a duplicate of Louis' answer but specifying the source of ChessGames.

Hi, Jordan.
Perhaps you do not put the correct position, and it is another position.

Cool. Thanks. I just needed to check here to make sure I wasn't going insane.
