NO

White can simply ignore the rook . He don't have to take on the rook.

hehe very nice, i got this one my first go and dc1985, how can black win? blacks pieces are all blocked by his own pawns

I stand corrected... My bad!

EDIT: Lord-Chaos, that was if- and only if- White chose to take the offered Rook.

this is retarted... no game would ever get to this point if either of the players had any idea at what they were doing

 well, not a lot of puzzles are realistic.

and would you take a look at Sam Loyd's puzzles, How many of them are realistic(what is unrealistic? bad promotions, a knight in a corner, white/ black has an enormous material advantage, etc.)
