In this position black can delay checkmate for 205 moves with the rook, by continuously sacrificing itself with check, until white gets to a position where he can avoid checks or capture the rook without stalemate. Now the piece count is far from being illegal here, but I wonder if an illegal amount of white pieces could be added in such a way that it extends the puzzle to 300, 500, or even 1,000+ moves! This is the type of "illegal position puzzles" I am interested in here. How complex could puzzles and studies get allowing more pieces?
This one (post#10) I posted early on is the best example of what I am trying to get at with this thread. That puzzle was one of those "too difficult mates for computer programs" puzzles. Black can delay checkmate for over 200 moves with stalemate threats if white takes the rook too soon. The number of pieces in the position is currently legal. But if an illegal number of pieces was allowed, how much longer could the checkmate be extended by adding more white pieces? The same way there are 500+ move forced mates in tablebases, are there even longer ones stemming from illegal positions? That's what interests me here.
No puzzle here, just a simple illegal position. Somehow the six white cdefgh pawns turned into seven pawns.
