In this position Rebel century3 blundered and played 66...Rb6 when white
probably forces mate in 48(The main line is losing a tempo by 67.Rf2 Kg4 68.Rf8
Kg5 69.Rf1 when Rebel to mope has to play a move that desroys black's position I
did not learn the position to understand exactly why but I believe the main line
of chess programs)

How much time does your program need to find 66...Rc3 or 66...Rc2 that are
probably enough for a draw(I am not sure and I may be wrong about it)?

How much time does it need with tablebases and how much time does it need
without tablebases?
