A difficult decision

8/6/2010 – The fact that even simple looking rook endings can be very tricky is exemplified in this example from the Bundesliga.

Which continuation do you think still offers Black drawing chances here: 53...Rc4, to support the advance of the passed pawn, or 53...Ra8, to harass the white king with checks?
