Skilled players need no more thought to play this position correctly than to speak the basic phonemes in their native language. That's the contention of Rashid Ziyatdinov, whose book I discussed last February in "GM-RAM: Essential Knowledge."
The position arose in Malakhov-Najer, Moscow 2007 and came to my attention via the CD Chess Informant 5-99 Endings Section. Endgames have been part of every issue of Chess Informant since issue 5 in the late 1960s. Most problems are more difficult than this one.
