Every week we present you an endgame study – this week not selected by IM Yochanan Afek but by another, quite famous player from Israel. Last week, at the Kings' Tournament in Bazna, Boris Gelfand showed an ending to Magnus Carlsen, and he was happy to show it to our readers too. Good luck solving! Update: improved version after Mr. Gelfand emailed us.

At first we gave the position below, which actually happened in the game, and in which there's only one winning move. But in fact a slightly altered position makes a much nicer study, as Boris Gelfand noted in an email to us. First the 'wrong' study, which you might try to solve as well:

From the game Gelfand-Wang Yue
Russian Team Ch 2010

White to play and win

And now here's the position Gelfand showed to Carlsen last week:

Inspired by Gelfand-Wang Yue
Russian Team Ch 2010

White to play and win

Try solving without checking the tablebase! Next week the solution.
