Mueller on Endgames: Moscow mastery

by Karsten Müller
2/5/2015 – An opponent is most dangerous when his back is to the wall, and this is especially true in chess. In the first position, 13-year-old Iranian prodigy shows his alertness as he brings home the point. The obvious move can be wrong, but would you have seen it? How about the adage that states a rook belongs behind the pawn? So true, yet here it takes on a rather spectacular form.

Avoiding the trap

Despite being only thirteen years old, Iranian M. Amin Tabatabaei showed
his knowledge and alertness as he avoided a final trap the more experienced
Aleksey Goganov had hoped would save him. Study the position and choose
your answer before replaying the analysis. Black to play and win.

The mating net

It is sometimes easy to forget that direct attacks also occur in the endgame. Hungarian junior
Petra Papp (left), playing White, reminded her opponent of this in the following position.

The hunt

Take a minute to absorb the position. Black has a pawn ready to queen, and two
other pawns as backup. You are white and have a rook and two passed pawns,
including one on h5. Black just played Ne5 check. What do you play as White?

[Event "Moscow Open A 2015"] [Site "Moscow RUS"] [Date "2015.02.02"] [Round "3.6"] [White "Tabatabaei, M."] [Black "Petrosian, TL."] [Result "1/2-1/2"] [ECO "B08"] [WhiteElo "2444"] [BlackElo "2663"] [Annotator "Karsten Müller"] [SetUp "1"] [FEN "8/2p1p3/6K1/4n2P/8/3k2P1/1p6/5R2 w - - 0 50"] [PlyCount "19"] [EventDate "2015.01.31"] [EventType "swiss"] [EventRounds "9"] [EventCountry "RUS"] 50.

The rook belongs behind the passed pawn

Another day, another lesson. Black realised a non standard version of this guideline in the game.

If I have a winning advantage against her I will not mate her immediately. I will drag the game to the last second of the time control.
