Activity in the Endgame

I teach my students three easy steps to evaluate and play endgames.
1) Activity of pieces.
2) Activity of kings.
3) Pawn structure.
Pieces are priority as they have the power and can compensate for material deficit.
Have a look now how Vladimir Kramnik (not my student;) used the force to save himself in his round three encounter against the Italian GM Daniele Vocaturo in Doha:

1. e4 e5 {It seems as Kramnik had given up the Pirc for good. Against the
talanted and sharp Vocaturo he wants to play it save.} 2. Nf3 Nc6 3. Bc4 {

the game, but Kramnik is not afraid of the d3-d4 advance.} 8. Nbd2 {Black has
no problems at all after} (8. d4 Ba7 9. dxe5 Nxe5 10. Nxe5 dxe5 11. Qxd8+ Kxd8

too.} ({Roughly two months ago Ivanchuk preferred to swap the bishops off on
b3, but got nothing out of the opening after} 10. Nf1 Bxb3 11. Qxb3 Re8 12. Be3

novelty which does not change the evaluation of the position-it is equal. The
predecessor saw a quick draw after} ({Predecessor:} 12. a4 Qd7 13. Nb3 Rf7 14.

Nc6-e7-g6-f4 and attack along the half-open"f" file. If White is not careful,
he may easily get into big trouble. Fortunately, A. Karpov is here to help.
The former world champion demonstrated the optimal set-up on the kingside
which every "Italian" player knows.} 13. a4 Ne7 {[%cal Ge7g6,Gg6f4,Yf6h5,Yh5f4]

The king steps away to free the g1 square for the knight. Then once that it
goes back White can repel the active black knights with f2-f3 and g2-g3. This
is what Anatoly Yevgyenievich did against Artur Jussupow in 1986.} b5 {Kramnik
plays all over the board.} (18... Nf4 19. Ng1) 19. Qc2 Nf4 20. axb5 {White
opens the file only to abandon it.} (20. c4 $5 {makes more sense to me.}) 20...

player enjoys some initiative. Still, the game did not leave the boarders of
equality.} 22. f3 ({Or} 22. g3 Ng6 23. f3 $11) 22... Qd7 {Keeps the tension
and creates an obvious threat of capturing on e4.} ({Black could have taken
the open file too} 22... Ra8) 23. Nf1 $1 {[%csl Rd5,Ye5][%cal Re4d5,Ge1e5]

the center. Vocaturo threatens to capture on d5.} d4 {This was Kramnik's
general idea. The pawn will separate the b4 trooper form the remaining forces.}

serious advantage thanks to his more active pieces.} Nf8 33. Nc5 Rd1 34. Re7

activation of the rook was mandatory} (34... Ra8 35. Kg2 Ne8 $1 ({Better than}
