Of course, here too Black was intending to exchange the foremost knight, before occupying e4 with the other one. Again, with all four minor pieces on the board, Black suffers some spatial problems; as seen previously, White may follow up with Ne5 and f2 -f3. The drawback is that the knight on b1 will be temporarily inactive (and in other cases, this drawback may just turn out to be too serious!), but here it may even assist the defense.
Having eliminated Black's central knight, White has a huge space advantage and an initiative on the kingside, which proved sufficient compensation for the pawn. White won on move 35.

Black has sacrificed a pawn and set up an initiative on the queenside. How would you react?
The simplest! In the endgame the extra pawn is more important. In general it is useful to exchange pieces when you are material up.
