Clik here to view.Today, Sergey Kasparov, a GM from Belarus (a country in Eastern Europe, former USSR republic) is going to teach us some great chess techniques and strategies. He will give us some of the best tips and show us helpful ideas about positional exchange that you can use while playing chess.
In chess games or matches, we often sacrifice positions in order to attain some great and positive results. Finding ways to attack the king is our main strategy, however, there are other strategies as well. In these series we are going to learn and discuss the concept of positional exchange sacrifice.
Positional exchange sacrifice is basically sacrificing material to get a better position. It can range from a pawn sacrifice to a queen sacrifice and only aims for one solid goal- winning by the use of positional pressure.
Benefits of Sacrificing Material
- It allows you to take advantage of “the initiative”
- It muddies the waters
- Destructs the pawn chain
- Constructs a “fortress”
- Activates Bishops
The first example below demonstrates a positional exchange sacrifice for the sake of domination. More often than not, such trick can’t be considered to provide an exact calculation or result, one should solely rely on intuition.

On his last move 18… Rhb8, the International Master intended to carry out a simple move: Na5-b7, equalizing the position; however, “surgical intervention” puts Black in trouble.
19.Rxd6! Despite the queens being absent, White reaches domination with a rook getting on the 7th rank.
19…Kxd6 20.Rd1+ Ke7 21.Rd7+ Kf8 22.Nxe6+ Kg8 23.Rxg7+ Kh8
24. Rf7 Re8 25.f5, as we all know, knights are strong support-points.
25…Kg8 26.Rd7 Rab8 27.Rxa7 Ra8 with hope of a-file opening. There’s no point in criticizing Black’s moves, there are simply no good continuations.
After 18… Rhb8, Black is doomed. [27... Nb7 28.Bf4]
28.Rg7+ Kh8 29.Rg3 Hinting at terminal Bh6-g7 29…Re7 30.Bd4 Rf7
31.Rh3 Nb7 32.a4 Rg8 33.Kf3 Nd8 34.Nc5
