B(A.Rubinstein): Ke8,Ba4,a7,b6,c5,d5,f6,g7,h7

Cramped Position

In a cramped position, free yourself by exchanging pieces.
Try to improve the position of the piece that is not doing anything useful.

Example from Round 7 of Alekhine Memorial, Moscow, 1971.
W (B. Spassky): Kh1, Qd1, Ra1, Rf1, Be3, Nc3, Nf3, a3, b2, d3, e5, f4, g2, h2
B (M. Tal): Kg8, Qd8, Ra8, Rf8, Bb7, Be7, Nf6, a7, b6, d5, e6, f7, g7, h7
Black to play

Black has a cramped position, so he decides to sacrifice a pawn and exchange pieces.
14. ..... d5-d4!?
15. Nf3xd4 Nf6-d5
16. Be3-g1 Nd5xc3
17. b2xc3 Ra8-c8
18. c3-c4 Rc8-c7!
19. f4-f5 Rc7-d7
Black has freed up his position.
