  notyetagm: Petrosian vs Uhlmann, 1968

Position after 35 Rd4xd6!:

35 Rd4xd6! is a lovely tactical shot by Petrosian.

The point is that the sequence 35 ... Qc5xRd6 36 Rd1xQd6 Rd8xRd6

<FORCES> Black to have two <UNDEFENDED> pieces (a3-knight, d6-rook) that are also <LINED UP> with each other, allowing White to win material with the simple <QUEEN FORK> 37 Qf2-c5.

So, in this line, White plays <FORCING MOVES> (captures) that <FORCE> his opponent to have <UNDEFENDED> piece and <FORCE> his opponent to <LINE UP> his pieces.

Your opponent is not simply going to create these tactical liabilities of his own volition (unless he blunders); rather, you must <FORCE> your opponent to make <UNDEFENDED> pieces and <LINE UP> his pieces by using <FORCING MOVES>, just like Petrosian does here.
