Problem No. 187.
White to play and mate in two moves.
FEN 8/4p3/K2p4/1P5r/3k1N2/Q2B2R1/1R6/6b1 w - - 0 1
Solution: 1. Qa1 Be3 2. Rc2#

LINE CLEARANCE
There will be times when you have some kind of threat of a rank, file, or diagonal, but the threat cannot be carried out, due to the fact that you or your opponent, or both of you have other men on the same line, making communications impossible. Line clearance is a means of removing all pieces off the line that have nothing to do with the threat.
It is simple to remove your own men off the important line, but it takes skill and foresight to remove the enemy. The only way to get enemy men off the line is by forcing or forceful moves. Once you accomplish this, then your threat is ready to be sprung.

Advantages
The advantages of a line clearance are great for winning material, since moves that have nothing to do with the threat, often produce smaller threats and if not answered correctly, will give you a winning advantage. Here is sample from a game played in Pittsburgh recently.

Algebraic

(a) White played to win the queen in, what looked like, simple fashion. With an open board there is still no safe retreat for his own queen. If 13. Q-K3 N-B7ch, etc. and Black comes out of the melee a piece up.
