(++) 2 games, 2008 1ST & 2ND RANK TRICK: APPLIED LVPOC (OVERLOADED) 5 games, 1946-2012 3 Piece Rule You need three pieces to checkmate the enemy king, one to sacrifice and two to deliver mate. Of course more is better. :-) 6 games, 1950-2009 4 pieces in a row: clearance for discovery _THREE_ pieces in a row make a discovery chain. So if there are _FOUR_ pieces in a row, we need to move one of our pieces out of the way with a <GAIN OF TIME (CLEARANCE)> so that we will have the requisite _THREE_ pieces in a row for the <DISCOVERED ATTACK>. 3 games, 2007-2010 7th heaven! 7th rank above all!

Your pieces are -NOT- safe if they are in <ALIGNMENTS/CONFIGURATIONS>: files, diagonals, ranks, pawn forks, knight forks, king forks. Your pieces are <LINED UP>, that is, your pieces are in an <ALIGNMENT>, if an enemy piece can exploit the <SQUARES> on which those pieces reside. And then it's a simple matter of <ACTS - ALIGNMENTS CREATE THREATENED SQUARES>. In the Greenfeld-Daly Irish Ch. (9) 2008 game, the White c2-rook and White f3-queen -ARE- <LINED UP> via the e4-square because the light-squared Black b7-bishop on that e4-square can exploit the fact that the White rook and queen are on the c2- and f3-squares, respectively. And in Adams-Bareev Corus 2004, the Black c8-rook and Black g8-king are <LINED UP/MAKE AN ALIGNMENT> because a White bishop on the e6-square can attack both of those Black pieces on the squares on which they reside (c8 and g8) (♖e1xe6! 1-0 <reload>). Of these <ALIGNMENTS/CONFIGURATIONS> the most dangerous is the <KNIGHT FORK ALIGNMENT> when an enemy knight is located nearby or is centralized. See the games Topalov vs Nisipeanu, 2007 (White d3-queen + White g2-king with Black d5-,e6-knights) and A Aleksandrov vs Adams, 2002 (White h3-queen + h1-king with Black g4-knight) for examples of this particular <ALIGNMENT/CONFIGURATION>. 53 games, 1909-2017 Advance flank pawns when center is closed/fixed 2 games, 1992-2008
