 The following position is from Arkell, K. vs. Holland, J. White to move 4r1k1/p1r2pp1/2p5/Q7/3p2Pb/P2NqP1p/1PR1P2P/4RK2 w - - 0 28  GM Arkell saw a tactical way to trade all pieces. He deemed that the resulting pawn ending was winning. From the book Arkells endings: 28.Qxc7 ... And here was my idea. Holland automatically assumed that this capture wasn't possible as his reply appears to win on the spot.  28...Qxd3 Threatening 29...Qxc2, 29...Qe3 and 29...Qxf3+, so it appears I must resign.  29.Qd8 For my trap to work, the Queen must pin Black's Rook, preventing ...Qxf3+; attack the Rook with check to avoid ...Qxc2 followed by ...Bxe1; and threaten the Bishop to eliminate ...Qe3.  29...Rxd8 The best he can do is head for an inferior ending. If 29...Qxc2 30.Qxe8+ Kh7 31.Ra1 Qxb2 32.Rd1 and I'm well on top.  30.exd3 Bxe1 31.Kxe1 Re8+ 32.Re2 Rxe2+ 33.Kxe2 f5 For the exchange Arkell needed to think 11 ply ahead, with all variations. Furthermore, he had t...

 The following concepts emerged: A file is open when your own pawn is missing or hidden Ultimate goal of an open file is the penetration of the 7th or 8th rank There is no difference between play against a piece and against a point Attack the defenders of the entrance point A file is opened when the opponent trades a piece that is defended by a pwan Provoke such caption by placing your pieces in the center The file next to the exchanged piece will be opened Obstacles on the open file can be removed by piling up (evolutionary) Or by a sacrifice (revolutionary) An open file can be used as a rooklift A knight as outpost undermines the pawn that it is blocking by attacking its defending pawn An outpost must be supported by a pawn An knight as outpost provokes the defending pawn to step forward The power of an outpost is derived from the open file and the pieces and pawn behind it When an outpost is exchanged, and you take back with a pawn, the enemy pawn is blockaded. At the same time ...

 I found the following concepts. Or "rules" if you like. In the opening speedy development is paramount A pawn move is not a development move Only pawn moves that occupy or support the center are allowed in the opening Don't move the flank pawns in the opening, unless it is a closed position where development is slower Maximum two pawn moves in the opening Win tempo's by threatening enemy pieces Develop with one move per piece When your opponent does a non development move, you can do likewise without getting behind in development Don't trade pieces in which you have invested much tempo's Liquidate the center when your development is impeded Method 1: exchange with gain of tempo Method 2: liquidate the center followed by a development move or a freeing move Mobile center pawns are criminals that should be eliminated or put under severe restraint.
