The MPs/mps on the board excepting His Majesty. The value of a player’s chess MPs/mps. The player with an advantage in material, or who is ‘ahead on material’, has a total MP/mp value greater than that of h/her opponent. If a PA is counted as one unit of strength, than QU1 is worth 9 PAs, a RO is worth 5, and BSs and KTs, 3 points each. Do not blunder away material. This mistake is the single most common cause of losing a game of chess. So, before making a move, ask yourself these two key questions: Is :Bposing a threat that I have failed to recognize? In other words, is :B attacking one or more of your MPs/mps and, in doing so, forcing you to take immediate defensive action? Does my intended move allow one of my own MPs/mps to be taken or put en prise? That is, will your MP/mp be taken without compensation - are you planning to place a MP/mp on a cell where it is attacked but not defended, or where it may be captured by a MP/mp less valuable than itself? Has :B’s last move given you the chance to take one or more enemy MPs/mps safely? Taking advantage of your opponent’s mistakes is just as important as avoiding mistakes of your own. The total value of the MPs/mps on the board at any given time during a game.
