58 Scholar’s Mate 144 Scholar’s Mate 144 59 HOW T O READ A CHESS GAME * SOLUTIONS * It's easy. The board has 8 files SOLUTIONS 8 rhb1kgn4 and 8 ranks. Files are the rows MATES TRIPLE LOYD of squares that go up and down. 7 0p0pdp0p MATES TRIPLE LOYD 1 1.Qe8# Each one is named by a small 6 wdwdwdwd A. Kf4# letter. Ranks are rows that go 2 1.Bh6 Bxh6 2.Qh8# 5 dwdw0wdw B. Kh4= sideways. Each one is named 1...f5 2.Qxg7# by a number. 4 wdwdPdwd C. Ka8 (Ra5#) 1...others 2.Qh8# Every square also has a name. 3 dwdwdwdw The first part is its file and the 3 1.Nf5+ Kg8 2.Nh6# 2 P)P)w)P) second part is its rank. In this 4 1.Qd4+ Kg6 2.Qg4# diagram, a white pawn moved 1 $NGQIBHR to e4 and a black pawn to e5. 1...f6 2.Qxf6# abcdefgh When moves are written down, 5 1.Nf6+ Kh8 2.Rxh7# the first capital letter shows the Here are some special symbols: 1...Kf8 2.e6 any 3.Rf7# piece which moves. Q is queen. + check B is bishop. R is rook. N is used # checkmate COMBO MOMBO for knight because the king is K. 1 1.Rd7 Qc4 (1...Qc6 2.Qxf7+ Kh8 3.Qxg7#) 2.Rxb7 If there is no capital letter, that e. p. en passant means a pawn moves. O - O castles kingside 2 1...Qg5 2.g3 (2.Qe3 Qxg2#) 2...Nh3+ 3.Kg2 Qxd2 Next is the square that the O - O - O castles queenside CHESS MAZE piece moves to. Bc4 says that a 1 - 0 white wins CHESS MAZE bishop moves to the square c4. 0 - 1 black wins Rd1-d2-h2-h1-g1-g4-f4-f5-b5-b1-a1-a8-c8-c7xe7 When a piece is captured, an x ½ - ½ draw is put before the square. Qxf7 LILY'S PUZZLER ! excellent move means a queen takes on f7. A. add pawns on c4 a7 If a pawn captures, the letter ? mistake of the file it starts on is given !? cool move 1.a8=Q/R# first, then an x followed by the ?! weird (weak) move B. add pawns on b2 e7 square it takes on. exd5 says a 1.e8=Q/B# pawn on the e-file captures on The game below is written in the square d5. algebraic notation. Kiril was TACTICS 102 When two pieces of the same new to chess and fell into an 1 1.Bxf7+ Kxf7 2.Ne5+ Ke6 kind can go to the same spot, old trap called Scholar’s Mate! another letter is put after the 3.Nxg4 ROCKY KIRIL piece to show what file it came 2 1.Qg3 Rc8 2.Bxh6 from. Rae1 tells us that a rook 1. e4 e5 1...Kh7 2.Bxc7 on the a-file moves to e1. 2. Qh5 d6 3 1.Nxe4 Qxd2 2.Nxd2 If the pieces that can move to 3. Bc4 Nf6 ? the same spot are on the same 4. Qxf7 # (1...Nxe4? 2.Qxa5) file, then their rank number is 4 1.Nxe5 fxe5 2.Qxg4 added. N6e4 means the knight Oh no! Kiril got mated in just 1...Bxd1 2.Nf7+ Kg8 3.Nxd6 on the 6th rank moves to e4. four moves. That was no fun!
