The Great Pawn Hunter
Chess Tutorial

It was a new year at the Great Pawn Hunter's school. Some of the students were to be selected for a special class for learning computers. Alas, Shrubs didn't have the grades like his other friends did. Even the Talker had made the chosen list for he was a naturally gifted scoundrel. It was a shame he used most of his talents for deeds that were, how shall I put it, "Against the grain."...

Well, the Great Pawn Hunter and the Restless Knight went off to their computer class, along with our villain, where they learned how to use the computer for mathematics. This was not Shrub's strength and that was why he wasn't chosen. When the bell rang to end school for the day, the Great Pawn Hunter and the Restless Knight found Shrubs, at Castle French Fry, playing chess with Old Maestro. Shrubs was depressed at first. But, Old Maestro worked his magic and brought Shrubs out of the dumps. You see, they were playing for fries. A rook was worth five fries, a Knight was worth three fries, a Bishop was worth three fries, a Queen was worth nine fries, and a pawn was worth 1 fry. Now as Shrubs was winning game after game with quick checkmates, Old Maestro was capturing pawns and pieces and taking all the fries. Shrubs didn't know it, but, Old Maestro had checkmate worked out in his mind many times. However, he wanted Shrubs to taste victory and Old Maestro wanted to taste the fries for he was very hungry...the poor old soul. Now Shrubs felt like a million dollars. He must have won five or six games in a row. "Old Maestro," said Shrubs "I don't understand. You are a much better player than me. Are you trying to make me feel better by losing?" Old Maestro turned red in the face. His good deed was shown in the light. "Who me?" said Old Maestro "I tell you what. I'll play you for a root beer".

Now, later on in the day, the Great Pawn Hunter and the Restless Knight joined the group. "How was computer class?" asked Shrubs. "Well," said the Great Pawn Hunter "Sarge is teaching and it feels like detention." Shrubs smiled "Been there, done that." said he. "I wish we could do something else with computers" said the Restless Knight. Now, by this time, Old Maestro was sipping his root beer and making another move on the chessboard. He saw what the others were doing for Shrubs. Old Maestro remarked "You chess players are natural for computers, You too Shrubs." "But why," said Shrubs "I'm terrible at math. To me, one and one is eleven!" Old Maestro smiled and said "Computers are run by logic and you are naturally gifted with this." "What do you mean?" asked Shrubs. Old Maestro asked Shrubs a question "When you play chess, and you are about to make a move, what are your thoughts?" Shrubs replied "Well, I say to myself 'If I do this then my opponent will do that'." "Ahh," said Old Maestro "That basic 'if/then' statement is at the heart of all computers. It is the logic that drives them. Shrubs replied "Do you mean to say that I can put my thoughts into the computer and make it think?" "Yes," said Old Maestro "You don't have to be a mathematician. Even the Talker can teach a computer how to think." "Now, there's a scary thought." said the Great Pawn Hunter. "The computer," said Old Maestro "is just like a new born baby. It knows only what you teach it."

Now, Old Maestro finished making his move on the chessboard. But, this time Old Maestro had to play honestly. He sacrificed a piece and forced the win. "Wow," said Shrubs "You're good." "You played great chess today" said Old Maestro. "Thanks," said Shrubs "How's your soda?" Old Maestro smiled and said "Next time we'll play for chicken nuggets." The following game is Old Maestro's forced win. Old Maestro played the white pieces and Shrubs played the black pieces:











1.d4 Nf6 2.c4 e6 3.Nf3 b6 Queen's Indian Defense
4.g3
Main Line 4...Ba6 5.b3 Bb4+ 6.Bd2 Be7 7.Bg2 c6 8.0-0 d5 9.Qc2 0-0 10.Rd1 Nbd7 11.Bf4 Rc8 Both rooks have posted themselves on files against the opposing queens. If only they could open the rook's files.
12.Nc3 Nh5 13.Bc1 Nhf6 14.Bb2 dxc4
Shrubs decides to win a pawn.
15.bxc4 Bxc4 16.Ne5 Nxe5 17.dxe5 Nd5 18.Ne4
Bringing the knight to e4 behind the e5 pawn is a common plan to occupy the pawn's outposts either on d6 or f6.
18...b5 19.Nd6 Bxd6 20.exd6 Qd7
The queen can not take the pawn because of e4 winning the knight, since the knight would be pinned to the queen. [20...Qxd6 21.e4 Nb4 22.Qc3! ]
21.Rd4 f5 22.e4 Nb4 23.Qc3 c5 24.Rd2
Old Maestro's queen and bishop attack down the a1-h8 diagonal. If only there was a way to draw Shrub's queen away from protecting the g7 pawn.
24...f4 25.a4 a6 26.axb5 axb5 27.Ra7
A wonderful sacrifice of the rook. If Qxa7 then d7 breaks the connection of the black queen to the g7 pawn! [27.Ra7 Qxa7 28.d7 ]
1-0

"Shrubs," said the Restless Knight "We have something to tell you. Sarge has made an offer. Any student that can learn how to program a game will earn full credit for his computer class." "Really, but what game can I program." asked Shrubs. Old Maestro said "How about a simple chess game? You already know the values of the pieces." Shrubs interjected "Now, how many fries was the king?" The chess players laughed. Old Maestro continued "All you need is a grid of 64 squares. You can put the points of each piece into the squares of the grid." "I can teach you how to make the computer know if checkmate is on the board."

Well, Old Maestro spent his days after school teaching Shrubs. They checked and double checked their logic. Everything was ready to give Sarge a demonstration for the following day. The next day came. Sarge and Shrubs sat together. Sarge made his first move, on the computer chess game, and everything went perfectly. That's when the Talker walked by, on his way out of the classroom, and said "Good Luck" to Shrubs. Now, the hairs on the back of Shrub's neck stood up. Shrubs looked over his shoulder, uneasily, until the Talker had left the room. Shrubs went to place a piece for the checkmate and up came the "Blue screen of Death". It read: "Value error. O is not a number." Sarge said "I am sorry Shrubs. You only get full credit if the game works." But Sarge was a good hearted man. "I will tell you what," said Sarge "I will give you until the end of the semester to work on your program. Good Luck. I will see you then."

Shrubs joined his friends, at Castle French Fry, who were eager to learn the outcome of the demonstration. Shrubs told them the news. Old Maestro asked Shrubs "What was the error message?" Shrubs said "O is not a number...But it is a number. I can't understand why the computer would think so badly." Old Maestro thought a silly thought to himself "Does it like fries?" Shrubs had tested the program time and time again and this was the fruit of Shrub's labor...an error message. Well my friends, sometimes things don't go as planned. However, Old Maestro smiled. He had seen this error before. "O is not a number. is correct because O is not 0. 0 is zero." This means that somewhere in your program there is a letter 'O' where there should be the number zero.

Well, Shrubs went back to the school and checked. He was looking at his program when on about the thirteenth line down he found the error. He made the correction. How the 'O' got into his program...well, you can guess and your answer is good enough for me. The same day, Shrubs showed his working chess program to Sarge and got full credit for his efforts. It was a testimony to persistence, hard work and good friends. He joined his friends, at Castle French Fry, with a smile from ear to ear. Together they shared a whole carton of fries and...Extra Ketchup!!!


and the Great Pawn Hunter leaves you with this piece of wisdom:


Life is blessed
with different things
The squirrels: tails
The angels: wings
Now, if we fight
against our role,
it can hurt our heart.
It can hurt our soul.
We all must measure
what we do best
and leave to God
all the rest.
For every life
affects the whole
and God is pleased
by trying.
