For example, 1.Kb7 g3 2.Kc6 g2 3.Re1+ AGAINST Kd3 4.Kd5 f3 5.Rd1+ Ke2 6.Ra1 f2 0-1 or 1.Rg1 g3 2.Kb7 TWO PAWNS Kf3 3.Kc6 g2 4.Kd5 Kg3 5.Ke4 f3 6.Ke3 f2 0-1.

This lesson looks at the endgame K + R vs.K + 2p.

A rook is usually better than two pawns. But there are exceptions. This class covers basic endings with a rook versus two connected pawns.

Leaders from around the world got together at the Lakeside Lodge to discuss important topics and make decisions about the game of chess. On day one, they decided not to change the colour of the pieces! The second day of the Chess Summit began the same as the first. With a short speech by Major Dooper. Besides going over the schedule, he also thanked all the guests for leaving the game room “Thank you, Captain. Very interesting. Out of each 100 so clean the night before. games, White wins 39, draws 30, and loses 31.” Then it was time for the special work Before the queen could continue, Dr. Checkle interrupted groups to start their meetings. The head with a question. “So which colour has more draws?” of the Rules Committee was the Queen Captain Bemo tried not to smile. “Well, Doc, both sides of Clubs. “Friends, our subject today have the same number of draws, of course.” is White’s advantage. Making the first The doctor nodded. “Yes, I guess they would. At least that move in a game gives White an edge part of the score is equal.” over Black. It’s like having a head start The queen continued, “Okay, we have several possible in a race. Our goal is to find a way to rule changes to consider now. Grandmaster Potatowoski, make chess more fair. Let’s begin with please explain your idea.” a report from Captain Bemo.” “Thanks, your majesty. I suggest we change the scoring The captain, who was an expert on statistics, stood and system so that winning with the white pieces counts less cleared his throat. “Good morning. As you can see on than winning with black. In my new system, Black gets 10 the handout I prepared, White has a big advantage. The points for each victory, but White only gets 9 points when figures are based on ten million master games from a they win. A draw scores 5 points for Black and 4 for White. computer database. On average, White scores 54 points White will still win just as often, but the total points scored out of every 100 games, while Black scores just 46.” for each side will be roughly even.”

Let’s ½-½ 5 points move on to another possibility. This one WHITE is my brainchild.” 1-0 9 points Everybody sat up ready to listen. They ½-½ 4 points didn’t want to miss what she had to say. “I believe”, she said with her finger in the air, “the only way to reduce White’s advantage is to limit the moves they can play on the first turn of a game. “What if White were not allowed to move a pawn two squares on the first turn? Wouldn’t that take away their edge? After all, the toughest openings for Black to defend The queen was impressed. “You’re a clever potato, sir. against begin with White advancing a pawn to the centre This is a promising proposal. The old scoring method with by either 1.e4 or 1.d4.” one point for a win and a half point for a draw is not really The queen paused for a moment and looked round the part of the game anyhow. What do the rest of you think?” table. “So, that’s the idea. Tell me, Captain Bemo. Is there King Octavius raised his hand to speak. “It seems a little any statistical support for this rule change?” complicated to me. Plus, the scoring method doesn’t make The captain must have known about her proposal before a difference in a single game. White still has the edge.” the meeting because he already had a detailed answer. Major Dooper agreed. “Spud’s scoring system might be “Well, your majesty, this is what I found in the database. good for tournaments, but what we need is a new rule that equalizes the chances for both sides in each game.” GAMES The mountie was about to say White wins 1-0 39% something else, but Dr. Checkle Black wins 0-1 31% couldn’t wait. “Hey, I’ve got it! Why don’t White and Black just Draws ½-½ 30% take turns going first? One game FIRST MOVES White starts, and the next game 1.e4 50% Black. Simple as pie.” 1.d4 32% Spud shook his head. “But, Doc, that still doesn’t solve 1.Nf3 8% the problem. Whichever player makes the first move will 1.c4 7% still have the same advantage.” 1.b4 or 1.f4 1% Dr. Checkle slumped back quietly in his chair. “Yea, 1.b3 or 1.g3 1% you’re right. I should have given that idea more thought.” all others <1%

Nearly one-third with 1.d4. Most of Luckily, the kind-hearted mountie had a polite answer for the rest begin 1.Nf3 or 1.c4. Less than three games out of him. “Yes, your highness, this is the way things should be a hundred start with any other move. So, to answer your done. In fact, it is already the normal practice at chess question, it is hard to say accurately how White would clubs and in games between friends. And at tournaments, score by only advancing a pawn one square on the first the rules state that whenever possible, players should turn. The number of examples is too small. have an equal number of Whites and Blacks.” “But here are some more facts. White still scores 54 “Very good,” said the king. “Problem solved. Let’s have a points out of 100 games with 1.Nf3. This flexible knight vote. I move that we keep the rules exactly as they are.” move often leads to positions that normally start 1.d4. It was Captain Bemo’s turn to grin this time. “I suppose “White scores 54% with 1.g3 too. A kingside fianchetto you’re right, sir. I second the motion.” frequently transposes to the English Opening 1.c4. The Queen of Clubs wasn’t surprised at all. “Okay, those “And lastly, except for the five moves I just mentioned, in favour, raise your hands.” She didn’t even have to ask if Black scores at least 50% in games with other first moves. anyone was against. “It’s unanimous, friends. The motion However, this information is not reliable because masters passes. Have a good lunch!” rarely play these other moves.” The Queen of Clubs grinned. “Well, Captain, you certainly know your numbers. We will have to do more research on this matter. Major Dooper, do you have a comment?” “Yes, ma’am. Maybe we could modify your rule so that White is also not allowed to make a knight move on the first turn. This would eliminate the strong 1.Nf3.” Captain Bemo liked the major’s suggestion. “That might actually work. Or maybe we could just ban White’s five best moves.” The queen was pleased with the discussion, but she was It was a long day at the Chess Summit. More meetings eager to go on to the next piece of business. “Thank you, were held in the afternoon and more important decisions gentlemen. It’s getting late. King Octavius has one more were made.
