Blog post number 2

Ok, technically it's 3 blog posts, but you know what, I can forget about that first one Tongue out

So I said we'd be talking about chess, but chess arbiting. Why did I choose this topic and why am I doing another blog not very long after the last? Well, this weekend, I'm arbiting at the South Wales Autumn Congress + U21 Welsh Championships. So I thought it would be fitting to give you some arbiting tips (for no real reason Laughing) and it's so soon as I can't do 1 over the weekend. So let me first give you my top 5 tips:

  1. When doing swiss pairings, remember to include the byes from the previous round in the draw!!! A simple thing, but one of the most common mistakes. Always add in those byes, they can sometimes be a pain if you forget them, to re-pair them
  2. After the default time has passed, eat your lunch!!! The quiet time is after the default time for the afternoon rounds. You have to do pairings for the afternoon rounds in the break so no time there! A side note, don't eat crisps in the playing room, they can be really loud, unless they're cheese puffs
  3. After 1 hour has passed in a round, just go round and check everything is in place. After an hour is a good time to check on things. Games most probably won't have finished, so you can check if people are recording, if clocks are 100% working, and if any people have any queries about time controls.
  4. Be patient. If you have a nightmare player, just be calm, be professional, and try and deal with the situation fairly. If someone claims a 10.2 (2 minute rule) draw, and it's tough to say yes or no, ask the opponent, would you accept a draw here? If he says yes the situation can be resolved quickly. If no, then you'll have to see how the game progresses, and make a judgement when a flag has fallen.
  5. If you make a mistake in the draw, if you can correct it by moving 2 cards, do that!! This tip is also called the Steve Boniface tip. It's not actually the most accurate way, but it's certainly most convenient and easiest to do Smile

So those are just some simple things. but this isn't the end of the blog! Oh no! I'm going to show you a draw for the first 3 rounds of a 5 round swiss. There are 20 people in the tournament. The PIN numbers are in grading order. Results are included in the draw for space convenience. Board numbers come first.

Round 1: Flip a coin to see what PIN number 1's colour is. We'll say he is white. We now pair top half with bottom half, as you always want to do in swiss pairings. Obviously for round 1 you literally do that, however in later rounds you do top half with 1 point vs bottom half with 1 point. Swiss pairings are complicated, and I'll try and explain them through out my blogs over time. This is just a little glimpse into what a pairing looks like from a set of results:

  1. 1 vs 11...1-0
  2. 12 vs 2...0-1
  3. 3 vs 13...1/2-1/2
  4. 14 vs 4...1-0
  5. 5 vs 15...1-0
  6. 16 vs 6...0-1
  7. 7 vs 17...1-0
  8. 18 vs 8...1/2-1/2
  9. 9 vs 19...0-1
  10. 20 vs 10...0-1

Round 2: We get all the winners, and pair them together, the draws together and the losses together. remember to take note of the colours due. Also note how I move the colours across, when needs be. 

  1. 7 vs 1...0-1
  2. 10 vs 2...1/2-1/2
  3. 19 vs 5...1-0
  4. 6 vs 14... 1-0
  5. 8 vs 3... 1/2-1/2
  6. 13 vs 18... 0-1
  7. 4 vs 16...1-0
  8. 9 vs 15... 1/2-1/2
  9. 11 vs 20...1-0
  10. 12 vs 17...1/2-1/2

Round 3: The last round I'll show you for now, however I'll show you the other 2 rounds in another blog. Just a quick thing, see if you can send me the correct pairing for round 4, using the results shown below. Now we may have to float players up or down, due to an odd number of people on a certain score. A note on that. In a 6 or less round tournament, you up-float top and down-float the median, however in 7 or more rounds, you would up-float and down-float the median. Since this is a 5 round swiss, we're up-floating the top. Rounds 1 and 2 are nice and easy, however round 3 starts to cause some problems, unless you're really lucky:

  1. 1 vs 19
  2. 2 vs 6
  3. 18 vs 10
  4. 14 vs 7
  5. 3 vs 11
  6. 5 vs 4
  7. 9 vs 8
  8. 15 vs 12
  9. 17 vs 13
  10. 16 vs 20

That round 3 pairing was a bit awkward, especially around the 1 pointers, and who to up-float from them. Since 4 and 14 had already played, it caused some problems. If you have any queries about the pairings above, or you have the round 4 pairings, then please do message me. You'll get a mention if you get it right!!! 

I'll be away the weekend, so won't be on chess.com much, so have a good weekend all, and might see you at South Wales Autumn Congress if you're going (which won't be many if any at all!) 

I will see you guys next time here at brfc's blog!

P.S! Nearly forgot pointless facts of the blog:

Americans on average eat 18 acres of pizza every day.

In Italy, it is illegal to make coffins out of anything except nutshells or wood.

Intelligent people have more zinc (Zn) and copper (Cu) in their hair.

Now it's really time to say bye!! BYE!
