I recently won a game at chess.com in speed chess. My opponent was Qasaal of Somalia who played black. My opponent made a number of mistakes which allowed me to win quickly. Here are the moves of the game along with my commentary:
1. e4 e5
2. Nf3 Nc6
3. Bb5 a6
4. Bxc6 bxc6
Black makes a mistake. He should play dxc to open the c8-h3 diagonal for his bishop and d-file for his queen.
5. d4 Bb7
6. dxe Rb8
This move by black is not the best. It is better to develop the kingside bishop and knight to prepare for castling.
7. Nc3 c5
With this move black opens a diagonal for the queen bishop but the king knight and bishop are still on their original squares.
8. 0-0 Nh6
9. Bxh6 gxh6
I capture the knight to weaken black's kingside.
10. Nd5 c6
This is a mistake. My knight wants to go to f6. To stop this, black must play Bg7.
11. Nf6+ Ke7
Black's move is forced.
12. Qd6#
I achieve a quick and decisive victory because of black's lack of development, weakened pawn structure and inability to prevent moves such as Nf6+. Though material is almost even, black cannot protect his king. This in turn leads to his rapid downfall.

Peer Gynt
Peer Gynt is the title of a beautiful play by the Norwegian playwright Henrik Ibsen. It is also the name of the music composed for the play by the Norwegian composer Edvard Grieg upon the request of Henrik Ibsen. The play consists of five acts and in the original Norwegian language is like a long poem.
Peer Gynt is the son of the formerly highly-regarded Jon Gynt. Unfortunately, Jon Gynt wastes all his money on parties and luxuries until nothing is left. He has to leave his farm as a travelling salesman, leaving his wife and son in debt. Åse, Peer's mother, wishes to raise her son to restore the family's lost fortune, but Peer is a lazy dreamer who fails to live up to his mother's wishes.
Later in the play Peer marries a woman named Solveig but he is banished because he marries her against her family's wishes. He has a bad reputation and Solveig's family wants nothing to do with him. After he is banished, Peer's mother, Solveig and Solveig's father look for him in the mountains. They cannot find him.
Peer builds his own cottage in the hills. Solveig appears and insists on living with him. She has made her choice and has no plans to return. Peer is delighted and welcomes her warmly. However, Peer starts to remember all his previous sins and cannot face Solveig. He tells Solveig he has something heavy to collect, returns to his childhood home in time for his mother's death and then travels overseas.
Peer spends years abroad where he engages in several occupations. These include the role of a slavetrader, missionary, businessman and historian. The reader is aware that much of Peer's life is a dream. He has a vivid imagination and many of his experiences are not reality.
In the final act, Peer returns home as an old man. He has lost all his possessions and feels that he is nothing. At that moment, Solveig starts to sing. The cabin he built is near but he does not dare enter. He feels guilty for having abandoned her. In one of the most touching parts of the entire play, Peer asks her, "Where has Peer Gynt been since we last met? Where was I as the one I should have been, whole and true, with the mark of God on my brow?" She answers, "In my faith, in my hope, in my love." With these words, Peer understands that she has never abandoned him and truly loves him.
Peer Gynt is a fascinating play which explores a number of themes. These include love and duty, sin and forgiveness, and reality and imagination. The themes of love and forgiveness are clearly expressed in Solveig's words at the end of the play.

The low vowel in Canadian and American English
A feature of Canadian English is the pronunciation of borrowed words with low vowels. Borrowed words such as pasta, Mazda, drama, and taco are often pronounced with the front vowel of "cat" whereas Americans tend to use the back vowel of "far."
Charles Boberg found that for 15 such borrowings, the Canadian pronunciation was always more likely than the American pronunciation to have the front vowel . For example, 82% of his American informants pronounce "panorama" with a front vowel in the third syllable, compared to 94% of Canadians. In a parallel manner, 5% of the Americans in his study pronounced pasta with a front vowel in the first syllable, compared to 81% of Canadians.
The following table provides a list of items Boberg used. For nearly each word, at least 70% of his Canadian informants had a pronunciation with the front vowel, with the exception of "macho," "taco," and "Vietnam." In these cases, however, the Canadian pronunciation was still more likely to use the front vowel than the American pronunciation was.
American pronunciation with low back vowel/Canadian pronunciation with low back vowel (in the case of multisyllabic words, this applies to the stressed syllable)
panorama 18% 6%
Pakistani 21% 9%
Iraq 28% 7%
pyjamas 58% 15%
plaza 75% 16%
Colorado 86% 26%
Vietnam 86% 44%
taco 88% 48%
Slavic 89% 15%
Mazda 93% 18%
macho 93% 68%
llama 94% 29%
pasta 95% 19%
lava 95% 23%
drama 95% 25%
Here is a list of many more borrowed words that tend to have the front vowel in Canadian English:
places- Acapulco, Basque, Colorado, Iran, Iraq, Kazakhstan, Nevada, Slavic, Slovakia, Vietnam, Yokohama, Yugoslavia
foods- avocado, bratwurst, cilantro, goulash, nacho, pasta, pecan, pistachio, souvlaki, taco
products- Datsun, Fiat, Lada, Mazda, Nissan, Yahoo
It is clear that Canadians are far likelier to use the front vowel in borrowed words than Americans. In many cases, the use of the front vowel is rare in American English. As a result, this is a feature which serves to distinguish Canadian and American English.

Queen and Knight
I recently won a game at chess.com in which my queen and knight combined to mate. My opponent was Qais71 of New Zealand who played black. Here are the moves of the game along with my commentary:
1. e4 d5
2. exd Qxd5
This opening is known as the Scandinavian Defence. Black has an open d-file but the queen comes out early.
3. Nc3 Qd8
This retreat by black is not the best. A more popular move is Qa5.
4. Nf3 g6
5. Bc4 Bg7
6. 0-0 e6
Black protects the f7 square.
7. Re1 Ne7
Here it is more common for black to play Nf6. He probably wants to keep the diagonal open for the bishop on g7.
8. d3 0-0
9. Be3 b6
10. Qd2 Bb7
I do not want black to capture my knight and destroy the pawn structure around my king.
11. Ng5 a6
12. Bxe6 Qd6
Black does not accept my bishop sacrifice because I can then play Nxe6 which forks his queen and rook.
13. Bxf7+ Rxf7
I take the pawn to further expose the black king.
14. Nxf7 Kxf7
White has an extra piece but I have two extra pawns and the black king is exposed.
15. Bh6 Kg8
Black does not want the white queen on h6.
16. Bxg7 Kxg7
17. Qe2 Nf5
18. Ne4 Qc6
I cannot move my knight on my next move because then black can mate.
17. f3 Nd7
Black finally frees his rook on a1.
18. Ng5 Nf6
19. Ne6+ Kh6
20. Qd2+ g5
After my twentieth move, mate is unavoidable.
21. Qxg5#
The keys to victory in this game are my protected king, ability to expose the black king and coordination of my knight and queen. Black has a material advantage but it is of no consequence. My pieces are better developed than his.

Acronyms
Acronyms are abbreviations formed from the initial letters of a name or phrase. Long names and phrases are often abbreviated. Acronyms are often more common than the names or phrases that they represent.
The acronym UN is a well-known acronym for the United Nations. The acronym UNICEF is more common than United Nations International Children's Emergency Fund. UNESCO is an acronym for United National Educational, Scientific and Cultural Organization. As it is a long name, the acronym is very common.
The province of British Columbia, Canada is often referred to as BC and the city of Los Angeles is often LA. The United Kingdom is often called the UK. However, Great Britain is not abbreviated to GB in spoken language.
In certain cases, acronyms become so popular that people may not even realize that they are acronyms and may actually think of them as words. Examples include laser, radar and scuba. They mean "light amplication of simulated emission of radiation," radio detection and ranging," and "self-contained underwater breathing apparatus."
Foreign acronyms are the name of the Dutch airline KLM and the Swedish car company Saab. KLM is Dutch for Koninglijk Luchtmaatschappij which means Royal Air Company and Saab is Swedish for Svenska Aeroplan Aktiebolaget which means Swedish Airplane Limited. Though Saab is associated with cars, it originally manufactured planes and still does today.
Acronyms are abbreviations that are often more common than the names and phrases that they represent. This is particularly true for long names and phrases. Some acronyms have become so popular that they function as words because many are not aware that they are in fact acronyms.

Western and Eastern Norwegian Dialects
Two of the main Norwegian dialects are the western and eastern. The eastern dialect is spoken in the capital Oslo and the western in Bergen, the second largest city of Norway. These dialects exhibit a number of differences in grammar, vocabulary and pronunciation. I wish to focus on pronunciation.
One difference between the two dialects is with respect to pitch. This is a feature which Norwegian shares with Swedish. Disyllabic words with identical pronunciation are distinguished by pitch alone. The two types of pitch are called Tone 1 and Tone 2. For example, the word bønder (farmers) has Tone 1 and bønner (beans) has Tone 2. The two words sound otherwise alike because the "d" of bønder is not pronounced.
However, the two dialects have different types of pitch. The eastern Norwegian dialects have a low-tone accent and the western Norwegian dialects have a high-tone accent.
The eastern Norwegian dialects are called low-tone accents because they have a low flat pitch on the first syllable of tone 1 followed by a rising pitch on the second. Tone 2 has a high falling pitch on the first syllable and a low pitch at the beginning of the second.
The western Norwegian dialects are called high-tone accents because they have a high pitch on the first syllable of tone 1 followed by a low pitch at the beginning of the second. Tone 2 has a rising pitch on the first syllable and a falling pitch at the beginning of the second.
The liquids are also pronounced differently in the two dialects. The lateral of words such as tolv (twelve) and hals (throat) is velarized in the eastern Norwegian dialects but not in the western ones. The rhotic sound of tre (three) and rot (root) is an alveolar trill in the eastern Norwegian dialects but a uvular trill or fricative in the western ones. In words such as først (first) and norsk (Norwegian) the eastern Norwegian dialects have a retroflex alveopalatal fricative but the western Norwegian dialects have a uvular followed by an alveolar fricative.
In words beginning with sl-, the western Norwegian dialects pronounce them as in English. The eastern Norwegian dialects, however, pronounce the "s" as a retroflex alveopalatal fricative. This is also the case when the two letters occur across syllable boundaries. This sound can be heard in words such as slott (castle) and also veksle (to exchange).
Another difference between the eastern and western Norwegian dialects is the pronunciation of the diphthong found in words such as vei (way) and hei (hi). In the dialects of eastern Norway, the diphthong is similar to that of the diphthong in words such as "why" and "my." In western Norway, the diphthong is similar to that heard in words such as "way" and "may."
The two most widely-spoken dialects of Norway, the western and eastern, have many differences in grammar and vocabulary. However, they also have well-known pronunciation differences. As a result, Norwegians can easily identify speakers of these two dialects.

Piet Hein
Piet Hein was a Danish poet who lived from 1905 to 1996. One of his poems is titled "A Psychological Tip."
A Psychological Tip
Whenever you're called on to make up your mind,
and you're hampered by not having any,
the best way to solve the dilemma, you'll find,
is simply by spinning a penny.
No - not so that chance shall decide the affair
while you're passively standing there moping;
but the moment the penny is up in the air,
you suddenly know what you're hoping.
This is a short poem which suggests that by spinning a penny, we can discover what we really want. In other words, we may not need to spin the penny at all because we may make up our minds before the penny does. The rhyme scheme of the poem is a,b,a,b,c,d,c,d. Piet Hein's poems reveal many truths about life. "A Psychological Tip" is no exception.
