The Norwegian Chess Championship (NM i sjakk) is an annual tournament held in Norway during the month of July, in order to determine the national chess champion. The tournament is held at different venues each year as part of the Landsturnering (National tournament). Clubs may bid for this tournament, and is awarded by the Norwegian Chess Federation.

Rules for participation and other classes

The rules for participation are governed by the Norwegian Chess Federation.

The championship ("Elite") section is closed to the top rated players. In order to play for the most prestigious title of national chess champion, the player must meet at least one of the following criteria:

• Won the Norwegian Championship in one of the three preceding years.
• Finished third or better in last year's championship.
• Won the national championship in the Junior section the previous year.
• Finished second or better in the Master section (the second highest section, immediately below Elite) the previous year.
• Made a tournament result which grants or would grant (for players who already have an IM title) a norm for the title of International Master during the previous year.
• Have a sufficiently high Elo rating (as of 2007 this limit is at 2300).
• Been deemed otherwise eligible for participation by the Elite Committee of the Norwegian Chess Federation.

In general, an even number of participants is sought in the championship section to prevent bye from occurring.

However, the Landsturnering has several sections for lower-rated players, as well as sections for different age groups. In general, players must be members of the Norwegian Chess Federation, or a club affiliated with the federation, although exceptions may be made for participation if the person is a member of another national chess federation. Non-members can under no circumstance be awarded a championship title.

The current regulations provide for following age categories:

• Senior A (over 60)
• Senior B (over 60, rating under 1500)
• Junior A (under 20)
• Junior B (under 20, rating under 1500)
• Cadet A (under 16)
• Cadet B (under 16, rating under 1250)
• Lilleputt (under 13)
• Miniputt (under 11)

The Senior, Junior and Cadet categories are split into an "A" and "B" group by rating, but are joined together if either of the groups have less than 10 participants. A separate section for Junior B has not been arranged in the last few tournaments, and in 2008 the number of entries for that section was zero.

The rating sections are open for players of all age groups, and are divided into the classes

• Mester (Master) (rating over 2000)
• 1 (rating 1750-1999)
• 2 (rating 1500-1749)
• 3 (rating 1250-1499)
• 4 (rating 1000-1249)
• 5 (players not qualifying for a higher section)

A player cannot be required to play in a higher class than what the last rating list indicates, however a player may elect to play up if a sufficiently high rating was obtained on any of the four official rating lists during the year. In addition, players may elect to play in a higher section if they scored at least 60% in that same class the previous year, if they were in the top 7% of the class below the previous year, or if they won the Norwegian Grand Prix tournament series for the rating class below in the previous year. In addition, winners of the individual circuit championships and the champion of Northern Norway are automatically qualified for play in the Master class, regardless of rating. The top two finishers of the Master class qualify for next year's championship section.

Arrangement

In the past ten years, the championship section has had approximately 20 players. If there are at least 16 players, it is arranged as a nine-round Monrad tournament, a system similar to the Swiss system tournament. The official Norwegian Chess Federation policies also allow the tournament to be arranged as a round-robin with 10 or 12 players.

If two or more players are tied for points at the end of the tournament, the tiebreak rules depend on the section. In most sections of the Landsturnering, the regular rules of tiebreak points in Monrad are used. That is a modified Buchholz system, first the sum of a player's opponents' scores, except the two weakest, determines the player's tiebreak points. If still tied, the second weakest and then the weakest scores are added to the tiebreak points. If still tied, the Neustadtl score, that is the sum of defeated opponents' scores plus half of drawn opponents' scores is used.

In the Championship, Junior, Cadet and Senior sections however, a tied score will bring about a play-off for the title within 60 days after the end of the main tournament. If there are two players in the play-off a match of two games with a full time-limit is played, if still tied two and two rapid games of 25 minutes for the game and 10 seconds extra per move are played until there is a winner. If there are three or more players in the play-off a small round-robin is arranged between them.

Past events and champions

This table summarizes all past championship events. The tournament was not arranged in 1928 and 1939 due to Nordic Championships being arranged in Oslo those years, nor was there any event between 1940 and 1944 when Norway was occupied by Nazi Germany.

The number of participants is the number of players in the entire Landsturnering, not just the championship section. The champions are listed along with the club they represented when they won the championship. Titles decided by play-off matches due to equal scores in the main tournament are noted.
