Taggdefinitioner

Läs igenom sidorna Lista över taktikmotiv och Lista över positionella motiv innan du börjar tagga problem. Dessa sidor innehåller en kort beskrivning och exempel på varje taktikmotiv och tillhörande taggar. Vissa schackförfattare har något olika definitioner för vissa motiv, så beskrivningarna på sidan kan skilja sig något från vad du har läst på andra ställen. I sådana fall bör du försöka använda Chess Tempos definition för att hålla taggarna så konsekventa som möjligt.

Hur tagg-omröstningen fungerar

Tagg-omröstning summerar alla röster för och emot en viss tagg på ett problem, och om det finns fler röster för taggen än emot den, kommer problemet att markeras med den taggen. Det innebär att om du redan ser ett problem med en tagg som du håller med om, kan det vara bra att lägga till din röst för taggen även om problemet redan har markerats med den taggen. Anledningen till detta är att om det bara fanns en röst för taggen och någon annan felaktigt röstade mot taggen, skulle taggen bli inaktiv (färgad röd), men om du lägger till din röst för taggen skulle det krävas två röster mot taggen för att inaktivera den.

Användare kan bara rösta på en viss tagg en gång per problem, men användare KAN rösta på flera olika taggar per problem, så om du ser mer än en lämplig tagg för ett problem, vänligen rösta på alla.

Antalet röster för och emot en tagg visas när du håller muspekaren över taggen. Du kan klicka på + eller - för att lägga till röster för eller emot en befintlig tagg, eller så kan du använda +-knappen under taggarna för att rösta på nya taggar. De tillgängliga taggarna visas då.

På listan över redan tillämpade taggar kan du klicka på taggnamnet för att se en beskrivning av taggen om du vill kontrollera din förståelse av taggdefinitionen innan du röstar. Om du inte har röstat på en tagg tidigare eller inte har röstat nyligen så visas också beskrivningsvyn, även när du klickar direkt på upp-/nedrösterna för att lägga till din röst.

När du väljer en ny tagg visas taggarna i en mappstruktur i taggvalsfönstret. Mappar på högre nivå, såsom "Non-mate Motifs", kan inte röstas på direkt, men vissa mappar är också taggar som kan röstas på. I mappen "Non-mate Motifs" finns till exempel en mapp som heter "Discovery". Du kan rösta direkt på mappen "Discovery" (klicka på namnet istället för ikonen för att expandera/minimera för att rösta på en mapp-tagg). Om du röstar på underordnade taggar till en sådan taggbar mapp-tagg kommer du också att rösta på alla taggbara överordnade taggar som leder till att den underordnade taggen röstas på. Till exempel finns det en tagg "Discover Checks" i mappen "Discovered Attack" som finns i mappen "Discovery". Taggen "Discover Checks" har alltså den fullständiga mappvägen "Tactical Motifs -> Non-mate Motifs -> Discovery -> Discovered Attack -> Discoverer Checks". Om du röstar på "Discoverer Checks" kommer din röst också att tillämpas på "Discovered Attack" och "Discovery". Detta ger större flexibilitet i den anpassade sökningen, eftersom det innebär att genom att rösta på "Discoverer Checks" kommer andra också att kunna hitta objekt som du har taggat på detta sätt via de högre nivåerna "Discovery" eller "Discovered Attack". Nedröster fungerar på samma sätt som uppröster i mappstrukturen, så en nedröst på "Discoverer Checks" kommer också att nedrösta dess relevanta överordnade nivåer.

One of the reasons we tag positions is to allow users to find positions that contain a tactical motif that they want to study. For example, if a person wants to study pins, they can create (or use a pre-made) custom set which targets pins. The search results will include only those positions that have previously been tagged as pins. This is important to remember when tagging a position. Let's say that you are solving a tactical puzzle and you want to add the tag 'pin' to that particular problem. Before adding that tag, ask yourself the following question: If I were searching for pins, is this an important position that I would want to see in my search results? If the answer is "yes", then add the tag. If the answer is "no", then the tag should not be added.

Tag modifiers

Tag modifiers allow more specific versions of tags to be represented without creating a massive number of new top level tags. For example it may be useful to recognize that a motif occurs with check, or that a particular piece was moved during the tactic. For example a Fork with check could be presented by Fork[Check,Knight] indicating that a Knight delivered a fork with check.

Modifiers can only be added when creating a new tag. You can't add a modifier to a tag that has already been added to a problem. This means if there is an existing Fork tag with no modifiers, and you want to add a Fork[Check,Knight] tag, you would need to add a new tag using the '+' button , and then on the add tag panel, choose the Check and Knight modifiers. We also want to avoid an acculumation of the same tag with different sets of modifiers , so if you believe your new tag with modifiers is the most specific available, then you should also vote down Fork tags without modifiers. The tag without modifiers is not wrong, but your new tag is more specific, so we would prefer that it becomes the primary way of tagging the Fork on the problem. People using tag searches based on 'Fork' will still find the modifier version, with the added bonus of also being able to search for problems with more specific versions involving check or the specific piece involved. If other taggers agree with your modifiers, they can click directly on your modifier version of the tag to vote it up without having to add their own modifier version, and they can also vote down the less specific version.

We currently support three types of modifiers, the Check modifier, the attacking piece modifier (Pawn, Bishop, Knight, Rook, Queen , King) and the Prophylaxis modifer. The Check modifier is to be used when the motif involves checking the opponent king. The attacking piece modifier designates the piece(s) involved in the attack. The Prophylaxis modifier provides a way of indicating that a move is required in order to protect against a potential attack from your opponent. It is most commonly applicable on mixed mode defensive problems, but may also be relevant in non-defensive tactics.

Please note that piece modifiers (Pawn, Bishop, Knight, Rook, Queen , King) only refer to the moving piece, please don't use these to denote the type of pieces attacked. So for example a Fork[King] is a fork made by a King on two pieces, NOT a fork on a king. Similarly Pin[Rook] is pin where a rook is pinning another piece, NOT a pin on a rook. You can use the piece modifier for opponent pieces when combined with the Prophylaxis modifier, indicating the opponent piece is the piece capable of making the potential threat. Similarly if a move is a prophylactic move that defends against check from your opponent, then tagging with both Prophylaxis and Check as modifiers is also fine.

For a small number of tags , modifiers will be redundant , as we decided to have a specific tag that overlaps with a modifier. For example 'Discoverer Checks' could be 'Discovered Attack[Check]'. To avoid clutter it is best to avoid marking 'Discoverer Checks' with the Check modifier, given the name already holds this information.

Användning av positionsmotiv

Initially, positional motifs were only available for tagging positions in the Guess the move feature. However we now allow positional tags to be used in chess problems. When deciding if a positional tag could be used on a problem, please try to limit tagging to features that were relevant to the problem solution. For example, if a tactical position has connected pawns, but they don't feature in the tactic, then they should not be tagged. If however, the tactic involves utilising an advanced pawn to gain material, it is possible the connected nature of your pawns was relevant, and if that is the case, they should be tagged. Some positional motifs will tend to be more commonly associated with tactics than others. For example motifs in the positional list like 'Rook On 7th Rank', 'Pawn Storm', 'Rook Lift' will tend to be more commonly featured in tactics problems than some of the less aggressive positional tags.

Tags for tactical threats that are not played out

Sometimes a tactic involves the threat of a particular tactical motif , but the tactical motif itself is not actually played out on the board (for example the opponent gives up a minor piece to avoid a fork on more valuable material). In these situations it is ok to tag the problem with the threatened tag as long as the threat was important in making the tactic work. Incidental threats that are not relevant to the main line should not be tagged.

Needs more Moves and Needs different opponent moves tags

These are special purpose tags that prompt the user for a move suggested the user feels would lead to an improvement in the tactic.

'Needs more moves' should be used when the problem finished early and would benefit from more moves in order to force the user to see the point of the tactic. You are asked to enter a single move which would be the next move in the move sequence (usually an extra opponent move). While you may feel that multiple extra moves are required, you are only asked to enter the very next move. This will make the automatic extension of problems much easier to handle (although it may mean that sometimes a subsequent move extension vote may need to be made, in many situations the auto-extension will be able to fill in more than one extra move once the first move has been provided). So for example if the the move sequence ended after two user moves with 1...Nf3 2.Rxf3 Qxf3 and you felt that 3.Bxf3 Rxf3 should have been played, then you would use the 'Needs more moves' tag and enter 3.Bxf3 as the extra move.

The 'Needs different opponent move' tag should be used when you believe a move played by the opponent prevented the main point of the problem being shown, or that a different opponent move would have been more instructive. In this case you enter the the move that you believe should replace an existing move, for example if the main line was 1...Nf3 2.Rxf3 Bxf3 (with white giving up the rook to avoid losing the queen in the future), and you think that forcing the user to find the longer queen winning move would be more instructive, then you could suggest 2.Rf4 which might be a move that would force black to prove they can see the more difficult queen winning sequence. Note that the 'Needs different opponent move' tag should not be used to suggest 'silly' moves that a human wouldn't play just in order to reveal a pretty tactical line. The suggested move should always be a move that gives the winning side a chance to go astray and miss the win (even if the move might have lower computer evaluations in the longer term).

If you are unsure of the quality of your suggested move then using an engine to check your analysis would be beneficial. There may also be some situations where there is no clear good move and a human player would probably just resign. A good guidelines here (and in other situations) is to suggest the move that poses the most difficult questions of the opponent (which in this case is you).

As with the standard tactical motif tags, it is very useful for you to add an extra 'for' vote for a 'need more moves' or 'needs different opponent move' tag if you see an improved move suggestion that you agree with. Not only does this help keep useful suggestions around in the situation where other users incorrectly vote against the tag, but once auto-adjustment of problems is implemented, the problems that are processed first will be the ones with the most tags.

Vanliga taggningsfel

Ogarderad pjäs : Detta bör endast användas när en pjäs hänger och kan tas i problemets första drag. Det ska INTE användas när du spelar en gaffel/dubbelattack eller en skenschack (skewer) och sedan tar en pjäs i nästa drag.

Bakre radmatt (Back Rank Mate) eller svag bakre rad (Weak Back Rank) : Ett problem ska endast märkas med en av dessa, inte båda. Om matt uppstår i lösningen, använd Back Rank Mate. Om material vinns på grund av hot på bakre raden, använd Weak Back Rank.

Blockering eller interferens? : Dessa är inte samma sak och bör inte användas för samma taktiska idé. Läs beskrivningen av taktiska motiv för att se skillnaden. Kort sagt blockerar en blockering en flyktruta för en motståndares pjäs (vanligtvis kungen) medan en interferens avskär en eller flera av motståndarens kommunikationslinjer mellan pjäser eller mellan en pjäs och en ruta.

Avledning eller attraktion? : Ofta förväxlas dessa två begrepp med varandra. Avledning (Distraction) innebär att en pjäs flyttas bort från sin defensiva uppgift så att något annat kan attackeras, medan attraktion innebär att en värdefull pjäs dras närmare så att den kan attackeras mer.
