	The term ''leech'' is used in SuperMemo to refer to ill-formulated [[Glossary:Item\|items]]. An [[Glossary:Element\|element]] is called a [[Glossary:Leech\|leech]] when it meets user-defined ''leech criteria'' such as the number of [[Glossary:Lapse\|memory lapses]] and the current [[Glossary:Interval\|interval]]. These parameters can be defined when using '''[[View menu\|View]] : [[View menu#Other\|Other]] : Leeches''' (''Shift+F3''). An [[Glossary:Element\|element]] becomes a [[Glossary:Leech\|leech]] when the number of [[Glossary:Lapse\|memory lapses]] passes a defined limit. However, an [[Glossary:Element\|element]] is no longer considered a [[Glossary:Leech\|leech]] if it is remembered beyond a certain [[Glossary:Interval\|interval]] (independent of the number of [[Glossary:Lapse\|lapses]]).

	*'''Auto-postpone''' - upon encountering a [[Glossary:Leech\|leech]] during repetitions, SuperMemo will automatically reset the learning parameters of the [[Glossary:Element\|element]] and schedule it for repetition after a sufficiently long [[Glossary:Interval\|interval]]. Quite often, taking a break from repetitions of a [[Glossary:Leech\|leech]] may help overcome an erroneous memory pattern. For example, if you tend to confuse Nigeria and Niger on the African map, taking a 50-100 day break from making repetitions on this subject may actually resolve the confusion by cleaning your memory from erroneous traces. Once you consciously re-memorize the position of both countries on the map, the problem may be solved once and for all. '''Important!'''

	'''Include semi-leeches''' checkbox can be used to tighten the criteria for a leech warning.

	A new powerful tool against leeches is a possibility of exporting your leeches to a handheld device (see: [http://~~supermemo~~.com/articles/soft/pocket.htm Revolution in the pocket]). Although, it may seem that pocket repetitions are usually done in conditions of lesser focus, working in the leech-only mode sets your brain onto an emergency alertness level.

However, you should remember that part of the leech problem is repetition that is too frequent (i.e. causing the [[Glossary:Spacing_effect\|spacing effect]]). This is why '''Auto-postpone''' and '''Auto-forget''' are so efficient. This is also why [[Glossary:Leech\|leeches]] are much less of a problem in heavily overloaded [[Glossary:Incremental_reading\|incremental reading]].

	Leech parameters are stored between sessions in the [[Collection files\|file]] ''<supermemo folder>\<systems>\<collection name>\collection.ini'' in the section ''[Leech]''		Leech parameters are stored between sessions in the [[Collection files\|file]] ''<supermemo folder>\<systems>\<collection name>\collection.ini'' in the section ''[Leech]''

	*If you cannot make an evaluation without actually responding to the leech question, choose '''Show answer''' and reevaluate the leech. If you recall the answer correctly, you should rather grade your response and defer your action until the next repetition (chances are, your leech will fall out from the leech criteria)		*If you cannot make an evaluation without actually responding to the leech question, choose '''Show answer''' and reevaluate the [[Glossary:Leech\|leech]]. If you recall the answer correctly, you should rather grade your response and defer your action until the next repetition (chances are, your leech will fall out from the leech criteria)
	*The most efficient method of dealing with leeches is to choose '''Edit'''; however, you will need lots of experience to figure out how to properly formulate the material, split it into smallest possible components and use mnemonic techniques (see: [http://~~supermemo~~.com/articles/20rules.htm 20 rules of formulating knowledge])		*The most efficient method of dealing with [[Glossary:Leech\|leeches]] is to choose '''Edit'''; however, you will need lots of experience to figure out how to properly formulate the material, split it into smallest possible components and use mnemonic techniques (see: [http://super-memory.com/articles/20rules.htm 20 rules of formulating knowledge])
	*If you do not know what to do with a given leech, you can just press ''Esc'' and continue with repetitions. '''Warning!''' This can easily become a habit and all the idea behind the leech alert will be defeated! Before using ''Esc'' becomes automatic, read this text carefully and learn to make your leech-related decisions!		*If you do not know what to do with a given [[Glossary:Leech\|leech]], you can just press ''Esc'' and continue with repetitions.
