Training in any kind of skill, ability, or knowledge that will likely later [[SomedayThisWillComeInHandy come in handy]]. Much like ChekhovsGun, ChekhovsSkill covers instances where a character takes time in-story to become proficient at something.

If the hero takes time to teach his [[LoveInterests sweetie]] a self-defense Judo throw during the beginning, expect this DistressedDamsel to throw the {{Mook}} [[StandardFemaleGrabArea holding her]] into a SharkPool during the climax.

This is a counterpoint to SuddenlyAlwaysKnewThat, as proficiencies are gained and learned rather than mentioned or pulled out of [[AssPull thin air]]. Taken to extremes, ChekhovsSkill can be used to {{justif|iedTrope}}y ImplausibleFencingPowers or turn the FarmBoy into a [[GunKata gun toting]] BadAss. In frustrating cases, it might go the way of ForgottenPhlebotinum and never see use again. Used well, it can lead to some satisfying [[HeroicBystander heroics from unexpected places.]]

ChekhovsSkill can also be used as a catalyst for other plot elements by having one character teach another, and getting some good CharacterDevelopment out of it as well. Or even drive a plot as [[SeekerArchetype the seeker]] looks for a {{mentor|Archetype}} to teach them ChekhovsSkill. If the skill is too complicated to be perfected so quickly, see InstantExpert.

If it is not a skill taught or otherwise demonstrated to the individual in question, then it is a ChekhovsHobby. In the hobby, the skill is mentioned through dialogue and never takes up more plot than that. In the skill, even if the character hasn't perfected the DangerousForbiddenTechnique it still shows them training for it.

If the character is shown training for a skill but repeatedly fails at it until everything depends on them getting it right, that's CrisisMakesPerfect. If they've been compulsively using their ability since they got it, it's NewAbilityAddiction.

* American astronautics:
** During the Gemini XII mission, the rendezvous radar, which was to have guided the spacecraft to docking with the Agena target vehicle, failed. Fortunately, co-pilot Buzz Aldrin had specialized on space rendezvous during his doctoral studies at MIT (he was sometimes known as Dr. Rendezvous). He "simply" pulled out a sextant and a set of charts he had developed, and proceeded to feed correct target distance measurements into the computer.
** Astronaut Jim Lovell, during his flight on Apollo 8, remarked that he could use a portion of the Earth as a reference point to control his spacecraft's attitude should his guidance computer fail. During his Apollo 13 flight, an explosion forced the crew to shut down their guidance computers to conserve power. When he had to fire his engine to correct his craft's trajectory, he used the very same technique he came up with a year and a half earlier.
** When Apollo 12 was struck by lightning during launch, taking out the fuel cells, the command module instrumentation, and the telemetry feed which ground control relied on, it looked like they were going to have to abort because no one knew how to fix the telemetry (which was fundamental to dealing with the other problems). No one except EECOM John Aaron, who had happened to have seen the same error during a test a year earlier and tracked it down in his spare time, and knew the simple but incredibly obscure procedure that would restore telemetry.

* Steve Jobs took a course in calligraphy at college. It later proved invaluable in Apple pioneering the Graphical User interface. Now think of how far CGI has gone ahead since that development.
* Air Canada Flight 143, known as the [[http://en.wikipedia.org/wiki/Gimli_Glider "Gimli Glider,"]] ran out of fuel mid-flight due to to a combination of technical failures and ground crews making errors converting from imperial to metric units when refueling the plane. The loss of both engines effectively turned the plane into a glider. The captain, Bob Pearson, happened to be an experienced glider pilot. He managed to land the plane safely at Gimli, an abandoned air force base turned into a drag strip.
* In mathematics, the associativity and commutativity. You learn them at primary school and then they don't show up again… until you learn about matrix algebra or hypercomplex numbers, which need not be associative or commutative.
* Even if it's been ''decades'' since a person's taken a foreign language in high school, it can still resurface and come in handy.
