L'attaque et l'échec à la découverte

Un nouvel article a été publié sur https://www.apprendre-les-echecs.com/attaque-echec-decouverte/

L'attaque et l'échec à la découverte

L’attaque à la découverte est une attaque réalisée non pas par la pièce qui bouge mais par une pièce à longue portée (Tour, Fou ou Dame) située derrière celle-ci. Lorsque cette attaque est effectuée sur le Roi, on parle d’échec à la découverte.

L’attaque à la découverte fait partie des combinaisons tactiques de base à connaître absolument pour mieux jouer aux échecs.

Le principe de l’attaque à la découverte

Le but d’une attaque à la découverte n’est pas juste d’espérer que l’adversaire ne verra pas cette attaque (même si cela arrive). Le but est de trouver un emploi à la pièce qui se déplace, comme l’attaque d’une deuxième pièce adverse, afin de mettre l’adversaire en difficulté.

Le diagramme suivant illustre ces possibilités:

r5k1/3q1ppp/8/8/8/3B3P/5PP1/3R1RK1 w - - 0 1

[Result "*"] [SetUp "1"] [FEN "r5k1/3q1ppp/8/8/8/3B3P/5PP1/3R1RK1 w - - 0 1"] Un coup comme 1. Be2 serait inutile, car les Noirs vont sans doute voir l’attaque sur leur Dame et la déplacer. *

[Result "*"] [SetUp "1"] [FEN "r5k1/3q1ppp/8/8/8/3B3P/5PP1/3R1RK1 w - - 0 1"] Une meilleure idée serait 1. Be4 qui attaque la Tour noire en même temps que la Dame. Après Qc8 2. Bxa8 Qxa8 les Blancs ont gagné la Tour contre leur Fou. *

Des exemples tirés de parties réelles

L’exemple suivant est tiré de la partie jouée entre Aleksandra Goryachkina et Carla Heredia Serrano lors de la 2e ronde des Olympiades 2016:

r7/1p1r2kp/p2B1p2/q3p1p1/2Q1P3/2N4P/PP3PP1/3R1K2 w - - 0 23

jQuery(document).ready(function($) var selector = '#' + "rpbchessboard-5b6b226b06bc3-5" + ' .rpbchessboard-chessboardAnchor'; $(selector).removeClass('rpbchessboard-chessboardAnchor').chessboard("position":"r7\/1p1r2kp\/p2B1p2\/q3p1p1\/2Q1P3\/2N4P\/PP3PP1\/3R1K2 w - - 0 23","squareSize":32,"showCoordinates":true,"colorset":"original","pieceset":"cburnett"); );

23.Ff8+ attaque la Tour en d7 (qui n’est pas protégée) en découvrant l’attaque de la Tour en d1, et gagne une qualité.

Dans la partie qui opposa Magnus Carlsen à David Navara dans le tournoi de Wijk aan Zee 2007, Carlsen rata une occasion de gain grâce à une attaque à la découverte.

Dans la position du diagramme suivant, les Noirs viennent de jouer 31…g5 ??, qui laisse leur Dame non-protégée. Voyez-vous comment Carlsen aurait pu en profiter ?

8/pp1r2kp/3P4/1QP2qp1/P7/6BP/6P1/6K1 w - - 0 32

[Result "*"] [SetUp "1"] [FEN "8/pp1r2kp/3P4/1QP2qp1/P7/6BP/6P1/6K1 w - - 0 32"] 32. a5 $4 (Carlsen rate l’occasion de gagner par l’attaque à la découverte 32. c6 qui conduit à une position gagnante après Qxb5 33. axb5 bxc6 34. bxc6) *

L’échec à la découverte

Un échec à la découverte est un échec effectué non pas par la pièce qui bouge, mais par une pièce (Fou, Tour ou Dame) située derrière celle-ci. Puisque le joueur en échec doit obligatoirement parer cet échec, la pièce qui bouge peut être utilisée de différentes façons:

faire elle-même échec (on parle alors d’un échec double)

prendre une pièce ou un pion sans craindre d’être reprise

attaquer une pièce plus importante qu’elle pourra prendre au coup suivant

Dans la partie Levon Babujian – Luka Paichadze jouée lors de la coupe Poti Aleksandria en 2013, les Noirs profitent de l’échec à la découverte sur le Roi blanc de façon astucieuse:

2r3r1/p6k/1p2q2p/4Bp2/2bP3P/Q4P2/P7/2KR2R1 b - - 0 29

5 Amazing Instagram Feed Ideas with Bonus Tips

Looking for some Instagram feed ideas? Your Instagram feed is the first thing people look at when visiting your profile, and as in life, you want to make a good impression.

As Instagram matures, simply having amazing edited photos isn’t enough: now you have to have a cute feed too! And it’s not as easy as it looks.

To help you make your feed the best it can be, follow our feed guide and tips below to take your new Instagram feed ideas from good to amazing:

1. Choose an Instagram Aesthetic

You may have heard that your Instagram feed needs to have a certain theme to it: food, fashion, travel, etc. That doesn’t sound very fun though, does it? You shouldn’t have to limit yourself to only showcasing one part of your life in order to be successful on Instagram. Instead of choosing a theme for your Instagram, settle on a common aesthetic that weaves through all of your photos. Choosing an aesthetic gives you more freedom with your feed, because as long as your photo fits the “vibe” of your Instagram, you can post about pretty much anything!

You could choose a bright, golden, moody, dark, or colorful aesthetic for your Instagram feed. To choose your own, scroll through your existing feed and see what aesthetic your favourite photos have in common. Photographer Caroline Lee of @teamwoodnote curates bold and colorful photos for her Instagram feed, which works for every aspect of her photography; from editorial shoots to wedding photography, and even her selfies and food photos.

2. Use Similar Filters to Keep Your Instagram Feed Layout Consistent

To help you curate Instagram and have your feed flow naturally, you should have a consistent approach to editing your photos. This doesn’t mean you have to choose one filter and one filter only, but limiting yourself to a few will help you stick to your chosen aesthetic. Apps like A Color Story are great for bright feeds, whereas VSCO Cam is great for moodier or golden feeds. Woodworker and Instagrammer Aleksandra Zee (@aleksandrazee) has a golden Instagram aesthetic, and edits her photos to give them a warm tone. She posts a variety of subjects, like her dog, beach trips, selfies, and her woodworking projects that are for sale. Because she uses a similar editing process, not only do the individual photos look great, but her feed as a whole tells a larger story.

If you don’t want to be as selective when it comes to editing, but you still want your feed to have it’s own “look,” take some tips from the Instagram queen herself, @KimKardashian. Kim doesn’t stick to a specific aesthetic for her feed and posts, and with over 60 million followers, who’s to stop her? But to make her Instagram feed look as gorgeous as her selfies, she uses a little bit of Instagram’s “Aden” filter on top of every photo to add a warm and purplish hue.

Even if you just add a touch of the same filter each time you post, it can make your brand and Instagram feed seem more cohesive. Compare this to when Kim wasn’t adding the filter every time, and you can see a dramatic difference in how well the feed flows.

3. Don’t Let Your Instagram Feed Get Out of Order

Take a step back from posting one photo, and look at your Instagram feed as a whole: how do all of your photos fit together? The prettiest feeds have a good variety of subjects that are evenly spaced out. Artist Melody Hansen (@themelodyh) has a highly curated Instagram feed, and she evenly distributes a mix of selfies, nature, and her artwork. You’ll notice that she doesn’t post two selfies or two drawings in a row, and she posts complementary tones, which really brings the feed together.

One of the hardest parts of making your Instagram feed look amazing is figuring out how to make all your individual photos look good beside each other. Some Instagrammers will post a photo, and if they don’t like how it fits with their feed, will either quickly delete it, or wait until the next day to delete it in order to keep their feed consistent. The best way to curate an Instagram feed is to preview it in grid format beforehand. This way, you can move your photos around to create the best vibe, or swap out different photos of the same subject to see what works best.

Later’s Visual Instagram Planner makes it super easy to plan and design the perfect Instagram feed. Simply drag & drop your photos onto our visual Instagram planner, re-arrange them to see how they’ll look in your feed, and click “Save Changes” to schedule them!

Tip: space out photo subjects by either one or three photos, not two, to avoid having two selfies or two food shots on top of each other in a column.

4. Good Instagram Feeds only Post Photos that Fit

In addition to editing photos to your chosen aesthetic, you also have to be selective when it comes to choosing which photos you are going to post. For example, a busy photo is going to seem out of place for a minimalist feed, no matter how you edit it. If all your photos are bright and full of sunshine, a dark evening photo just won’t work.

That being said, sometimes a really amazing moment happens and you want to share it with the world (aka Instagram). You might have a photo that you really want to post, but no matter how many times you edit it, it just doesn’t fit with your feed. In this case, you have two options: post it anyway, or muster all your self-control to not post it. If it’s your personal Instagram feed, a few concessions now and then are okay – it’s just Instagram! But if you’re using Instagram for your brand, one photo that doesn’t fit with your aesthetic is all it takes to lose followers forever. Don’t risk diluting your hard-earned Instagram brand for one photo, and instead choose to share that photo on Facebook or Twitter instead.

Once you’ve found the perfect photos for your feed, you can quickly Quick Schedule your Instagram posts with Later! Simply select your ideal times to post, choose your photos and videos, and just drag & drop onto the calendar to bulk schedule multiple Instagram posts at once.

One last tip: if you have a photo you love that just doesn’t fit, try making it black and white to have it flow with your feed better.

5. Instagram Feed Inspiration Takes Time and Planning

If you really want to level up your Instagram feed, the best thing you can do is set aside time to spend on it. Long gone are the days when Instagram was actually “instant,” and these days it’s more efficient to work on your Instagram in chunks of time. Lots of popular Instagrammers will dedicate one or two days a week to shoot and edit content for their Instagram feeds, and then publish those photos throughout the week.

Fashion Instagrammer Claire Teixeira from @theworkinggirl will take one outfit and photograph it two or three different ways — as a flat lay, as a whole outfit, and then a detailed shot, for example. She then posts them over a span of several days, adding in an extra photo here or there.

Scheduling your posts makes managing your Instagram throughout the week a breeze. By taking the time to plan out and curate Instagram content, you can post more consistently and schedule your posts for optimal times, which will increase your exposure and help grow your followers. With Later’s media library, you can upload all your posts and then easily schedule them for the rest of the week!
