Hello everyone. You might wonder why we're so obsessed over short castling. Well, here are the reasons.1. Short castling is safer.Short castling is safer in general. For example, in this position: Black's king is safer despite the pawns on the kingside being fairly advanced. In this variation of the Dutch Defense, one of Black's main ideas is to go for a kingside attack - the king is in fat very safe. Now let's compare this to an unsafe queenside castle: As you can see, the Black king is vulnerable to attack due to the open holes on the c-file, and White can easily take advantage. Meanwhile, White's king, castled short on the opposite side of the board, is safe from attack - any attack can easily be repelled by h3, g3, or if needed, f3 (or f4). 2. Kingside castling works best with fianchettoed bishops.Many openings (most notably King's Indian systems) see king's bishops fianchettoed on a powerful position on g2 or g7, breathing down the important long diagonal, followed by O-O. The reason this is is that the bishop not only perfectly fits to defend the light/dark squares around the king, it also shields the king should the pawn cover ever come off. In long castling, the bishop is not only not perfectly aligned, it doesn't defend the d2/d7 and c2/c7 squares, which are among the weakest should the pawn cover ever come off. Additionally, a bishop on b2/b7 takes away that square from the king, which is usually moved somewhere on those squares to defend the a-pawn (we'll talk more about this later). Here are some examples: Black's dark squared bishop ties down all potential weaknesses of the dark squares in Black's kingside while also breathing fire down the a1-h8 diagonal. This extremely powerful bishop works in tandem with the king to begin a strong attack in many King's Indian Defense variations where Black goes for a pawn storm on the kingside. The bishop and knight provide a shield to the king and prepare to remove the pawn cover. As you can see, White's queen is basically trapped. While both sides have their pawn cover gone, Black's king is definitely more secure due to the bishops and knight. Should the queen move off the diagonal, the light-squared bishop takes control of the c2 and b1 squares right next to the king. White's queenside attack and bishop are not doing anything, while Black is prepared to rip open the kingside of White.3. Activation of the rookIn many e4 openings, the d-pawn is rarely moved while the e-pawn becomes a prized commodity. 1.e4 is by far the most common opening, and there's a good chance most of you reading this are e4 players. Even if you're not, you will encounter 1.e4 and reply with 1...e5 sometime in your chess career. Why don't you want to castle to the side that supports this opening the most? And the appeal of short castling is not limited to e4 - many systems in d4 openings call for an e4/e5 pawn break (London, Dutch, and others come to mind). Short castling allows the rook to move immediately to e1/e8 supporting these dreams. But you might say "But if the square is empty, long castling does that too!" Well, you're right, but what about the f-file? Many positions call for an f4/f5 pawn break, taking space on the kingside and beginning a kingside attack. Why wouldn't you want your rook to support that? Additionally, there is an opportunity for the rook to shine in other common openings - especially in one I play very often. Look at how powerful that rook would be after the knight moves! Many opponents take the knight, further fueling the fire that is the f1-rook. After the knight is unpinned via queen development, a three-pronged attack (via Ng5) on f7 will be underway. Even if Black takes action to stop this, the pressure down the f-file will, if you make sure of it, impossible to shrug aside any longer. Is there anything even comparable in queenside castling?4. Kingside castling takes one move less.Kingside castling only requires you to move the bishop and knight, as seen in the Italian Game, one of the most commonly played openings (1. e4 e5 2. Nf3 Nc6 3. Bc4) as well as other openings (Ruy Lopez, Bishop's Opening, Petrov's Defense variations, etc.) The kingside pieces are among the first to be developed as opposed to the queenside pieces, so why not use this opportunity and castle right after the pieces are out? Queenside castling takes an extra move - moving the queen, and in most cases it's not obvious where the queen belongs until more pieces are out and the middlegame position begins to take shape. Do you really want to wait until then to castle?No! So make use of the saving of a tempo and castle kingside!5. Queenside castling requires the defense of the a-pawn.If you do ever castle queenside, you'll notice the a-pawn is undefended. This can become a problem especially in the endgame, where there might not be a c3-knight to defend the a-pawn. Many games have been lost due to the hanging of this pawn. It's not just a pawn - it's the beginning of the highway to your king and your position! A rook or queen on a2/a7 while you're castled queenside would not only lose you a pawn - it would absolutely wreck your position and threaten mate! The only way to prevent this is to waste a tempo playing the seemingly useless move Kb1/Kb8 or a3/a6 (or a4/a5). Do you really want to give your opponent an extra move to develop or prepare an attack?Kingside castling protects all of the pawns involved and there is no roadway into your position. These are just some of the reasons that short/kingside castling appeals to us, and why it should appeal to you too!
