Question: A short corner starts with how many defenders, including the keeper?
About the article "Field hockey", section "Penalty corner".

Candidate passages:
The short or penalty corner is awarded: 
 for an offence by a defender in the circle which does not prevent the probable scoring of a goal
 for an intentional offence in the circle by a defender against an opponent who does not have possession of the ball or an opportunity to play the ball
 for an intentional offence by a defender outside the circle but within the 23-metre area they are defending
 for intentionally playing the ball over the back-line by a defender
 when the ball becomes lodged in a player's clothing or equipment while in the circle they are defending
Short corners begin with five defenders (usually including the keeper) positioned behind the back line and at least 5 m from the 'insert' position of the ball.
All other players in the defending team must be beyond the centre line, that is not in their 'own' half of the pitch, until the ball is in play.
Attacking players begin the play standing outside the scoring circle, except for one attacker who starts the corner by playing the ball from a mark 10 m either side of the goal (the circle has a 14.63 m radius).
This player puts the ball into play by pushing or hitting the ball to the other attackers outside the circle; the ball must pass outside the circle and then put back into the circle before the attackers may make a shot at the goal from which a goal can be scored.
FIH rules do not forbid a shot at goal before the ball leaves the circle after being 'inserted', nor is a shot at the goal from outside the circle prohibited, but a goal cannot be scored at all if the ball has not gone out of the circle and cannot be scored from a shot from outside the circle if it is not again played by an attacking player before it enters the goal.
For safety reasons, the first shot of a penalty corner must not exceed 460 mm high (the height of the "backboard" of the goal) at the point it crosses the goal line if it is hit.
However, if the ball is deemed to be below backboard height, the ball can be subsequently deflected above this height by another player (defender or attacker), providing that this deflection does not lead to danger.
Note that the "Slap" stroke (a sweeping motion towards the ball, where the stick is kept on or close to the ground when striking the ball) is classed as a hit, and so the first shot at goal must be below backboard height for this type of shot also.
If the first shot at goal in a short corner situation is a push, flick or scoop, in particular the "drag flick" (which has become popular at international and national league standards), the shot is permitted to rise above the height of the backboard, as long as the shot is not deemed dangerous to any opponent.
This form of shooting was developed because it is not height restricted in the same way as the first hit shot at the goal and players with good technique are able to drag-flick with as much power as many others can hit a ball.

"Keeper of the Seven Keys Part 2" is the third studio album by German power metal band Helloween, released in 1988.
The album capitalized on the success of "Keeper of the Seven Keys Part 1" and picks up where it left off.
Michael Weikath starts to come back into the picture as one of the premier songwriters in the band writing some of the most popular tracks to date.
The album is one of the most influential power metal albums of all time, and many say that it really shows off the band's talent during this period.
Success bloomed all over Europe, Asia and even the United States.
The album went gold in Germany and reached #108 in the US.
The album starts off with a short instrumental "Invitation".
The second track, "Eagle Fly Free" became a trademark of the band after this album.
"You Always Walk Alone" is a song written by Michael Kiske, then a new member of the band.
"Rise And Fall" is more a classic metal-sounding song played at breakneck speed and comical lyrics.
"We Got The Right" is the sole power ballad of the album.
"Save Us'" and "March of Time" were written by founder Kai Hansen.
The album contains two singles, which are "Dr. Stein" and "I Want Out".
"Dr. Stein" has a very long and moody solo, played with a blues tinge, very unlike other solos in the album as well as an organ solo.
"I Want Out" remains one of the band's most popular songs, and has been covered by Gamma Ray, HammerFall, LORD and Sonata Arctica.
This song was written by Kai Hansen, and it's rumored to have to do with how he felt about Helloween, that maybe the band wasn't his anymore.
The title track is the longest song of the album.
Michael Weikath's "Eagle Fly Free", one of the well known songs of the album has also covered, as Kai Hansen's "I Want Out", by bands like Vision Divine, and Bassinvaders.
The album was re-released in 1993 as a double-CD with Keeper of the Seven Keys Part 1.
It included the bonus tracks "Don't Run for Cover", "Living Ain't No Crime", and "Savage". 
The lap starts with a short sprint up Boulevard Albert 1er, to the tight "St.
Devote" corner.
This is a nearly 90 degree right-hand bend usually taken in first or second gear.
This corner has seen many first lap accidents, although these are less common since the removal of the mini roundabout on the apex of the corner before the 2003 event, making the entrance to the corner wider.
The cars then head uphill along Avenue d'Ostende, before changing down for the long left-hander at "Massenet".
Out of Massenet, the cars drive past the famous casino before quickly reaching the aptly named "Casino Square".
The cars snake down Avenue des Beaux Arts, the next short straight, avoiding an enormous bump on the left of the track, a reminder of the unique nature of the circuit.
This leads to the tight "Mirabeau" corner, which is followed by a short downhill burst to the even tighter "Grand Hotel Hairpin" (more commonly known by its former name the "Loews Hairpin", and before that as the "Station Hairpin").
It is a corner which has been used for many overtaking manoeuvres in the past.
However it would be almost physically impossible for two modern F1 cars to go round side by side, as the drivers must use full steering lock to get around.
It is so tight that many Formula 1 teams must redesign their steering and suspension specifically to negotiate this corner.
After the hairpin, the cars head downhill again to a double right-hander called "Portier" before heading into the famous tunnel, a unique feature of a Formula One circuit.
(Until 2009 only one other circuit, Detroit USA in 1982–88, featured a tunnel, but the F1 series now includes racing at the Yas Marina Circuit in Abu Dhabi, which presents a shorter tunnel at the exit of the pit lane.)
As well as the change of light making visibility poor, a car can lose 20–30% of its downforce due to the unique aerodynamic properties of the tunnel.
Out of the tunnel, the cars have to brake hard for a tight left-right-left chicane.
This has been the scene of several large accidents, including that of Karl Wendlinger in 1994, Jenson Button in 2003 and Sergio Pérez in 2011.
The chicane is generally the only place on the circuit where overtaking can be attempted.
There is a short straight to "Tabac", a tight fourth gear corner which is taken at about 195 km/h (120 mph).
Accelerating up to 225 km/h (140 mph), the cars reach "Piscine", a fast left-right followed by a slower right-left chicane which takes the cars past the Rainier III Nautical Stadium, its swimming pool gives its name to the corner.
Following "Piscine", there is a short straight followed by heavy braking for a quick left which is immediately followed by the tight 135 degree right-hander called "La Rascasse".
This is another corner which requires full steering lock; it will be remembered for a long time as the location of one of the most suspicious manoeuvres in recent Formula One history after the 2006 season when Michael Schumacher appeared to deliberately stop his car in qualifying so as to prevent Fernando Alonso and Mark Webber – who were both following and were on flying laps – from out-qualifying him.
The Rascasse takes the cars into a short straight that precedes the final corner, "Virage Antony Noghes".
Named after the organiser of the first Monaco Grand Prix, the corner is a tight right-hander which brings the cars back onto the start-finish straight, and across the line to start a new lap.
