Form I: Shii-Cho (Powerstaark)

Shii-Cho also known as 'the way of the Sarlacc' or 'the determination form' was the oldest and most simple style of lightsaber combat.

Despite or rather because of its simplicity Shii-Cho is an effective combat form though it was better against blaster wielding opponents than lightsaber wielding ones. However a master of Shii-Cho could be a formidable opponent against a lightsaber wielding enemy too. Because of its simplicity almost every if not every Jedi was trained in the style as younglings. Count Dooku believed that Shii-Cho swordplay was 'clumsy but relentlessly dogged' and users were known to try to cut off their opponents escape and drive them into a corner

Stance and maneuvers
The stance of Shii-Cho was to hold the lightsaber horizontally across the shoulder. From there the user could swing their lightsaber down or around at their opponent. A commonly used Shii-Cho maneuver was called the 'Sarlacc Sweep' which was a wide, sweeping blow designed to take down several enemies at once.

Shii-Cho practitioners would often attempt to disarm their opponents and therefore used a technique called the 'Disarming Slash' where they would attempt to rip the opponents weapon out of their hands with a powerful blow. However this techniques was almost useless against Makashi practitioners.

Practitioners
Kit Fisto was one of the most well known masters of Shii-Cho and his mastery of the style made him one of the Jedi Order's finest swordsmen. He was able to combine his Shii-Cho mastery with Jar'Kai despite lack of formal training in the dual lightsaber form. Saesee Tiin was also a master of Shii-Cho. Oppo Rancisis also mastered Shii-Cho and used it in a personalized mix with Djem So.

Grand Master Yoda was also a master of Shii-Cho teaching it to numerous Jedi Younglings over the long centuries of his life. However he rarely actually used the style prefering to rely on Ataru and Soresu. Jedi Masters Sora Bulq and Cin Drallig were both masters of Shii-Cho and like Yoda they trained younglings to use it during their Jedi careers.

Even Piell also practiced Shii-Cho in addition to the other lightsaber forms. Master Fisto's former Padawan Nahdar Vebb was also a practitioner of Shii-Cho but he was no match for the deadly General Grievous.

Anakin Skywalker and Obi-Wan Kenobi had at least basic knowledge of Shii-Cho using it against Count Dooku on the Invisible Hand in a successful attempt to lull the Sith Lord into a false sense of security. After his turn to the Dark side and his defeat to Obi-Wan on Mustifar Darth Vader continued putting elements of Shii-Cho into his variant of Djem So.
