The Modern Defense (also known as the Robatsch Defence after Karl Robatsch) is a hypermodern chess opening in which Black allows White to occupy the center with pawns on d4 and e4, then proceeds to attack and undermine this "ideal" center without attempting to occupy it. The Modern Defense usually starts with the opening moves: 1. e4 g6
For example, factory and aftermarket receivers using the Remington 700 footprint are produced with various types of action threads, all with a 26.99 mm (1 + 1 ⁄ 16 in) diameter, but with a pitch of either a 1.588 mm (16 TPI, Remington standard), 1.411 mm (18 TPI) or 1.270 mm (20 TPI, Savage standard).
The latter promises a tactical melee, with a common line being 6.Bb5+ Bd7 7.e5 Ng4 8.e6 (8.h3 or 8.Bxd7+ are other possibilities) 8...fxe6, which was thought bad, until Yasser Seirawan played the move against Gyula Sax in 1988 [9] (8...Bxb5 is the alternative, if Black does not want the forced draw in the main line), continuing 9.Ng5 Bxb5!

where is the tap drill size, is the major diameter of the tap (e.g., 3 ⁄ 8 in for a 3 ⁄ 8-16 tap), and / is the thread pitch (1 ⁄ 16 inch in the case of a 3 ⁄ 8-16 tap). For a 3 ⁄ 8-16 tap, the above formula would produce 5 ⁄ 16, which is the correct tap drill diameter. The above formula ultimately results in an approximate 75% thread.
An interrupted screw or interrupted thread is a mechanical device typically used in the breech of artillery guns. It is believed to have been invented in 1845. [1] The system has also been used to close other devices, including the joint between helmet (bonnet) and breastplate (corselet) of standard diving suit helmets, and the locks of diving ...
According to Jim Bickford, [1] one of the characteristics of this defense is the "cork-screw" maneuver the knight makes by traveling to the second rank via f6 and h5.
