Batting (cricket) square cut. The difference between the cut and the square drive is the height of the ball at contact: the cut is played to a ball bouncing waist high or above with the batsman standing tall, whereas the square drive is played to a wide ball of shin height with the batsman bending his knees and crouching low to make contact. A pull is a cross-batted shot played to a ball bouncing around waist height by swinging the bat in a horizontal arc in front of the body, "pulling" it around to the leg side towards mid-wicket or square leg.
Ascending chain condition on principal ideals Ascending chain condition on principal ideals In abstract algebra, the ascending chain condition can be applied to the posets of principal left, principal right, or principal two-sided ideals of a ring, partially ordered by inclusion. The ascending chain condition on principal ideals (abbreviated to ACCP) is satisfied if there is no infinite strictly ascending chain of principal ideals of the given type (left/right/two-sided) in the ring, or said another way, every ascending chain is eventually constant. The counterpart descending chain condition may also be applied to these posets, however there is currently no need for the terminology "DCCP" since such
