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 "xR" to satisfy the ascending chain condition, and the latter only examines the poset of ideals of the form "Rx". A theorem of Hyman Bass in now known as "Bass' Theorem P" showed that the "descending chain condition" on principal "left" ideals of a ring "R" is equivalent to "R" being a "right" perfect ring. D. Jonah showed in that there is a side-switching connection between the ACCP and perfect rings. It was shown that if "R" is right perfect (satisfies right DCCP), then "R" satisfies the left ACCP, and symmetrically, if "R" is left perfect (satisfies left DCCP), then
