When you get say, 15 overs into a test match, get your best spinner and set the field to aggresive 2. Then bowl all of your balls at a different pace each time and also make sure that they all go on a full length around offstump. The batsmen will play forward defensive and most of the time he will chip the ball up to the men who are standing right by the crease. I used this against Australia and bowled them out for 46. A very good tactic to use once you get used to it. Practice makes perfect!
