days, a lead of at least 100 runs. In a one-day match, a lead of at least 75 runs. When the start of a match is delayed by one or more full days, e.g., due to bad weather, the score lead required to enforce the follow-on is reduced accordingly. However, when a match duration is shortened after it has started, the score lead required to enforce the follow-on remains unchanged. Enforcement The follow-on is not automatic; the captain of the leading team decides whether to enforce it. Conventional theory suggests the follow-on is almost always enforced. In his classic text The Art of Captaincy, Mike Brearley deals with the issue in a single paragraph, and finds the advantages overwhelming. The main reason to enforce the follow-on is to prevent a draw. Batting last, the chasing side can bat cautiously and use up time to draw the match rather than lose, and the follow-on gives them more time, making that strategy more difficult. Enforcing the follow-on can also increase the pressure on the chasing team, since they have already posted an inferior score, and the state of the pitch often deteriorates as a match progresses. However, there are several reasons for not enforcing the follow-on: Most simply, it is tiring for bowlers to bowl for two consecutive innings, and it can be more difficult to dismiss a team in their second innings than it was in their first innings. During the first test of the 1958 series between Pakistan and West Indies on 17–23 January, West Indies batting first declared at 579/9 and Pakistan replied with 106 all out. After Pakistan was asked to follow-on on the third day of the six-day match, Mohammed Hanif held his ground for 970 minutes, scoring 337 runs, forcing a draw. Declining to enforce the follow-on reduces the defending team's probability of losing. Already with a substantial lead in the first innings, the defending team can score enough runs and/or use up enough time to give the chasing team no chance of victory. This does increase the probability of a drawn result, but it can also demotivate the chasing team who have nothing to play for. It is usually a disadvantage to bat last, when the pitch has deteriorated and favours spin bowling. In recent years there has perhaps been a trend against enforcing the follow-on in Test cricket: former England captain Andrew Strauss on
