'Momentum' is hard to define in cricket, but you know when you have it: That feeling of being on top of the game.

Smart players and coaches know how to control momentum: to be in charge of the flow and pace of the game. They understand when to ride this wave of success. They also know when to take action to get it back if it starts to slip away.

Spinners have found a renaissance in the Twenty20 game. The slower pace and wider potential for variety makes the ball harder to hit.

However, when a spinner does come on, many batsmen decide it's time to go for the big hits.

What tactics can you use as a spinner to limit the damage someone can do?

The worst batsman in the team is placed last in the order. Why would anyone do anything different?

I think there are circumstances where you would consider putting a better batsman at 11, and the chance to do so happens more often than you might think.

Twenty20 bowling is about limiting scoring by stopping the batsman playing his best shots.

Unlike longer formats this is not done through bowling a predictable line and length. This approach simply gives the batsman the chance to play his premeditated shots or free her arms and hit you all over the park. The solution is to have a range of different lines, lengths and angles combined with changes of pace.

As I write this the group stages of the World Twenty20 2009 have just finished. What lessons can club players take from the tournament so far?

It's certainly been dramatic: The last ball thrilling opener, Australia crashing out, amazing batting and spinner's domination. Among the chaos of six hitting and stumps flying there have been some lessons all cricketers who play the shorter format to follow.

In my opinion, the formula for winning a T20 or 50 over game is the same for most cricket teams (i.e. everyone playing below the 1st Class level).

A good cricket team is made up of different personalities and skills. Helping make the right blend of these elements starts with the captain and the team he or she selects.

Selection at club or school level is different from the top tiers. There is very little concern about picking the extra batsman and the like. In fact for many captains the only selection issue is whether you can raise 10 other players!

There are basically two ways to bowl a cricket ball.

The first is trying for the 'magic' ball. Perhaps it's the yorker that swings in fast and late, or the off spinner that drifts away before turning and bouncing. They are unplayable and make the batsman look helpless against your superior skills.

The former Middlesex bowler Simon Hughes certainly thinks so. He uniquely explains the rise of Graeme Swann from bad boy to first choice England spinner. Swann doesn't get his wickets through vicious turn and bounce. He doesn't get them through a mysterious doosra or carom ball.

Low scoring games are an intense mental challenge for players. It's the side who can hold their nerve that come out victors.

It's about a combination of attitude, tactics and effort.
