Spin bowling is the most subtle art in cricket and 
                             it is the most psychologically demanding. The 
                             margin of error is less, as the pace of the 
                             delivery is slow. However, the slower pace also 
                             ensures that slow bowlers do not stray in line and 
                             length as much as fast bowlers. To be a successful 
                             spin bowler, one has to relax and maintain muscle 
                             control. The spinner should not push the ball 
                             through, but deceive the batsman by the flight. 
                             This might sounf odd, but spin bowlers should work 
                             on their relaxation and self-confidence, to achieve 
                             benefits like line and length, spin and flight, 
                             etc!.
                               
                                                                                                        
                                                                                                        
                             Important bowling skills for spinners are the 
                             bowling action and the ability to turn and flight 
                             the ball. The spinner has to plan well in advance 
                             to meet the challenges and adopt the same according 
                             to the situation. Say, you decide not to allow Sachin Tendulkar to paddle-sweep, but he manages to 
                             do so. You should then change your plan and try and 
                             bowl further outside the off-stump and see what he 
                             does. Thinking like this will make you a better 
                             bowler. 
                             
                             The 
                             quality spinner will study the batsman's stance, 
                             grip and height and accordingly adjust his line and 
                             length.
                             
                             Vinoo Mankad, one of the greatest left-arm spinners 
                             of all time, was a great exponent of the art of 
                             spin bowling. I had the pleasure and privilege to 
                             keep wickets to him. I have seen his subtle 
                             variations from close quarters.
                             
 
 
                              
                             
                            
                             
                             On other occasions, he would bowl three deliveries 
                             with varying degrees of flight but a similar 
                             length. To achieve Vinoobhai's mastery, the bowler 
                             should practise for hours in the nets on his own, 
                             or with only a wicketkeeper, under the able 
                             guidance of his coach.
                             
                             The slow bowler has to make maximum use of the 
                             bowling crease. He should try to deliver the ball 
                             from different angles of the crease to vary his 
                             deliveries in their flight and line. He should mix 
                             his deliveries, bowling some from close to the 
                             stumps, others away from the stumps and some from 
                             the corner of the crease as well.
                             
                             The slow bowler should adjust his flight keeping in 
                             mind the end from which he is operating. The 'wind 
                             factor' will come into play here - whether he is 
                             bowling into the wind or with it, or if it is 
                             blowing sideways. The leg-spinner and left-arm 
                             spinner should bowl against the wind.
                            
                                                                                                        
                                                                                                        
                           
                              In fact, a bowler who gives the ball a lot of air 
                             should bowl against the wind. Spinners should also 
                             observe the condition of the pitch. On a flat 
                             track, the bowler should give the ball more air, 
                             and on a turner, he should mix his flight with 
                             deliveries of a lower trajectory. Wickets in India 
                             tend to crack as the game progresses, and more turn 
                             can be extracted by pushing the ball flatter. Spin 
                             bowlers should also take advantage of the footmarks 
                             created by the fast bowlers at the opposite end and 
                             bowl the occasional spell from around the wicket. 
                             Shane Warne of Australia and our own Anil Kumble 
                             have succeeded in getting wickets or keeping down 
                             the runs from an 'around the wicket' line.
                             
                             Successful spin bowlers have always 'hunted' in 
                             pairs like fast bowlers. Earlier, Vinoo Mankad and 
                             Subhash Gupte did a great job for India. Anil 
                             Kumble and Harbhajan Singh have the talent and 
                             wherewithal to achieve something similar.
                                 
 
                             
                             
                             If a batsman is playing forward, the spinner should 
                             bowl to make him play on the back foot, and 
                             vice-versa. If the batsman is playing across the 
                             line, the bowler must capitalise on this weakness.
                             
                             More often, matches are won because of the bowler 
                             rather than a batsman. I say this because that is 
                             what I have seen happening for years and years, 
                             from my position behind the wickets at the 
                             batsman's end.
