Be bold, decisive: How NZ should play Indian spin
A quick course on playing spin in the subcontinent

You must look to attack the spinner early in the innings to force him to push back his field, which will help you rotate the strike • AFP
Read the ball from the hand, not from the pitch, because it will give you a little more time to react. Use both feet to either get to the pitch of the ball with a long forward stride or to go deep inside the crease to shorten the length. Spinners are at their most dangerous when the batsman refuses to get to the pitch of the ball to smother the lateral movement off the surface. That's what New Zealand did in Hyderabad. Most of their batsmen were rooted to the crease and offered unconvincing forward prods to everything that was pitched up, in hope that the ball would find the middle of the bat. Their shots lacked conviction and resulted in many bat-pad catches. Some New Zealand batsmen started shuffling to counter the spin, but little did they realise that sideways movement within the crease can only be effective against fast bowlers because it helps you play in the second line. Only a decisive forward-and-backward movement can save the day against spinners. In England, Hashim Amla did that beautifully against Graeme Swann.
On turning pitches, you must be aggressive, for no matter how good your defensive technique, the odd ball will turn and jump unexpectedly to abruptly end your stay. If you only concentrate on defending, as New Zealand did in the second innings, the spinners won't feel threatened and will continue to flight the ball. To extract optimum spin and bounce off the surface, spinners must give the ball some air. This becomes easier if the batsman has gone into a shell. All quality players of spin take the aerial route really early in the innings, because it forces the bowler to not only push the fielders back but to also cut down on flighting the ball. Once the fielders are pushed back, batsmen find it easier to rotate the strike, and the moment a spinner starts bowling flatter, he plays into your hands. MS Dhoni did it efficiently against Jeetan Patel the moment he walked in to bat in Hyderabad.
Since spinners bowl a lot slower than the quicks, it's tempting to reach for the ball. But if you're defending, you must resist the temptation and allow the ball to come to you, as you would when facing a fast bowler. Once you have allowed the ball to come to you, play it as delicately as possible with soft hands. Let the top hand remain firm while barely holding the bat with the bottom hand.
