What makes Bhuvneshwar a threat?
On the face of it Bhuvneshwar Kumar has no quality that's likely to catch a layman's fancy. But face him with a bat in hand and you'll know his worth

Bhuvneshwar's approach to the crease reminds me of the great Shaun Pollock. Just like the South African, he gets really close to the stumps. The closer the bowler gets to the stumps, the tougher it gets for the batsman, for there are less pronounced angles to play with. The line of the ball is always in line with the stumps, which means the batsman has no choice but to play at most deliveries.
The best way to swing the ball in the air and to get lateral movement off the deck is to release the ball with the seam bolt upright. The more still the seam is in the air, the better the chances that it will not only deviate in the air but also hit the pitch on the seam and dart around. While it sounds quite simple in theory, it's extremely difficult to execute, for to keep the seam upright at the point of release, the wrist needs to be strong and also right behind the ball. That's what Bhuvneshwar has; his immense control over his wrist allows him to not only release the ball with the seam upright but also allows him to make subtle changes (like pointing it towards slips or fine leg) by tilting his wrist to move the ball both ways. If you're able to do that with control, you will trouble the best batsmen.
Bhuvneshwar has neither the pace of Umesh Yadav nor the bounce of Ishant Sharma. What he does have is an understanding of the importance of hitting the right length time and again. He realises that since his strength is movement, he needs to pitch it a lot fuller, for the longer the ball stays in the air, the better the chances of it moving. Also, it's a length that batsmen, especially openers, hate in the early part of an innings. Bhuvneshwar is not afraid of being hit through the line and that quality allows him to find edges often, for it isn't possible for batsmen to always keep middling the ball when it is swinging.
