Kevin Pietersen doesn’t have a weakness against left-arm spin. Not directly anyway. Kevin Pietersen’s weakness is that sometimes he thinks he could travel to the moon without a vehicle or oxygen.
All players have a confidence range. Sometimes they’re up, sometimes they’re down, but the extremes aren’t the same for all players.
For example, you want Andrew Strauss to be as confident as possible, because when he’s nervy, he gets out. Kevin Pietersen’s optimum level of confidence is in the mid to low end of his range. Kevin Pietersen is at his most vulnerable when he’s on 185 and he’s just switch-hit a six or when a left-arm spinner who doesn’t turn it much comes on to bowl.
When faced with Paul Harris, Ryan Hinds or Yuvraj Singh, KP assumes that he’ll middle every ball. As a consequence, he doesn’t consider playing across the line at a ball delivered straight at the stumps is in any way dangerous.
At our most confident, we feel like there’s a healthy chance that we won’t walk into a door frame. We can never aim much higher than that.
