This week's winner of the Cricket Show podcast question competition is AB. He wins a free coaching course from PitchVision Academy.

The winning question was:

"If there is a leg glance, why is there not an off glance? Do you think the way we traditionally coach batting as a discrete set of separately named shots is a help or a hindrance when it comes to producing batsmen with a coherent skill set and flexible game plans?"

Listen to the panels answer to his question here.

The doosra seems to have almost become a standard delivery for off-spinners these days. If a new hot spinner breaks into the scene, you are almost guaranteed that he will be able to bowl a doosra.

Thing is, the doosra is devilishly tough to bowl. It's not for everyone. The good news is that it is not needed to become a top international spin bowler.

However, variations - used well - are as effective as ever.

Here is a really simple cricket practice hack: Use two net bays instead of one.

This is because it opens out the net which gives the batsman a more realistic feel of batting in the middle. Nets are typically made more artificial by the feeling on being enclosed in the net. It's safe, almost womb-like in there.

Opening out the net suddenly presents the batsman with a more realistic feel of being "in the open". It adds pressure.

I was terrible at science when at school. I couldn't see the relevance of it and found every way possible of avoiding lessons. However, the bit that I did like was experimentation.

The fact that I was allowed to try things, to see if they work or don’t work was great and I have taken that on into my coaching.

Experiment with these opposites with your individual players and see what impact they have on their performance/experience when catching and batting.
