Well, here are my findings:
1. Regardless of pitches, your first 10 runs are crucial to get. In t20s, just stick to the basics for atleast 6-7 deliveries. Atleast raise your confidence meter by 10% before cutting loose. Else, your timing and footwork will be awful.
2. All soft pitches are difficult to bat on. In whites, batting last is horrible. I had scored 21 of 69 before being bamboozled. In t20s, i only try to maintain a run a ball approach.
3. Quite surprisingly, i found all green decks are quite easy to bat on. I did adjusted edge couple of times but that's on me.
4. Spinners are indeed a challenge. I've tried whacking them from the get go, also tried defending heavily, but they are painful. What i found is, playing aggressive grounded shots to them often comes handy. Else, just a flicker through leg. Anything on the offside, i either defend or leave. Sometimes, i execute a precision shot for a sneaky single.
5. Hard surfaces are bouncy. One wrong timing can send you packing. I always approach the pacers on the backfoot here, mostly. My favourite area is over the mid off and straight. Spinners even bounce the balls rather higher here. I tend to negotiate them with basic grounded stroke with front foot. I can't play cut shot. All the time i tried and failed. My gentle nudges always end up fielded by the third man (deep), deep cover and fly slip.
6. Dusty pitches behaves most noticeable way. I simply don't get it. Once, batting first here was easy. While chasing, it gave stiff challenge. Run rate drops, deliveries became stocky and slowish. I often struggled with timing. But in another match, batting 2nd was seemingly easy too. Couldn't quite understand the deal here.
