after a batsman has settled only then try using shift key to hit sixes. In tests it is easy.. u always get boundaries if u try n hit down d ground early on since there is no mid-on. then after few overs try the slog sweep..its damn effective..after d batsman has 70 odd try six hits over mid on and mid wkt.u can always drive even a slightly wide ball thru covers for easy runs..anything else?
