It's weird, but that happens to me too, DU.
And what's even weirder...When I first got the game, all the batting and bowling tactics I used worked every time, on every level. But lately I am struggling. Not so much with the bat, but with the ball.
I'm currently doing a Long Tour Of England as New Zealand, and in my first 4-day match against Worcestershire, who elected to bat first, they are currently 2/27 off 12 overs. Bond struck with his second ball of the match and Franklin took the other wicket. But since then, no wickets have looked like falling. What I did was:
* For Bond's wicket, I bowled over the wicket to the right-handed batsman just outside off-stump and just short of a good length. Kept peppering that area with varying deliveries and speeds. Eventually, a full length leg-cutter got him to nick it through to McCullum.
* For Franklin's wicket, I went around the wicket to Jacques and bowled a full delivery just before the crease line and the circle was just outside off-stump. my plan was to force him to drive - it worked, and he nicked it through to the slips.
Since then, though, no plans seem to be working.
