I've just played Australia on test mode with England. Bowled them out for 95, and then for 130 on a dry wicket at the Oval. Ended up recording victory on the morning session of the third day (lost 50 overs to rain), winning by 9 wickets.
Ignore the line and length. The marker when I bowl is grey, though I think that is because it is on test mode.
When bowling, if you bowl up to the power line, the ball will have an extra kick and bounce up higher than usual. In my test match v Aus, I bowled about 40 extras, but it's worth it as the extra zip in the ball usually gets people out, though using the seam on a slower delivery at around 60mph is also effective.
Edit your field, the default one is poor. Against New Zealand with Aus, I was using 5 slips in an umbrella formation, and having Warne spin from leg side to off quite short and fast, the batsman was trying to knock it square, and usually it carried through to about 4th/5th slip.
When I'm fast bowling, I tend to bowl short a lot using the pacey bowlers who can get up to 85mph+. Bowl from around the wicket to the right hander's offside, with the bowling marker about half way. A normal ball at pace, then one that'll go into him using the seam, at pace, and swing it a touch away from him. That has quite a decent success rate with the slips I found.
When a batsman is high on confidence, you'll find it hard getting him out. Don't try and attack the wicket, bowl for the maidens, or try and rough him up. Even if it costs you 12 odd runs, make sure you slam the ball into him, follow it up with a full length slow ball, then either a bouncer or yorker special.
If you want to go over the wicket, go short-mid length, full pace and outswing it a tad.
It all depends on the shot, but using the batsman timing, his confidence, and whether he played the last ball off of the back foot or not, use that to determine your next ball. I usually bowl a couple of duplicate balls, and then either a slower, or opposite swing/seam. The variation works decent.
The first time I played, Hayden hit me for 250 not out, since, I've not allowed him to get over 40. It's all about patience. If you bowl six different balls each over, you're just prolonging the game even further. Resist the temptation to try and rush and go for the stumps directly, and instead try and catch the edge through to the slips or wicketkeeper.
