The best way to force errors is to use deep slices. They can really throw your timing off and at times even when you get a perfect timing off a deep slice the ball can still go out. Once your stamina gets low deep slices can be very lethal. At this point floaters and errors(forced/unforced) will be more common off slices. You can use other shots as well, but sliceing, especially deep slices, seem to force errors the most.
About balls going out, it depends on the playstyles. Serena can force errors just off the sheer power and precision of her shots. So if an offensive baseliner is involved, then yes you'll see errors. Fed can force them too, but not like serena. Rafa/ivanovic not so much.
