i just keep clicking the complete/raise button
but seriously... you have to be careful on your completes when the bbs are super high as villain will have little to no fold equity. but with even stacks around say 100/200 i actually try to amp up my aggrsvness because stealing at these limits is VERY helpful. if i get caught, i just ditch it and go back to chipping away at his stack. I dont see any reason to get super nitty though when bets get higher.
For calling i disagree that it should be the same when limits are low.. i tighten up my defending a lot when the bbs are obnoxiously high. having one or two bad defends in a row will destroy your stack when the limits are high.
hope that helps, not really sure if thats what your looking for...
