Short answer is there is no way to specify a count.
1. Choices are you attempt a steal, runner gets the jump or doesn't.
2. You can take a pitch to combat a pitchout. If the count goes 1-0 another pitchout attempt is less likely, but could occur.
3. In any case I don't think "working the count" is of much or probably any value in one pitch.
4. A "forced steal" will result in less success as you are telling the runner to go "no matter what".
5. Some players turn on "pitch by pitch" when they have a base stealer on and want a deeper experience. Then turn it off when not contemplating a steal.
I've played for over 20 years and can't tell you if the pitcher throwing over has any affect other than getting picked off or not. IOW if the P throws over and you get back safely, is there an affect if you try to steal again. Either lessening the chance of getting a jump, or being thrown out. If there is an under the hood rule on this I don't really want to know.
As for me and what I do? I pretty much look at hold/arm and compare to my guys St-aggression and St-ability and take my chances.
I do #2 on occasion.
#3 I don't do.
#4 I do very rarely. Usually out of frustration of my 8/8 guy not getting a jump on a poor pitcher/ catcher combo.
#5 Sounds fun and I think about doing it a lot, but I never actually have.
