Psychology (including confidence) is an important part of any competitive activity, especially chess, where nearly the whole competition is in the minds of the opponents. Preparation and practice help improve confidence, as well as get ready for the situation one is studying.
Recently my child played in a tournament and performed poorly. This is after several tournaments in which success was had. In one lost game in particular, the opposing player played a very unusual - and generally considered inferior - opening. However, my kid had never played against such an opening, was confused by it, and played poorly. While I don't by any means want to teach poor principles, in order to help prepare for future games in which an opponent pulls out a strange opening, I seek to find such openings for me to play at home, when we are relaxed, and when a "teaching moment" might occur.
Alas I will be the first to admit that I am not a very strong or knowledgeable chess player. Thus I asked the question (For training purposes) Are there any openings with rook pawns that are more effective than others (and if so, what are they)?. It has gotten several answers, and a couple of them have been helpful. However some of the answers don't address what I am asking. Instead, they just state that I should teach good principles in spite of the fact I already said I want to do this in the original post. I have made comments trying to elicit more helpful suggestions; unfortunately, these seem to lead to testy exchanges instead of improved answers.
I just added to the post in an attempt to better explain myself.
So, am I clear enough here? Is the reason I'm not getting helpful responses just due to a lack of openings that fit my question and yet some people think they should answer anyway (and yet not with something like "Sorry, there aren't any.")? Or do I need to improve the question somehow?
