OK, inebriated or not, that's very helpful. Thanks ! Unfortunately I'm not right now.
Though I was thinking I could recognize the difference in context and understand 知っているas in the state of having found out or or having become acquainted with some objective 'standards' for what it means to be a strong person. Applying those to oneself as a mental process rather as opposed to an innate, intuitive understanding. It just didn't work in the negative: Jibun ga tsuyoi ka dou ka shiranai ??? makes me nervous.
But that is my thinking. So please enjoy your mystery from now
on, too!

Hmmm, grrrr,
A word of warning : people who have plenty of things to learn yet maybe better avoid reading below because I am writing something about very intricate and maybe useless thing with only my intuition as basis.
Well this time I should start with the conclusion because I did not do a good job last time.
俺は自分が強いと知っている。
There is nothing wrong with this statement. In fact many native speakers won't even care or notice the difference between 解っている and 知っている in this context. Also there is a expression like 敵を知り己を知らば百戦危うからず
But in practice, 俺は自分が強いと解っている is used far more often than 知っている, because people feel it more natural without knowing the reason and maybe there is not a reason as a matter of fact.
To think of the explanation for the more frequent use of 俺は自分が強いと解っている、over 知っている、I feel it is because coming to understand or know that oneself to be strong is always tied with some sort of experience rather than from someone telling it to us or from reading books.
And because the knowledge of oneself being strong is always derived from personal experience, thus it is solved or understood by oneself, we tend to use 解っている over 知っている in this particular given context.
Another reason I can think of is because in the context where such statement as 俺は自分が強いと解っている is made, speaker may would like to emphasise the fact that one knows it for certain often:sometimes people say 知っているだけでは十分ない to say knowledge is inferior to experience or practice, so 解るsomewhat sounds stronger than 知っている。
( I think this is a fallacy because experiencing something often only shows one aspect of things.)
As to what you have wrote:
as in the state of having found out or or having become acquainted with some objective 'standards' for what it means to be a strong person.
I agree and your understanding is very good. In certain context 知っているis far more suitable than 解っている。
let us see examples because it is highly dependent on context and what is meant.
己を知る（理解する）事は大切ですよ。＝＝＝＞For there is this expression 敵を知り己を知らば百戦危うからず we can use 知る。but not much difference between the twol.
自分の強みも弱みもよく知って(理解して・解って)いる。負けようがない。==>This is as a result of studying oneself, 知っているmaybe better but like above not much difference
自分を知る（ 理解する）ために修行をしているのです。＝＝＝＝＞from 全知全能,
知る seems to hint something deeper than 理解 too. Probably this is what you mentioned.
To reach understanding of inner, innate and principal of oneself or to gain insight into true-self that simple experiencing or experimenting never allow oneself to reach. This 知るprobably was like a jargon to start with but now part of Japanese.
強さとは何かを知らず(理解せず)して、どうやって強くなるおつもりで？
じゃあ誰が強さって奴を一遍の疑いの余地もなく知っているって言えるんだ？
Same as above I guess.
お前自分が他の奴より強いって解って(知って)るのか？
解ってるさ。＝＝＞I think 解ってるhas stronger emphasis than 知っている。here because we can say 知ってるだけじゃ十分じゃない、解らなくちゃ。
What really troubling is that someone could say something like 解っててもだめです、知らなくては。in the same sense as 自分を知る. This comes down to subject specific definitions of a word or jargon or method of attracting people's attention: In English, means is a way of doing something but also is an average and nonsensical sentence mayamuse people .
自社の強みを理解する事はとても重要です。==>理解is refereed word because it sounds big , thorough and convincing.
俺は自分が強いってちゃんと解ってるんだよ。===>Encouraging one self because he/she doubts in oneself. 解っているsounds slightly stronger than 知っている。to me.
In conclusion it comes back to the start, it is very subtle and even the intention of writer and understanding of readers might be different sometimes.This is all because any language is in continuous drift and meanings of words always changing in slight degree. We have to provide a definition of a word in context when we are writing and we have to find one when we are reading or guess it from the common usage pattern.
The reasons I have wrote this sickeningly unreadable note is because:
1)academic people would not like to touch this(because too subtle and time consuming)
2)teachers often consider talking about things like this a wast of time, so learners who reached to certain degree of proficiency might not even have the chance to think about this while these things are pretty important to gain a mastery over any language.
3)And lastly I have not written in English for so long now...
Anyway, Thank you so much Elizabeth, for answering my question in Learing English section
p.s
It just didn't work in the negative: Jibun ga tsuyoi ka dou ka shiranai ???
It is fine,
君自分がお酒に強いって知ってる？
自分がお酒に強いかどうか？知らない。＝＝＞not interested or something like that. Without ? the sentence sounds so verbose..
p.p.s
But that is my thinking. So please enjoy your mystery from now
What do you mean by the mystery?
p.p.p.s
If you can give me some tips for improving my writing from reading the above that would be swell: I would not be able to fix all of them up at once so one or two is enough.
