coaching

Blind leading the blind. Somebody analyze this game:

"Alright so in this opening you can play Qh5 after white played Nf6 to develop"
I’m sure the OP had done preparation and meant to play b6, g6 and e5 to reply against the most common opening e4. To be fair, he isn’t here to defend himself.
It would also make sense if you at least fianchetto one bishop.
Even then, why would you advocate the Owen Defense instead of simply replying with e5 for the 300 level?

I do think some kind of certificate of competency should be demonstrated before teaching. show me your level of abilty
Players should always scrutinize the information they read or are given, but it’s not the source that needs such scrutinizing it’s the actual information. Chess is a game of truth, it’s factual, whether it comes from a GM, IM, random internet guy rated 500, Carlsen, or an engine, the Lucena endgame is the Lucena endgame, it doesn’t matter who’s teaching it as an example.
Additionally, a lot of people who teach don’t have teaching credentials, there’s a difference between someone skilled in the game and someone skilled in teaching the game. I’ve interacted with multiple titled players over the years who are definitely skilled at the game, but can’t teach well at all and untitled players who can teach quite well and have many students. Judge the teaching, not the teacher. Have any of you taken a lesson or seen the OP teach?

I appreciate the thoughtful response.
Would you take karate lessons from a white belt?
That wouldn’t get you very far on the streets.
Do you see what the OP is playing? Replies to e4 with b6, 2. X, g6 3. X, e5. No fianchetto bishop. Proceeds to drop a queen in the opening.
Is that what you teach 300 players?

I agree with you with the first part, the elo doesn't qualify your coaching skills, like for example I consider IM Andras Toth the best chess coach you can possibily hire, and trust me if i had the budget, I would choose him over Magnus Carlsen or any other super GM... so you're correct on that part. That being said, you also have to keep in mind that the job of a coach is to share with you the correct mindset, ideas and plans to make you effectively a better player, and realistically speaking, a 600 rated players has nothing to share: like literally the only difference between a 600 and a 300 is that the 600 blunders less, that's it. Imo he can play games with a 300 and maybe help him that way, but we shouldn't talking about coaching... coaching is something else..
Over all as a community we should encourage each other to grow, learn, and progress, not put others down for offering to share knowledge. Consumers should always do their due consideration of the product/service being offered but let’s not blindly criticize it on the basis he is a lower rated player. Teaching can be a great motivator to master the material they are teaching as well, which helps both parties too.
A quick example, years ago I had a friend and for awhile we’d each pick something to learn and then teach each other the information. There’s a benefit and motivation driven to learning material effectively to teach it, being accountable for this process, and that likewise shouldn’t be discouraged either in my opinion.
To my knowledge nobody here has approached the OP concerning what he teaches or how, or taken any lessons from him. So why knock him over it? Seems unproductive and honestly rude to me, doing so on assumptions and not with actual facts.
It’s be another thing to say, this guy is charging $20/hr and teaches wrong things, be warned. But to present, this does not seem the case. I’m not sure he’s even charging for his service. So why not encourage learning and growing? At least be silent on the matter unless you have facts concerning this coach to warn others, yes?

If the OP would have said " i want to help 300s by playing with them and teaching them the lucena position" ( random example), I guarantee you nobody would have said anything... but as i said, coaching is not "helping", it's something else... and it doesn't matter how hard you're trying to convince me, a 600 is not able to coach anyone effectively, sorry.

First of all, is not my interest to put anyone down, in fact i didn't say anything mean to the OP and i just participated at the end of the discussion because i just wanted to puntualize a thing or two, since i think what i'm saying is objectively correct. I'm more than happy to help people out and see them succeed in life ( not just in chess), so stop this drama with me..
Second of all english is my 4th language, so maybe i'm missing something, but i'm quite sure that coaching in chess is usually intended as mentoring, not just helping someone.. and a 600 rated player can teach some concepts that he knows, but if he says " Coaching players rated 300", he just sounds ridicolous... Btw I don't want to prolong this discussion any longer because i think we are basically saying the same things over and over, and it's quite usuless. I know you're gonna respond and i more or less already know what you're gonna say, but please stop accusing people of putting others down when they're just being objective and nobody said anything mean... Cheers my friend.
