Chien (fhunfi) is really great value, passionate about chess, kind, and generous with time.
Even if you don't become student, he would be happy to be your friend for chess learning journey. Also, Chien always replies to my chess emails promptly, so it feels like having a chess buddy accompanying on this chess journey.
For recent past few months, I develop Daily Course by email.
mainly for those who can't afford to pay weekly regular lesson (USD 15/hour) via live session (skype/ chess com classroom feature).
It run successfully and they find it very helpful.
How it works?
It is an email-based course, on daily base, where typically I will give you a position (or discussing a whole game move by move / scene by scene) and asks you to think about the plans and the best moves. When you can't see the correct answers, I will email you back with a hint, or if I find the correct answer then I will proceed to the next question on the position.
From the daily course you will be learning a mix of middlegame strategy and positional understanding. In some case this will also relate to Endgame and specific openings but usually it is applicable to a wide variety of different openings. This is not the usual Tactic/ Puzzle test that you can find & practice easily from many sources by your own.
To finish discussing 1 Test, often it will take 4 - 5 email reply back and forth / question & answers from 1 scene to next. as we are discussing your answer.
And instead of giving all solution at once, I will always give small hint each time if needed ... with purpose that you will find answer finally by yourself aka using Socrates method - I will stimulate your thought process so that you will find the answer yourself with my minimum hint.
After Test-1 finished, then I will send you next test, and so on.
You will just need 5 - 10 min / max 15 minutes daily for thinking of solution.
and you don't even need to do it / reply the test every day if you are busy on any particular day- the speed it at your control - as soon as you replied the test, then I will promptly respond back & so on.
The motto is: Every day is small steps of improving.
With very affordable (USD 25 monthly) for this Daily-Course-by email program, you can give it try for a month, and only if like it & find it useful, then you can think to pay for the service at the end of the month. You have nothing to lose as there is no obligation to pay the service at first month if you don't find it helpful. I will even not mind if you can only afford less than normal fee, as long as you show some passion & diligence.
Please DM me for more detail.
