On Jun 9, I copied this problem from Facebook and posted in WeChat group, with the following original hint:

Berger, 1888 white to move and win. (#16)

Somebody suggested Qb8, only one move. There was no followup to this move. I suggested to use the two weaknesses, g2 and h2 squares. My conclusion was to reach g3. I claimed I knew, but found a hole in my approach right away: I will be checked.

Jun 13, I re-posted the problem. I suggested another approach and drew an illustration diagram, but it ended up with question what can we do after Qf4 Ba6?

Jun 21, I asked again. No response.

July 4, I exclaimed that the problem is so hard. After 15 minutes, I claimed I had another solution, but again I found some small holes. The problem is put on backburner again.

July 26, I asked again. Another expert made another suggestion, with no confirmation from anyone.

Nov 22, 4 months later. I re-posted the problem. The same expert made couple suggestions, and some seemed to be positive progress.

Last night, Nov 25, when I woke up in the mid-night. The problem suddenly comes into my mind, and I knew I could solve it. I spent about half hour to solve it completely in my mind. Then fell into sleep again.

Finally, after**5 months 16 days**, we have the solution!!!

I will explain the solution in my YouTube channel.

Soon after I started to advertise, Jairo found me because he needed someone to teach after school. He gave me a hint to check out Steps. I immediately went to the USCF Shop to search and found a set of workbooks and manuals. When I received the books, I really felt good, and I made my decision right away. THIS IS IT!

First impression:

1. Rich in content, clear knowledge points, and step by step

2. A lot of practice, save the trouble of finding exercises for students

3. Not in a hurry

I used some Step 1 content in the after-school class, taught a Step 2 class, and prepared the initial teaching material for my daughter's All-girls Camp in November.

The first is the length of class time. The online class is 75 minutes, and the in-person class is one hour. The online class is basically a half-hour homework discussion, a 15-minute new lesson, and a half-hour commentary on students' games. Online class students do not play games in class. Parents make an appointment after chess class, according to the pairing I give for the week. The in-person class is 20 minutes of homework discussion, 10 minutes of new lesson, and half an hour of game playing. Playing chess is a feature of the in-person class. Parents who are willing to sign up in-person class are also interested in this opportunity to play against their classmates. But the disadvantage is that the chess games in in-person class cannot be commented, because almost no one records it (clearly and correctly), and even if it is recorded (my advanced class is required to write notation, for preparing for tournaments), there is no guarantee that I will be able to play the game out again with the score sheets.

From this point of view, the teaching time of online courses is obviously more than that of in-person courses.

In terms of curriculum design, online classes are about one academic year, with thirty-four lessons, one step in a year. The in-person classes are a quarter and a section, 10-12 lessons, and there are about 30 lessons in a year. However, many students only sign up for one or two quarters, so it is difficult to ensure the continuity and the final teaching quality. It is difficult to guarantee. There are new students every quarter, so taking care of them is another task. Teaching content will be discounted.

Online classes are video recordings of the entire course, while in-person classes are only videotaped for computer teaching part.

Whether it is online or in-person, my teaching is always of a question-and-answer mode. The teacher is responsible for asking questions and the students are responsible for answering. All are fast-paced. In online classes, we cover at least 36 homework questions and about 10 positions for new lessons. We can only do our best in in-person classes, and the goal is the more the better. Thirty questions should be fine. Therefore, we will see almost 1,500 positions a year in online courses, 350 positions in in-person courses a quarter and about 1,000 positions a year. Therefore, we will solve many more problems in a year than many other classes.]]>

Carissa's dad gave us an answer two days ago: "I just want my kid to reach his full potential."

Ye Shuai's "developing one's potential" hits the spot. Everyone has the limit of everyone's ability, including potential. If you can explore it as much as possible, then this chess is worth playing. A lot of kids just waste their innate abilities and years, including two of my own. As a parent, it is worth thinking about how to guide children to develop their abilities, what conditions to provide, what kind of environment to create, and what opportunities to seize.]]>
