IT IS BETTER TO CASTLE AWAY FROM

Often, it is better to castle in the open positions, even if it costs some material.

In the rapid game played on CHESSCom, my opponent was too late to castle.

Below is the analysis of the game

I SHALL STOP SOLVING CHESSCOM PUZZLES

OK. I have received a puzzle rating above 3400. One day, it was 3448. 

I shall stop solving CHESSCom puzzles from now on.

The reason is the poor quality of the puzzles with higher ratings. The rating points and the target times are also not well-tuned.

Yesterday, I got Kubbel's endgame study as a "tactics puzzle" to solve with the target time of 30 seconds.

Today, I got several messy positions as "tactics puzzles".

The last "puzzle" was not convincing at all. It looked somewhat like an attack with several options to continue that attack at several points.

It is evident that no human being has ever checked these positions and their solutions; there is too much trust in computer algorithms.

The themes of the puzzles are too often highly misleading, too.

By the way, other chess platforms have similar features.

I am sharing here the CHESSCom puzzle (#59358) that I failed to solve. Its pass rate is below 20%.

The puzzle itself is excellent.

However, I am dissatisfied with the so-called "target time," which is below 1 minute in the present case.

If you are not well-trained in the queens' endgames and/or not acquainted with the rare theme included in that puzzle, then hardly you can solve that puzzle in 10 minutes.

Please note that I keep in mind that you have to see the solution from beginning to end before moving any pieces! You do not "solve" the puzzle; if you are making naturally looking moves, the computer replies, and you arrive at the crucial position to start calculating the difficult move.

Thus, it is not a tactics puzzle at all. Rather, it is an endgame etude, problem.

The other obstacle is that the CHESSCom puzzles, even those with a high rating, are usually standard. 

Nevertheless, solving any such puzzle gives only 5 points, independent of its difficulty. 

I have obtained a rating above 3400 in puzzles on CHESSCom. Unfortunately, I do not believe I could progress further because, at that high level, the puzzles are less tested due to the fewer solvers. There are already too many invalid puzzles like that one, which demands that you be a Carlsen and solve in a few minutes what others are solving in one hour.
