How to Beat KataGo at 4 stones - Another example where W starts out with San San

 


This example is similar to a previous one in that KataGo starts out by invading the Lower Left (LL) corner, but a different approach is used by B, where moves 2 and 4 are played and then 6, rather than 6 immediately.


Here KataGo has invaded in the UL adn LR corners, and played 31.

The strategy B is implementing involves 4 items:

1. Kill 2 of W's corners.

2. Make a territory somewhere else besides the 2 killed corners.

3. Don't allow W a huge territory.

4. Keep the B groups safe.

The most challenging item is the second one, as KataGo is very good at sniffing out prospective territories and limiting them, especially if there is a weak group to attack, or some problem with the shape. Before 31 was played, there were potential areas to develop in the upper side, right side, and bottom side, although with 13 sticking out, the top side doesn't look very promising.  Once 31 is played, the bottom side looks to be most promising, especially after played 47 (in the next diagram).


Once 52 is played, assuming W can kill the two diagonal corners, B will have a significant amount of territory, which will be difficult for W to match.  B will be trying to kill the two corners, keep the bottom territory intact, and keep the groups safe.  W developing a huge territory does not appear to be an issue.



98 was a very nice move to play, as it simultaneously reinforced the group in the UR, and the territory on the bottom.  B has succeeded in killing the two diagonal corners, building an additional territory, and keeping the groups safe.


These are the remaining moves, at which point KataGo resigned, with B ahead by an estimated 41 points.

Versailles Unveiled: The Power Dynamics of Louis XVI's Salons

Image
  It was the best of times, it was the worst of times. In the heart of Paris, during the best and worst of times, sat Louis XVI, ensconced in the grandeur of Versailles. The salons of the era, with their opulent design and luxurious materials, reflected an age of excesses. Yet, these spaces were more than mere aesthetic marvels; they were potent symbols of the nobility's power. As revolution's whispers grew louder and social disparity starker, these salons served as bastions of the old order, standing in stark contrast to the tumult outside. They were not just about style; they were a response, a bold declaration to a world on the brink of transformation. Amid societal upheaval, within these gilded walls, the monarchy's grandeur endeavored to assert its relevance.

The Secret of Happiness

 This post will discuss the secret of happiness, the subject of many books, and studies, but actually very simple, which is to be grateful, appreciative, and thankful. I understand there has been a fair amount of research into this, but I'm not looked into this, but learned this through my study of narcissism. Narcissism (I'm referring to especially in the context of narcissistic personality disorder) is characterized by a number of things, including excessively seeking attention, excessive dreaming of something better (a better job, a better mate, etc.), perceiving oneself as special and that only other special people perceive this, feelings of grandiosity, an exaggerated sense of entitlement, manipulating others, a lack of compassion for others, arrogance, and excessive jealousy.  I was interested in which of these symptoms is the horse, and which the care, and discovered that the horse is the exaggerated sense of entitlement, whereas "arrogance" is essentially a sy...
