This is a tough learning position for me. I don't see White's weakness, but the move I settle on is a blunder and the computer reveals it by honing in on the weakness I missed.

Look for yourself before reading comments. White to move.

I noticed white's strengths. Extra passed pawn, great dark square pawn chain, excellently positioned Knights and Rook on the 7th rank.

Weaknesses I saw for white was the knight on c5 was under threat. That's it.
I missed...Ph2 as a big weakness! Petrosian played Qg1 to defend it. I didn't even think White had anything needing real defending.

I liked Nb6, pushing back the Rook and preparing to push the passed pawn. The computer replies ...Bd6, targeting Ph2. White's advantage is gone.
I'm still working through this book on defending, because it's obvious there are defensive things I am completely blind to. It's not a big deal against players below 2000, but stronger players will destroy me there. "New Art of Defence in chess" by Andrew Soltis
For those wanting to understand why Ph2 is a weakness, it's because of how quickly black can generate an attack against it and the white King.

Via Bg4, Rh5 and Bd6. Suddenly there could be 4 black pieces near the white King. 4rbk1/R4p1p/2p3pq/2Nr1b2/2NPp3/4P3/P4PPP/2R1Q2K w - - 1 29

If I react negatively to another's speech I'm creating a "censorious environment" that causes them to self-censor.

But my withholding my reaction isn't self-censorship? 🤔
I think the entire "censorship" discussion among the public to be silly.

First, speech cannot silence or censor speech. Setting aside the hyperbole, telling me to restrain my speech is the same as claiming my speech restrains that of another.
Each individual gets to determine their own reaction to speech. Where they draw the line is up to them. Everyone has thresholds at which they will react negatively.

Debating each other's line is reasonable, the "censorship" stuff though, isn't.

I don't think it makes sense to navigate social issues without bias. If I'm looking to solve for any social issue, I'm certainly going to be biased towards results that help towards my objective.
We can't for example say we want more women in Tech and think we can do so without displaying bias. Even going against the status quo is a demonstration of bias.

Our time and energy isn't infinite. Our choices reflect our priorities, our biases.
The definition of bias generally implies unfairness, but here's the thing, a lot of people love the status quo and think attempts to change it are unfair.

Ultimately what we must do is stick to and defend our principles and goals.

Kenny going back in time to retrieve an old BS argument blaming African-Americans for the 2007 financial crisis.
Notice how Kenny took the time to specifically highlight African-Americans in his tweet.

He's really got to work on his whistling game. It's too obvious.
I remember when a well-known white nationalist college professor said America would be better off with fewer Asians.

Kenny, an advisor for an organization "against racism", could only muster saying she was wrong.

That's the strongest condemnation dontchaknow. "Some progressives have tweeted at me for not denouncin

There are zero actions necessitated by a child adopting a gender or a sexuality.

A parent can accept a child's decision/announcement and still be a parent with full rights
When it comes to trans kids (that's what this really is about), a shell game is at play.

- It's about parent rights when the parents *are not* trans affirming

- It's about child health and psychology when the parents *are* trans affirming.
I think it's all really complicated for trans kids and their parents already. We are mostly just adding political fuel to the fire.

At the end of the day I support trans kids and want them to be as fulfilled and happy as possible, even if I can't tell them the best way.

This was a fun one, and the comments were really good too. So let's do a thread on the position and positional #chess in general.
High level guide to assessing a chess position.

- Material
- King safety
- Piece Activity
- Pawn structure

Stronger players have much deeper understandings of these concepts and sub-factors within, but we all can use these at our own levels.
So in this position:

- White is down in material (1 less pawn).
- Black's king is safer (less access points to it)
- White has a better pawn structure (that pawn on d6 can't be defended by pawns)
- Black has more active and scary pieces (Queen and Bishop near white king) r2r2k1/pp3pbp/3p1np1/1N2p3/...

Police are too quick to break up and use violence against protests about police brutality, racism and Indigenous rights.

Police are too slow to break up protests about Covid mandates.

It's hard not to see the role demographics plays there.
I believe in the right to protest, even if it inconveniences. I also believe that the state has a responsibility to act when it exceeds reasonable limits. Like most cases of civil disobedience, arrests are an expected cost to pay. If no cost, no deterrence.
Individuals who disperse when asked to shouldn't face consequences. Authorities shouldn't escalate with violence (e.g beatings). There's a balance, and the refusal to make it clear that the balance isn't driven by demographics and politics, speaks volumes.
