;B[df]C[Hi! We're going to look at an actual game. This will help you develop your sense of play in the opening. Compare these variations with your own thoughts. 

The theme of this lesson is "passive opening." This handicap game was played between a 1d and a 7k player.

mark5000: This lesson is for players coming up to the 9 kyu rank.
mark5000: It's text-based. There's no audio or video.

hopser: Hi mark5000, thank you for teaching us. These lessons help alot!
mark5000: You're welcome!
mark5000: We're coming up to the end. Maybe just a handful of possible topics left.
Аlрhа - 1 5 2: Will there be 1k lessons next?
mark5000: Maybe!
mark5000: 1k would be a big jump from 9k. Maybe I'd do 5k or 3k next.
mark5000: All right. Thanks for watching everyone.

mark5000: Q10 helps, yes. But kicking in a nopen position is also ok if you want to secure the corner a little more in exchange for a better position for your opponent on the side.

That doesn't mean that a diamond is worth precisely 30 points. But it's still huge. Before White invaded, all of White's stones were weak. Since White strengthened some stones, the result is unsatisfactory for Black.]

Sir Clacksalot: is this a pro game or whats the subject here?
G-O: lesson to get to 9kyu by Mark
Sir Clacksalot: right
mark5000: This was a game between a 1d and a 7k.
tpnZbonek: no its 1d White vs black kyu player
Sir Clacksalot: thats usually how that goes
mark5000: Anyway, that's all the game I wanted to discuss. Black played passively time after time and is falling behind. At the same time, White is playing actively and making Black answer each move. I hope you remember to play actively even against stronger players!
bencostrell: Thank you!
tpnZbonek: thanks
torusle: thanks, mark.
hopser: Thank you!! :)
skytale11: Thank you!!
jamessch16: Thank you.
mark5000: Of course, White still has a ways to go before the game becomes even. But if Black keeps playing like this, Black will surely lose. And Black did lose.
V.III.: Thank you !
mark5000: Learn from Black's missteps.
mark5000: Any last questions about the game or about active or passive play?

mark5000: Yes. It's still worse than alternatives.

))(;B[qm]C[Alpha - 1 5 2 would attach here. But this is the wrong idea in the opening. A Go proverb says, "Don't attach to a weak stone." This is because attaching to a stone induces it to get stronger. If you're attacking, you don't want your opponent to get stronger, so the attack would fail.
