;B[hq]C[Hi! This lesson is about opening rules. There are two things you should be aware of in the opening. First, you shouldn't try to play endgame moves in the opening. In a way, that sounds too obvious. But some players try to. Let's look at an example.

This game was played by two 9 kyu players. There were many big points on the board.

mark5000: Hello everyone. This is a text-based lecture about what to do and no to do in the opening.
mark5000: There's no audio or anything, so if you're here, you're good. :)
Shakes Fish At Sky: nice
Cactus Juice: Buyt are we really here?
Xv8: Is Plato still stuck in his cave?
Shakes Fish At Sky: lets not get metaphysical cactus
mark5000: I can fix your Go. I can't fix your existential crisis.
Shakes Fish At Sky: lol
Shakes Fish At Sky: please fix my go
adamomo: lol
Xv8: My Go has yet to work at all, let alone need fixing
spiritstar42: my existential crises needs fixing but if you can't ill settle for my go
Napster: I agree with cacti
Sukkubix: Thank you for the lecture :)

;W[cq]C[White played at 3-3. This was big. There were many bigger points, but that move was fine.]
(;B[cr]C[Black played here next. What do you think of this move? Many players follow their opponents around the board.

-- chat --
akr: too slow
chess_player: Black probably gained 3-4 points here
Executive Calamari: Not gaining enough
chess_player: But he could have made bigger play in the top right
mayomoyo: Top right or extending to bottom right seems bigger
Metropolis: B's group cant' die, and can't kill w, so the 2nd line move isn't threatening anything. 
]
;W[bq]C[It was time for White to play away, but White responded. We see sequences like these from time to time. It isn't good to make endgame plays when you have many other places to play.

Undercover2019: 017

)(;AE[cq]C[Where should the players have played then?

-- chat --
snakesss: Friendly SYNC reminder, if the moves don't make sense with the text, try hitting the sync button.
mark5000: Thanks.
chess_player: If I was white, I would have played P17
chess_player: Or may be 017
mark5000: Good thought
snakesss: black can do that as well
snakesss: perhaps m3 is an option
chess_player: Is m3 a good option?
mark5000: Good, so all of you are as better than 9 kyu players :)

)(;AW[pr]C[First, White needed to slide into the corner.]
;B[qq]
;W[kq]C[Then this extension is very big. 

Rule 1 of the opening is: Don't play endgame moves in the opening. 

-- chat --
p6109: how about c3
mark5000: c3 was the game move and it was actually ok.
p6109: thx
mark5000: around q2 and p17 were bigger.
chess_player: Can you please suggest how much point is playing L3 worth?
chess_player: As in, c3 probably  was worth 8 points? Am I right?
chess_player: Or is this a bad question?
Metropolis: The w group can be badly attacked without l3
snakesss: if black has l3 instead of white on this board, i think white is dead, so l3 is worth the entire bottom
mark5000: I think in the opening it's not a good question for most players to be asking. It's not because this information isn't useful, but if you're a DDK player, painting in broad strokes is more important.
mark5000: If you're liable to follow your opponent around the board and make endgame plays without thinking, it's of no consequence that you can count point values precisely.
mark5000: Yes, that's fine too.
mayomoyo: Can L3 be played before Q2? If black secures the corner, can't white make a base on the other side, with J2, for example?
chess_player: Hmm
Kryswilx: i see this borad bad for white
mark5000: Let's move on.

This position is from a game played between two pros. What's the biggest point now? (The white stones on the right are fine for now.)

-- chat --
snakesss: o9?
mayomoyo: F3?
mayomoyo: F3 is biggest move but not most urgent, I mean
mark5000: Good clarification
ZedSG: I like cactus' variation
mark5000: Cactus Juice, White surely won't play move 2, will she?
ZedSG: I mean, us ddk would
Decros: hello, wat's this?

(;B[fq]C[For Black, this approach is huge.]
)(;AW[hq]C[On the other hand, White would also like to play here.]
)(;B[hc]C[Black, however, ataried here in the actual game. Moves on the right side were also possible, since there's an unresolved, but stable, fight there, too.

snakesss: hi, demo board  text lecture by 5dan
snakesss: about opening
mark5000: Would you all answer this atari?
Cactus Juice: I wouldn't, feels small
snakesss: ^^
Decros: nope
ZedSG: not that small to me, black can follow with k17 or k18
Undercover2019: jump 07
chess_player: Yes
mark5000: Would you allow Black a flower (ponnuki)?
snakesss: i might cuz of k16
]
;W[gd]C[Even though playing in the lower left corner is big, you mustn't allow Black a diamond shape by capturing this stone.

-- chat --
chess_player: I would want to do that because the group in the top right mid is actually very weak
snakesss: cool
]
;B[hd]C[So White connected and Black pushed.]
;W[he]C[White still couldn't play away, so White haned.]
;B[ie]C[Black haned too,]
;W[id]C[And White cut immediately.]
;B[hf]
;W[ge]
;B[ib]C[In response, Black played a tiger's mouth to defend the two stones. Here's a question: Can White play away now? The fight was still underway up here, so a playing away wasn't a good idea.

-- chat --
chess_player: No
p6109: no
Soineanta: I don't think so.
chess_player: It would still leave the white group in the  mid center in danger
ZedSG: no, that top group looks like it needs some help
mark5000: You all are too good.

Shakes Fish At Sky: i am not keeping quiet
]
;W[if]C[After these exchanges, White cut here and began fighting. What do you think of this sequence? Had White played away, Black would have attacked White's group at the top, taking control of the game. Previously, we talked about how a battle can sometimes begin in the opening. When that happens, don't rush to play away!

-- chat --
Shakes Fish At Sky: its just I am having dinner
chess_player: Still in the fight, so black should respond
Cactus Juice: mark, why did white attach q17 instead of slide?
Shakes Fish At Sky: Q18
p6109: I would have finished L18
snakesss: white had one weak group that needed help
mark5000: White attached at q17 instead of sliding to keep sente.
Shakes Fish At Sky: or C3
mayomoyo: I was also thinking L18
Cactus Juice: l18*
snakesss: so, white has to cut? so black cant fix?
Cactus Juice: snakesss: yeah, fixing there is huge for black, works well with botom and right :/
mark5000: Correct.
mark5000: This is secondary to my lesson though.
mark5000: This part of the lesson is that White should not tenuki the first move.
Shakes Fish At Sky: I would have made that mistake I think 
Shakes Fish At Sky: cause i am bad
mark5000: It's suspiciously easy to fall into this trap.
snakesss: which mistake? i would have done most of these mistakes in the 2nd rule part
mark5000: When it's highlighted as a Go problem, like here, it's easy for everyone to see it.
mark5000: But when you put it in your own games, suddenly you lose all good sense and start making these mistakes you know you shouldn't make.
mark5000: That's why it's important to talk about it so much that it becomes second nature.
chess_player: So, how long do we keep this fight so that it doesn't contradict the first rule?
mark5000: If it's second nature, you'll do it in your games by instinct, and you improve your Go skill.
mark5000: Good question.
mark5000: If a battle for the health and security of groups is underway, don't tenuki, per rule 2.
mark5000: If the battle is no longer underway, or if the battle no longer concerns the health and security of groups, but only points, then rule 1 applies.
snakesss: but first ponnuki was just one stone and good shape - no security of groups endangered
mark5000: It did endanger the upper right white stones, if you recall.
snakesss: ok
chess_player: Which three black stones?
