Review by: ...

Hi! Let's explore some 5-4 josekis. There are many reasons to know 5-4 josekis. First, you might want to play a side-focused game and take outward influence. Second, your opponent might play 5-4, and you should know how to answer. Third, your opponent might ignore a high approach to a 3-4 or 3-3 point, and that situation would resemble a 5-4 pattern. Because of this, 5-4 josekis are worth remembering!

The main purpose of a 5-4 play is to make influence toward one side. Here, this 5-4 point makes influence facing the right side of the board. Because of the properties of the 5-4 point, the right side area will likely become Black's area of influence, and later on be useful for attacking. It may also become territory at the end of the game. In exchange for this influence, you should know that the 5-4 point also invites your opponent to occupy the corner.influence facing the right side of the board.

Move 0 + 1

[21:28] mark5000[6d]: Thanks!

[21:28] ArmenTsirunyan[17k]: Does it make any sense for me to watch this lesson if I don't know what exactly a joseki is :D

[21:28] mark5000[6d]: Yes, definitely

[21:28] taatelikakku[1d]: so far I have ignored 5-4 opening like it didn't exist. probably good time to have a look

[21:29] mark5000[6d]: This series is for players coming up to 9 kyu. But it covers basics, and I explain things along the way.

[21:29] mark5000[6d]: Joseki means fair corner sequence.

[21:29] jillgoodgal[6k]: joseki just means a known sequence which is considered a reasonable outcome for both sides

[21:29] jillgoodgal[6k]: or that

[21:30] mark5000[6d]: Yours is more descriptive :))

[21:30] Xaloc[6d]: I must admit that I avoided to play this opening!

[21:30] ArmenTsirunyan[17k]: thank you!

[21:31] 非凡围棋[7d]: a international lesson :)

[21:32] Holonium[9k]: I am facing a 5-4 opening in a corr game atm. So good timing to see this lesson ^^

Move 0 + 3

[21:34] seedrick[?]: but sensei, my 35 kyu brain is telling me "3-3 invasion"

[21:34] seedrick[?]: ...never mind, i see you addressed it

[21:34] seedrick[?]: carry on

[21:34] mark5000[6d]: Oh, we will!

Move 0 + 10

[21:37] seedrick[?]: sensei, is attaching here bad?

[21:37] seedrick[?]: R15 instead of S15

Move 0 + 12

[21:40] Avatar33[10k]: White is likely to get sealed into the corner in this case?

[21:40] seedrick[?]: yup

[21:40] mark5000[6d]: Yes.

[21:40] seedrick[?]: thanks sensei!

[21:40] mark5000[6d]: That's the nature of the 3-3 point invasion.

Move 0 + 11

[21:42] 非凡围棋[7d]: thanks

[21:43] mark5000[6d]: One moment.

[21:43] mark5000[6d]: Baby emergency :)

[21:44] mark5000[6d]: Back now

Move 0 + 16

[21:51] Avatar33[10k]: If there is time, could you show us why the cuts don't work well.

Move 0 + 17

[21:55] Avatar33[10k]: Yeah, this variation whas the one I was scared of

[21:55] Avatar33[10k]: Interesting, thanks

Move 0 + 14

[21:58] mark5000[6d]: So remember to bend under here!

[21:58] mark5000[6d]: This move helps separate novice players from the higher ranks.

Move 0 + 11

[22:05] jillgoodgal[6k]: what about Q13 for black there instead?

[22:07] mark5000[6d]: Also possible

Move 0 + 12

[22:08] jillgoodgal[6k]: seems to cover the white push under at S14 better

[22:08] mark5000[6d]: Yes

Move 0 + 14

[22:14] Avatar33[10k]: That sacrifice proverb will come in handy.

[22:15] mark5000[6d]: :)

[22:15] mark5000[6d]: Adding one stone to the sacrifice sometimes opens new possibilities even if they are both captured!

Move 0 + 7

[22:15] jillgoodgal[6k]: almost always should play down from third to second line in that case, I think

Move 0 + 31

[22:16] 非凡围棋[7d]: Variation: 1

Move 0 + 8

[22:18] jillgoodgal[6k]: cut!

Move 0 + 19

[22:20] 非凡围棋[7d]: Variation: 2

Move 0 + 17

[22:23] mark5000[6d]: That bring me to the end of the lesson.

[22:23] mark5000[6d]: Any last questions about the 5-4 point?

[22:23] Benzi[4k]: Thank you that was excellent

[22:24] jillgoodgal[6k]: it often occurs in reverse

[22:24] Avatar33[10k]: Thanks Mark

Move 0 + 8

[22:24] jillgoodgal[6k]: attacker plays 5-4 against a 3-4 opening

Move 0 + 2

[22:24] mark5000[6d]: Oh yes. I mentioned it briefly at the start

[22:24] mark5000[6d]: If you leave this alone, it's a 5-4 pattern.

Move 0 + 2

[22:24] mark5000[6d]: Same with this

[22:25] mark5000[6d]: Playing elsewhere leaves a 5-4 pattern. So even if YOU don't play 5-4, you may walk into one of these patterns anyway.

[22:25] 非凡围棋[7d]: 3-3 point have this variation？

[22:26] mark5000[6d]: Sure. It's uncommon, but this approach isn't unheard of. Actually, I covered it in an earlier lesson.

[22:26] jillgoodgal[6k]: yes I remember, it can be better than 4-4 when you have stones behind on that side

[22:26] mark5000[6d]: A is the most common, followed by some approach at B-E.

Move 0 + 1

[22:27] mark5000[6d]: All right. Thanks for watching, everyone!

[22:27] jillgoodgal[6k]: thanks for all these lessons!

[22:27] mark5000[6d]: This is my last lesson in this series. I've done 54 of these!

[22:27] mark5000[6d]: Find them all at becoming 9-kyu-a-series-for-beginners

[22:27] Avatar33[10k]: Awesome series

[22:27] Tehben[14k]: thanks a lot

[22:27] jillgoodgal[6k]: when do the becoming 5kyu ones start?

[22:28] mark5000[6d]: I hope they help you break through the beginner ranks :D

[22:28] mark5000[6d]: I haven't decided. The newborn life may mean several months before I return to it.

[22:28] Avatar33[10k]: How much does theory matter vs practice?

[22:29] jillgoodgal[6k]: huge!

[22:29] Avatar33[10k]: Should you spend 50/50 time on both?

[22:29] Avatar33[10k]: Or should a beginner focus more on just playing

[22:29] mark5000[6d]: Practice is more important. But you have to be intentional with your practice. Practice with purpose! Purpose to play a little better than the last time, using knowledge you've built on.

[22:30] jillgoodgal[6k]: the theory to me really helps you figure out the mistakes you are making

[22:30] mark5000[6d]: If you don't know what to do better, then you need a source of new ideas (theory).

[22:30] 非凡围棋[7d]: really a good lesson i always play a single beginning

[22:30] Avatar33[10k]: Thanks all.

[22:31] mark5000[6d]: I always recommend playing simply to beginning and novice players. But don't be afraid of fighting if that's the best path forward!

[22:31] mark5000[6d]: If you dodge all fights, your opponent can bully you without bad consequences.

[22:31] mark5000[6d]: Happy Go playing!

[22:33] JohnCollins[6k]: are there any problems to help learn general fights as opposed to L&D and such?

[22:33] JohnCollins[6k]: Just "come off better in this position" rather than a bit kill?

[22:34] mark5000[6d]: Learn what good enough looks like

[22:35] mark5000[6d]: Killing is rare. Instead of killing, try punishing mistakes by developing more efficiently than they can afterward.

[22:35] mark5000[6d]: Poke weaknesses they leave behind. Make them answer your moves with moves that don't help them, while your moves help you make profit.

[22:36] mark5000[6d]: With that, I'm off. Thanks for watching! Keep sharing this series with new players you meet, if it helped you!

[22:37] JohnCollins[6k]: thank you
