C[Drakonis: aight
ldlework: hi
ldlework: ok so do you know the goal or rules or anything?
ldlework: i can just start from the top
ldlework: since cole is here too
ldlework: in this game black and white take turns placing stones anywhere on the board
ldlework: the goal is to exclusively surround more empty space than your opponent
ldlework: let's just starting throwing out some stones to see what happens
ldlework: you first
ldlework: you're b lack
Drakonis: i'm entirely new
ldlework: yeah this is just experimental
cole_h: Howdy
grahamc: hello!
cole_h: Howdy :)

C[ldlework: OK

(;W[eg]
C[ldlework: if you play at F2
ldlework: then the two stones, thanks to their direct connection, become one stone
cole_h: Laddering already!
cole_h: Oh, nevermind
]
(;B[fh]
C[ldlework: OK see the stone at F3
Drakonis: yes
ldlework: It only touches one empty space
ldlework: stones need to touch at least one empty space to breathe
ldlework: if white moves at F2, the black stone will have no empty spaces it touches
ldlework: that's a capture
ldlework: hit undo
ldlework: one group
ldlework: now that group has 3 empty spots it touches
ldlework: those are called liberties
ldlework: pay attention to them because they are the core of capturing
Drakonis: E2 G2 and F1?
ldlework: yes
]
(;W[gf]
C[ldlework: btw
ldlework: when a stone has 1 liberty left
ldlework: that's called atari
ldlework: it's precapture
ldlework: if you leave an atari
ldlework: on the opponent's turn they can capture, so you must do something
ldlework: similarly
ldlework: when a stone or group has 2 liberties
ldlework: that's a shortage
ldlework: if you leave a shortage, then on the opponent's turn, they can turn it into atari
ldlework: it so happens I have a shortage
ldlework: and it is your turn
ldlework: you can turn it into an atari
Drakonis: H3?
ldlework: which white stone is in a shortage (2 liberties)
Drakonis: hmm, that'd be E3 then
ldlework: yes, what are the liberties?
Drakonis: E2 and D3?
ldlework: yes
ldlework: so if you want to take one of them away
ldlework: creating an atari
ldlework: you play into one of those spots
Drakonis: i'd take E2 then
ldlework: you get to pick the direction you want to drive the stone
ldlework: that will drive my stone left
ldlework: where i have plenty of room to run
ldlework: the alternative is driving my stone towards the wall
Drakonis: hm, good point, D3 it is then
ldlework: where it can't grow as easily
ldlework: /me nods

(;B[dg]
C[Drakonis: it isn't unlike running someone through a maze
]
(;W[ee]
C[ldlework: yeah
ldlework: or like capturing sheep
Drakonis: playing a shepherd
ldlework: yeah
ldlework: or dolphins with fish on the beach
ldlework: ok what just happened?
Drakonis: so, you're doing exactly what i just did
ldlework: yep
ldlework: so now we're both in atari
ldlework: you can either escape
ldlework: or capture
ldlework: i recommend escaping
cole_h: E4 is now in atari
grahamc: partytime
cole_h: Hehe

(;B[df]
C[ldlework: i'll explain why after

(;W[dc]
C[Drakonis: scoring?
ldlework: nah
ldlework: fine guess though
Drakonis: i have the rules open to help out
grahamc: apparently there are only like 5 rules?
cole_h: "Rule #1: Win."

(;W[fd]
C[ldlework: so
ldlework: we're both pretty safe
Drakonis: i can see.
ldlework: none of us have major weanesses
ldlework: weaknesses
ldlework: wo
ldlework: so
ldlework: you want to curl
Drakonis: any move i can play here would put me in a crappy position
ldlework: you're doing okay
Drakonis: if i were to try to block out
ldlework: you want to bend around the frontlines
ldlework: there are two fronts
ldlework: at the top and bottom
Drakonis: and that's what i thought here
ldlework: you want to maximize your own claims
ldlework: nice
ldlework: you're like the Zerg
cole_h: (except ldle still has 1 atari at E3)
grahamc: hehe
grahamc: is drakonis hustling ldlework?
cole_h: Teehee
]
(;B[db]
C[ldlework: that's too timid
Drakonis: would've been more aggressive to do it up top
ldlework: nah
ldlework: even for the bottom
ldlework: you want to move to the right
ldlework: you're just letting white follow you to the wall
ldlework: and i'll git the stuff on the far right bottom
Drakonis: turtling seems like a poor strategy then
ldlework: yeah you want to "flood fill safely"
ldlework: XD
ldlework: so undo
ldlework: that's the wrong direction
ldlework: D8 is the right direction
ldlework: yess
cole_h: G2 -> H3 -> J4?
grahamc: "turtling" jesus he is hustling ldlework
cole_h: LOL
]
(;W[eb]
C[ldlework: ok
Drakonis: for the swarm
ldlework: i put you into a shortage
ldlework: if you don't "fix"
ldlework: i can atari you
Drakonis: D9 it is then?
ldlework: it seems like that would be a good idea
ldlework: but it's death
ldlework: i'll show why after
ldlework: you want to play simple and strong here
ldlework: C8
Drakonis: hmm, interesting
Drakonis: ah i see
Drakonis: there's a gap in the armor
cole_h: E9?
cole_h: Hm
]
(;B[cb]
C[ldlework: with this formation
ldlework: you're just as safe
ldlework: if white tries to bend around
Drakonis: you can still play on the diagonals
ldlework: they'd need two whole moves just to get past your side here
ldlework: D9 C9 you can just close at B9
ldlework: so while they're doing that you can play elsewhere
ldlework: so this shape is good
]
(;W[gh]
C[ldlework: I'm saying
ldlework: Actually I'll explain after
ldlework: you want E9 or G1
cole_h: You basically get 2 free turns elsewhere if white tries to go in at D9
]
(;B[gi]
C[ldlework: no no
Drakonis: i'm not sure if i follow
]
(;W[hi]
C[ldlework: OK I put you into atari
ldlework: so you have to fix
ldlework: see how G1 only has one liberty?
]
(;B[fi]
C[Drakonis: i can see, yes.
Drakonis: escape it is
ldlework: I have a shortage after this too
ldlework: H1 only has two liberties
ldlework: a black cut at H2 would put me into atari
ldlework: so I must fix as well
]
(;W[ih]
C[ldlework: now we're both settled
ldlework: and it's your turn
ldlework: that's called sente
ldlework: you get to do whatever is in your interest, you're not controlled
ldlework: it's an important concept
ldlework: there's only one move left at E9
Drakonis: i see
Drakonis: this is the winning condition then
ldlework: we will see who's side is bigger
Drakonis: if i don't play this move right, i lose
]
(;B[ea]
C[ldlework: well that depends on how close it is
ldlework: remember
ldlework: territory is spaces EXCLUSIVELY surrounded by one color
ldlework: so until we finish this gap
ldlework: all spots on the board could reach both colors
Drakonis: i see.
ldlework: we're sealing off as a matter of end-game ceremony
]
(;W[fa]
C[Drakonis: C5 E2 D9?
ldlework: I put you into atari
ldlework: E9 only has 1 liberty
ldlework: so you must fix
ldlework: then I must fix
ldlework: my F9 is in shortage

(;W[gb]
C[ldlework: now the game is pretty much over
ldlework: your side is secure enough that any invasion will be a failure
ldlework: same for an invasion on my side
ldlework: so we agree there's no more productive moves
ldlework: you pass
ldlework: and I pass
ldlework: and we count the territory on each side
ldlework: (the computer will do this)

(;W[]
C[ldlework: very close!
Drakonis: hmm
ldlework: I only one by half a stone
ldlework: won*
ldlework: basically the computer does a pretty good job at understanding what groups are dead and alive
ldlework: but it allows you to overrule it
ldlework: click the review that will appear
ldlework: [object Object\]
Drakonis: i held an advantage for quite a while
