ldlework: OK we should play in the corners
ldlework: fine
ldlework: but where?
ldlework: imagine they each just bought a new house
ldlework: they come home for the first time, brew some coffee
ldlework: then step out into their back porch at the same exact time
ldlework: just to see the other across the yard in the other house
ldlework: they realize they're gonna have to share the same yardage with each other
ldlework: fuck that they think
ldlework: they run to their garage
ldlework: and start grabbing plywood and nails and such
ldlework: they frantically run around driving posts into the ground
ldlework: "My yard!"
ldlework: *slam*
ldlework: "No, MY yard!"

ldlework: Well blocking the spot white needs to go is one way to look at it

ldlework: assuming each stone was the only stone on the board
dispersed: well the black dots are there for a reason..
ldlework: which corner do you like best?
dispersed: hmh
ldlework: heh
ldlework: What's the problem with A9?
dispersed: maybe intuituively H8 would be nice, but then again the G3 might be 
dispersed: A9 needs only 2 stones to capture
dispersed: so harder to protect
ldlework: Right, it's in a shortage
ldlework: Any other problems?
ldlework: Also can you see how Go is like Philosophy?
dispersed: you can't extend to many directions
dispersed: heh
ldlework: It's not taking any territory!
dispersed: isn't it taking that 1 square?
ldlework: No territory is empty space that only you surround.
dispersed: oh ok
dispersed: yeah I was never sure how it's counted
ldlework: Here's the simple algo
ldlework: start from any empty space
ldlework: moving only orthogonally, can you reach only 1 color of stones?
ldlework: if so, you are territory for that color
dispersed: true not hard to understand, just not sure how it's scored
ldlework: This means territory only REALLY exists when it is fully walled off
ldlework: But we talk about stones that are not fully walling off territory as "aiming at" territory
ldlework: H8 is aiming at aleast a few points
ldlework: Compare to D4
dispersed: what if you had A8 and B9 as well?
ldlework: it still wouldn't be surrounding any empty spots
dispersed: is that worth 0 or is that one stone 'eaten'

-- chat --
ldlework: by placing a white stone on the board
ldlework: you can see how no spots on the board
ldlework: exclusively reach only black stones
ldlework: every spot on the board can reach this white stone
dispersed: sure
ldlework: in the case of H8, black will be able to "seal up" easily
ldlework: Since they are so close
ldlework: So we think of the top right spaces as black's territory
ldlework: it's effectively his
ldlework: something strange would have to happen for black to not be able to defend such a tiny spot
ldlework: But the opposite is true of D4
ldlework: D4 aims at way too much
]
;AW[cg]C[

-- chat --
ldlework: white has enough room to invade underneath
ldlework: so while D4 is hopeful for a big corner, they will need more than just one stone to make it happen
ldlework: G3 is a nice balance

ldlework: yep
ldlework: called the "star points"
dispersed: maximal chaos

ldlework: let's look at the A group
ldlework: it's on the second line
ldlework: making 1 point of territory per stone
ldlework: it's not very efficient
ldlework: but it is very secure
ldlework: any white invasion underneath is practical suicide
ldlework: make sense?
dispersed: y
ldlework: look at the C group
dispersed: ez
ldlework: It's on the 4th line
ldlework: making 3 whole points per stone
ldlework: very nice
ldlework: but it's very dangerous
ldlework: an invasion underneath is possible in some cases
ldlework: B is a very nice balance
ldlework: on the third line, it takes 2 points per stone
ldlework: and invasion is much harder
ldlework: The lessons here are that, at least in the opening, a balance of 3rd and 4th line stone is best
ldlework: we don't wanna play on the wall and take nothing
ldlework: we don't wanna play in the middle, and not really be securing territory
ldlework: This is why E5 is not a good opening move
dispersed: yeah, it would be like micromanagement, or no management at all
ldlework: it violates all we've learned
ldlework: the order of the board areas
ldlework: and the 3rd/4th line balance
ldlework: one last thing to learn
ldlework: before our second game
ldlework: you remember Bugs Bunny and Dafy Duck right?

ldlework: Who has the better strategy?

ldlework: Why?
dispersed: it's balanced and the stones work kinda synergistically
ldlework: What do you mean by balanced?
dispersed: just balanced distance from the walls
ldlework: OK so daffy is gonna get some points
ldlework: What don't you like about Bugs' strategy?
dispersed: he's not going to capture any of daffy, and he has to distribute attention

ldlework: OK the point here is
ldlework: Bugs is playing fast and loose
ldlework: They are aiming at more territory
ldlework: But playing with weaker formations
ldlework: Where as Dafy is moving too slow
ldlework: Not aiming at enough
ldlework: Even though their structures are impenetrable
ldlework: This would've been a better example on a larger board
dispersed: ic yeah
ldlework: But the lesson is you want a balance between the two strategies here
ldlework: OK let's play a new game
ldlework: Any questions tho?

ldlework: Bugs, easy
