PhiNotPi

02:06

I want to figure out, computationally, what the best "minimal opening repertoire" is for both sides.

The core concept is that, although the best move in any particular situation may vary, there are often whole categories of positions which share a common "good move."

Hosch250

Hi.

PhiNotPi

hello

Hosch250

What do you do when you feel like you can't get any school done?

I have several papers I need to write, and I'm having trouble making myself do it.

Oh, feel free to move these somewhere else.

PhiNotPi

procrastinate until the last possible moment?

Hosch250

Yeah... I need to write them--it is almost the last possible moment.

I keep reading, playing chess... Anyway, time to wash the dishes.

Let's see if I can't set a goal for myself tomorrow and keep it. One assignment ready to submit, and another with at least one page written.

6 hours later…

@PhiNotPi If anything, do not play Sicilian.

08:59

Oooh, nice one.

4 hours later…

El'endia Starman

12:40

Nfg4 seems like a decent move for Black.

1 hour later…

bwoebi

13:54

I would make attention that the queen actually can evade here when it's going to be attacked

Nb5 incoming

blocking the b line and covering a3 as well as the bishop on d4

ah I see

The bishop is going to be attacked with chess upon Nf3, which one cannot take with pawn [followed up by Qxh2]

And if we take with queen, we change bishop against knight

which is quite a bad choice

bwoebi

14:22

yeah, Nfg4 is probably the best move …

PhiNotPi

15:13

My main concern is 16. Nb5 17. Nc7 for a fork.

Actually.. that's not much of a concern, I don't think.

Actually it probably is... since Nb5 will protect against Qxd4, which would cause black to waste a turn saving his queen.

So black should try to do something right now to prevent that

El'endia Starman

15:46

Oh dang, that's definitely a threat.

15. ... Qb4 16. ... Re7

Adnan

Nfg4 looks very decent to me

You don't want to lose the initiative with black here

El'endia Starman

Aye, but there's a serious threat facing Black.

Adnan

Oh, you mean Nb5?

PhiNotPi

yeah

Adnan

I think you can take out the bishop with Nf3+

Which would also bring out the bishop to the game

PhiNotPi

15:58

I suggest Kh8 to complete the diagonal.

Adnan

hahahaha

Geobits

@Adnan gxf3?

Adnan

@Geobits Bxd4

Geobits

Oh, so the f6 knight has already been moved?

Adnan

Yeah

Nfg4 actually threatens Nf3+ in almost any case

Geobits

16:02

You'll lose the rook if you take the bishop.

nvm

Adnan

:P

Geobits

Forgot about the check ;)

PhiNotPi

so... what's the plan now?

Adnan

make a counter threat with Ngf4

PhiNotPi

So we do Nfg4, then what would white do? Then after black does Nf3+, white could recapture with the queen.

Adnan

16:10

Hmm, yeah, we should probably calculate every option for white to make sure

PhiNotPi

So we're thinking 15... Nfg4 16. Nb5 Nf3+ 17. (either gxf3 or Qxf3) Bxd4+

Adnan

15... Nfg4 16. Nb5 Nf3+ 17. Qxf3 Bxd4+ 18. Kh1 Rxe1+ 19. Rxe1 Nf2+ 20. Kg1 Nxd3+

So, Nb5 is not a good move

PhiNotPi

which is good, I guess

Adnan

for white, yes

PhiNotPi

for black?

Adnan

16:16

Oops, I meant black :p

bwoebi

@Adnan solution: Be2

Be4 is dangerous because f5

@Adnan yeah, if you play correctly, I see no way for white to play Nb5 … but make one inaccuracy with black and your queen is at risk

Adnan

Yeah, it's a position where you need to be careful

I do think black has an advantage here though

bwoebi

it mainly has the advantage of the pawn

I do not see white destroying black here

Adnan

Not necessarily destroying

But a positional advantage

bwoebi

@Adnan no long term one. white probably will have to exchange some figures to escape here

PhiNotPi

16:23

black's queen position is pretty awkward

bwoebi

@PhiNotPi well, it's quite normal given that it hasn't been moved yet :-P

PhiNotPi

??? I said black's queen

bwoebi

ooh

yeah… I last time made sure that blacks queen cannot come to Qb2, but something must have gone wrong in the meantime

Ah, this Re1 move

PhiNotPi

RIP Hosch

Hosch250

Oh. So that was a bad move?

bwoebi

16:31

well, it was the move allowing Qxb2 ^^

Hosch250

@bwoebi I did that move.

bwoebi

yep, I saw

But one cannot see everything

But uh

It actually doesn't have changed anything

I made the mistake a bit before

PhiNotPi

@Hosch250 Moves aren't good or bad, just different.

Hosch250

Queen to b4 looks like the only way of escaping.

Then, she can move at a diagonal back behind the lines.

bwoebi

And why would you want to escape?

Hosch250

16:34

You don't want to trade a queen for a rook?

bwoebi

[ProTip™: read the backlog]

2

PhiNotPi

Speaking of which, our plan above for Nfg4 Nf3 etc. would allow for Rxe8+

bwoebi

@Hosch250 sure we don't

Adnan

@PhiNotPi Nf3 is check

So we can do Rxe1 first

if necessary

bwoebi

Nfg4 Be2 …?

Hosch250

16:36

OK.

I definitely wouldn't recommend knight to b5 just now.

The queen could just take it.

PhiNotPi

One of the main points to the Nfg3 Nf3 plan was to allow Bxd4+ but if white can find room to play Rxe8 in there, then black is down material.

bwoebi

@Hosch250 [the pawn protects it]

@PhiNotPi white doesn't get the time … I suspect there will be a very quick checkmate otherwise for white

Hosch250

Ohhh, I was thinking white was moving the other way.
