This is more of a linguistic question. There will be mats next.

минимум 12. Если первый будет подыгрывать, то 165 максимум.


I got 12, too.

Who wants to play? ;)

There will be further discussion in the traders' forum. Adnatyna. ;)

 
vegetate >>:

минимум 12. Если первый будет подыгрывать, то 165 максимум. Хотя не, даже все 210.


:))) It's not!!! The answer has already been recorded!

 
MetaDriver >>:

У меня тоже получилось 12.

Кто хочет сыграть? ;)

Few.

 
Mathemat >>:

Мало.

Then I can play as a minimiser. Show me how bigger. :)

// You can play in just two posts (with edits), it won't take up much space.

 

There is a very simple strategy that allows the second one to be guaranteed to score at least 30. Shall we think about it - or should we show it straight away?

 

10

+1 -2 +3 -4 +5 -6 +7 -8 +17 +9 -20 -19 +18 +16 -15 +14 -13 +12 -11. .

--

= +4

--

// Think about it.

 

OK, mine is blue then (boom in these two posts?):

+1 -2

+3 -4 -corrected, pardon

+5 -6 - (so, already at least 32 in the pocket... was ...) Driver, areyou cheating too, or what? Or is it me playing Caesar here (reacting on three fronts)?

+7 -8

---- swapped, now my move is first (aim to make the module no more than 30, or better less)

+17 +9

-20 -19

+18 +16

-15 +14

-13 +12

-11

10

(Sum +4)

By the way, you don't have to put the signs in order. Try somewhere in the middle, it's easier to understand what I'm doing.

I guess you know where my big move is going to be. When you put the sign... say, where? Or let's swap? When I'm first, you'll have a strategy to get exactly 30.

 

Place your bets, gentlemen.

Un quid on the drivers.

who's up for it ?
