For money, his point of last take would be 6 pips down*, so if we were ahead by 6 pips he'd be at about 22% to win the game. Linus's takepoint AtS is 18%, so  at 2% per pip, he could still take with an 8 pip deficit.

We are up by 18 pips in the race.  This one ain't close. Ship it and see if he wants to play this game for the match.


*Using the trice count - subtract 5 from our pipcount, divide by 7, round down. (47-5)/7 == 6

Diane,

I'd like to roll out all the recent decisions, and it would be a lot easier if i had the .sgf file instead of setting up each position by hand.

So, please post it as soon as it is convenient.  thanks.

at 92% GWC, it's pretty clearly a double/pass.
