9x9 Game - 30k vs 24k

[Mahiraku]

I was black and my opponent was White. I had played this game at beginner level and he was a 24k. I'm wanting to know what moves I could have made or what mistakes I may have made.

Move 11: You have to save the stone at E4. If white takes it all his stones are connected (therefore strong) and yours are split in two (therefore weak). That one stone is huge!
Move 30: Nooo! If you'd saved that stone all black's stones on the left would have died!
Move 39: You can always choose to fill instead of making a ko threat, so there's really no reason to avoid the ko. In this case the ko is actually still alive, since white can double atari at G7 and the only way to save all your stones is to win the ko.
Move 45: H3 would have killed white's right hand stones.
Move 48: White also has D2 now.

Hmm... I see. I guess I should have looked at each of those instances and tried to look for better alternatives.

Weird, cause it was up earlier

It's still up for me.

What browser are the people who can see the game using? I've never been able to see 9x9 games on the eidogo plugin.

[Joaz Banbeck]

I'm using Firefox 23.0.1, and I can't open it.

It no longer works for me and it appears that the file has been deleted so I'm wondering if the reason it worked for me when it didn't for others is that my computer was loading a cached version.

[Mahiraku]

Maybe. I can try and fix it

Update: Fixed for now.

should be at E4

must be at E3, that capture cannot be allowed.
