Largest group you've killed

[Monadology]

So I was just in a game where, due to no real virtue of my own, my opponent ended up with a group of 48 stones with one eye completely surrounded by my own living groups. The upper left corner may not be alive, but I'm pretty sure it is. He left the game, so I didn't have the chance to mark them dead or place the finishing stroke.

This thread is for posting and recollecting about the largest single groups of stones you've managed to kill.

My own group or the opponent's?

This is recent, but I don't know if it is the biggest:

Not exactly to topic, but the largest group I sacrificed (and still won the game) had 15 stones (the same match had another 5-stones-group that I sacrificed). It was the last match of the 2009 St. Augustin tournament 10 months ago..

Counting only serious games, I think the following game contains my biggest kill (see last move):

Also probably the end position is the largest margin I've ever been ahead in a serious game

My own group or the opponent's?

Either.

Wow. Did it surprise your opponent or was it the only viable option for them to take it?

Well, he seemed too focused on capturing that group, and while I chased his capturing stones (by threatening to pull the dead group out of his claws) I made a huge territory at the edge that outweighed the lost group by far.

This is the largest capture I've made so far, during a 7-stone handicap game against a 3K player last weekend.

It wouldn't have been such a big capture if my opponent hadn't kept trying to save them. Originally it was just a 5-stone cut (though black's profit in territory was significantly more than 5 stones). I guess white was thinking I would make a mistake somewhere and he'd be able to live, but all I had to do was keep my groups linked up and safe and attack any eye space he started making. The more he fought, the stronger black got.

He worked hard to connect his weak groups. It really looks like a handicap game that's gone south for white, eh ?

[Dusk Eagle]

Back when I was 8k, I played an even game vs. a guy whose fuseki seemed pretty okay. Then he made an odd move. His frequency with making odd moves increased over time from that point on. He would try to break his stones into my territory, but he was completely neglecting the concept of eyes! It was like he had learned all of Go except for that one p critical part. After killing a couple more of his groups I decided: everything must die. Which it did .
