Help to identify an interesting game

I found this on youtube:

The two player appear to be Imamura Toshiya and Murakawa Daisuke. The tournament could be NHK Cup. But I found no games between these two player in recent years. The game cannot be too old because Murakawa is young.

The game contains a rare "ishi no shita" and I'd love to include it in my database.

Thanks! I actually have this game in my collection. Somehow did not find it.

Am I sadistic if I enjoyed Imamura's facial expressions?

Why does he bother playing A15? He clearly sees the under-the-stones play by then...what does A15 get him?

4 captured white stones. It's a 3 point sente yose play.

Edit: I wrote this before Uberdude posted. It seems he counted things differently to me, but I can't see where I went wrong. I'm going to post this anyway in the hope that someone will point out my mistake.

Capturing first is 2 points better for black.

Points gained after Black A15:

White: Territory 4 + Captures 4 = 8
Black: Captures 4
Difference = 4 points

Points gained without Black A15:

White: territory 3 + Captures 3 = 6
Black: 0
Difference = 6 points

A 2 point sente is big in the end game.

Splatted, white only gets 3 points of territory when he captures 4 stones: b14 has to be filled.

Thanks I see it now.
