Blue(Montenegro) judoka with arm triangle(choke) in place, escaping from half guard.
Blue in side mount, with arm triangle fully applied, White taps. Ippon for Blue!
I do wish that in sport judo nowadays that they did let the judokas show more ground work. There are so many opportunities for different submissions that the officials don't let develop. In the case above, Blue was trying to sweep White to expose the back and get points, but switched right away to the arm triangle.
