Two techniques. For the first, the text does not match the drawing. You are supposed to strike away his stab with the right hand, but in the drawing, it's him who has a hold on your right hand. My interpretation is that this is a counter to the defence we saw in plate 172 and various others. He has set aside my attack, so I throw my hand around his neck, enter behind him and throw him over my hip.
The other technique is fairly straightforward; catch the thrust, turn, and break his arm on your shoulder.
