What's the name of this technique/pulling style?
So, I know there are 3 main movements in armwrestling; toproll, hook, press (the king's move doesn't look standard to me) and I know that each technique has its own variations such as low hand toproll, high toproll, high hook, flop wrist press etc. I'm wondering which technique/style or whatever is John Brzenk using here in his match against oleg petronko. I can see that he's heavily maintaining pronation and back pressure, maybe some side pressure too. What is this move called? Does it have a name? And which main movement does it belong to? I know that it's mainly used to fatique your opponent in the first rounds as John Brzenk himself stated in one of his videos. I would personally think of it as a defensive toproll or maybe a king's move without getting under the table?!. Any ideas?
