Replay Overview:
Dynamic grips pin pressure: For sure some dynamic gripping, but you guys may not count this as pin pressure. I think it's logical to use this replay for both techniques.
Slam: Yep.
Hook: I usually don't do what I did to get this hook in. My opponent made my forward momentum raise him high, and since I had a more stable base than him, trying to lift me up on made his feet slide off the floor. I wasn't trying to do a lift kick, I promise! Regardless, the hook is clean.
