I was wondering about that gutsy hold myself....thought, "man that guy has balls of iron holding a pike like that". But if the fish was in mid-flop I can see it. Your murder scene look-a-like in the boat has been a part of every angler I know who's dealt with large pike. Those teeth are not very friendly.
Nice fish bud! And forget mud. Use slime from the fish...its a natural coagulant.
