Hi Grant, I hope patience is the key to not getting bashed up. If I feel ones still a bit green then a bit of a prod will send him back down to the bottom again for a few more rounds. Play out the battle under the water not in my lap. When he`s played right out, that is if they ever get dead tired, time a well placed couple of dongs on the snout and when he seems to settle quickly knife him at back of head to kill him off quickly. I don`t mind a few bruises but I don`t want him knocking me out! Steve.
