A Hayemaker bet and a Tyson question

Hey guys, I have a couple of questions that you're sure to be of great help with, and rather than starting two threads, I thought i'd jam them together to save space :) Firstly, i've never layed a bet on before; not on anything, but I feel like trying some out this Saturday for Haye's outing against Barrett. Basically, i'd like some input on my bet ideas (whether they're feasible, correct/worth it, how to go about asking for them in the bet-shop), so here they are: 1. a bet on Haye winning within 6 rounds. 2 a bet on Haye winning by stoppage in the 5th round. 3. same as above, but round one. Secondly, I was utterly bored at work the other day and had a random thought: in a professional fight, was Tyson ever (legitimately) put down by a punch/combo that wasn't the punch/combo that ended the fight? I can't recollect him hitting the canvas and getting up to win or lose the fight; if I remember correctly, every time he was put down, that was the event closer? He was dropped by Lewis, though that wasn't legitimate as he never touched down (it was ruled as one, though, so maybe thats the closest there is to him dragging himself off the canvas). Against Lewis and Williams he was pushed (not knock-downs), and in his KO losses (Holyfield, Williams, Lewis etc) I don't remember him going down prior to the KO? My memory is terrible at best, so forgive me if i'm wrong, but yeah, any thoughts?
