Clearplay bonuses strategy

[Jim14Qc]

Hey, I'm going through the "Beating Bonuses" list (so far I've done 4 I think) and it seems like there's a lot of clearplay bonuses.

So far, the advice given by the website is to bet the full bankroll on baccarat and then take the winnings to roulette to clear the requirements (if it's in T&C, otherwise cashout). The ones I've done so far are 400% bonuses on a $50 bonus.

Am I wrong in thinking that betting $200 instead of $250 reduces my chances of loss? That way if I lose $200 in my first hand, I can then proceed to bet the last $50 (bonus money, can't cashout) and if I win I have $50 cash and $50 bonus. I then bet $50 or cashout. If I bet, I either win or re-do the same thing.

That way, I have a risk of loss of around 25% (a bit higher than that but w/e) since I have ~50% chance of winning (I play dealer, not player) on my first hand and if I lose I have another 50% chance to make my money back.

Any thoughts? Am I wrong?
