It's pretty simple.
Stick to a bet, say $50.
If you lose, now double your bet to $100.
If you win your second hand, return to normal $50.
Everytime you lose a hand double your bet and continue, that way you'll just need the one win to get you out of the hole.
Disclaimer: If you go on an unlucky streak and continuously lose multiples hands in a row while doubling your bet, leave me out of your suicide note.
