I rolled 4 numbers on the craps Fire bet and started to wonder what I should do after I rolled the fifth number. My question: Should I lay against the last number I need in case I don't make it to guarantee a higher win if I don't, but reduced win if I do? Example: I had $2 fire bet so after 5 numbers I am guaranteed $500. Assume I need the 8 for my sixth number. If I make the sixth number I win $2K. If I lay $600 I win $500 if I don't make the 8, making my win $1,000. If I make the 8, I win $1,400 instead of $2K. Is there a mathematically correct thing to do? The best answer for an individual probably depends on how conservative a gambler one is. I would probably go for the $2K with no hedge bet. Thanks in advance for any replies and/or comments.
