Oh my goodness.
A poker analogy would be to say you have committed 2500 to a pot. You have 2500 left. A guy guys all-in on you with JJ and shows you his cards.
You hold AQ.
Saying "I will lose this one over 1/2 the time, I'm foldin.........I'll just use my remaining chips to wait for better situations". That obviously isn't gonna get it done.
If you prefer the 2500 Bonus Play over the 5,000 in expectation, then I'm afraid you and I are going to have to agree to disagree, as I seriously doubt we will ever agree on things, if we cannot see eye to eye on what I believe is a total "solve by inspection" problem.
A better question is make the stakes your ENTIRE bankroll. You are broke. You can take 250,000 or have a free 500,000 bet. I'd STILL TAKE THE chance, fyi.
I find guys with small bankrolls who are unwilling to take chances like this blame the small bankrolls for having to turn it down. The opposite is often true. THEY HAVE SMALL BANKROLLS BECAUSE they ignore great opportunities like this.
