Suppose an eccentric millionaire is at the table. Before the river card is dealt, he whispers to you and you alone "boy, I sure had a lot of fun watching you play this hand. I gotta go right after this but just to thank you for the pleasure you provided me, I am going to give $5,000 to the winner of this pot. Good luck".

The river card is then dealt and your opponent (in exactly the same way) slides in 8 chips into the pot.

Would you have called?

If the answer in "no", then the issue is resolved.

If the answer is "yes", it simply means that the decision to call is always about pot odds in conjunction with your assessment of your chances of holding the best hand and that you were not 100% sure that you had the worse hand.

You are simply saying that there are spots where 22-1 is not enough and this is one of them. Mike l. says that too. I can buy that. But to that, I simply point out that you are operating with a very small margin of error. If you can confirm that, then I too would consider the issue resolved.

Come to think of it, I don't even need the contrived eccentric rich guy scenario to illustrate the point. Suppose your opponent made a 50 cent all in bet on the river. Would you have called? Again, if the answer is "no", the issue is indeed entirely resolved.
