I do not believe making a deal is part of poker.
You are also free to believe the earth is flat or the 2+2 sometimes equals five...
"I don’t like deals, but make them
when (for one reason or another) I get the best of it. A few years ago I played a Limit Holdem tournament at the Bicycle Casino. We were three-handed, and I was in trouble. My two opponents each had forty chips. I had twenty chips, and I had to put eight of those chips in on the big blind. Then like a gift from the gods the player on the button said: “The limits are pretty high, why don’t we just split the money three ways.” Before I could say anything (like... “Yes!”), the other player said, “Good idea.” One nanosecond later I agreed, and I was giddy for days afterwards. My opponents were not god-awful players, and even if they were, I had a two-to-one chip disadvantage and I was being forced to put 40% of my stack in on the blind. There is no way I will turn down an opportunity to have so much the best of a situation. I got a share of the first place money. That is what I came there for."
Note that there is a difference between ICM and Stack Size Ratio deal pay outs:
"Compared to the fairer ICM method, Chip Ratio tends to give too much to the larger stacks at the expense of the smaller stacks. The two methods are equivalent for a winner-take-all tournament, but not for tournaments with multiple prizes. In fact, using the straight Chip Ratio method without any restrictions can result in highly imbalanced payouts."
