I understand what you're saying but I do believe enough information has been collected. It's a close spot without any info so only 2 hours (~50 hands) of info can sway someone's default/no reads decision from a shove to a fold. I really think the most important factor is that he only started with $200. This tells me he probably is not used to playing deepstacked and would not risk doing this with anything but AA and I'm 95% confident in that.

Also, my default move with no reads would be a fold (although sigh and shove 100bb deep) because of my experience in these situations with old men who limp raise.

Hoodie gets the click it back min4 bet shoving inducer every time.

And I might add that if the "old guy" is one of those rare guys that has shown spewy aggro blurts of betting (even in just one round), then I give him the shove too.

When the little old lady school teacher sits down and limp/3bets pretty good utg, I am so disinterested in KK that it is pitiful.

Bottom line is this. There certainly ARE times in live poker when we can discern a players range to be EXACTLY AA. Which is why in my opinion Dan Harringtons theorem (in his book) of never folding KK preflop is incorrect. This is a game of ranges, and sometimes the range is .....AA......and thats it. So now its up to us to figure when that range is this narrow. It does exist, I can promise that.

Dan most likely felt it was safer to give the no fold answer which could foul up the majority of players who would attempt folding KK in all the wrong spots. I dunno.

Easy fold.

Oops misread your hypothetical question. Shoving on both them since they are both new to the table with at most 100bb. This Old man would have started with $200.
