in the silver article "Before the Flop - When There Was a Raise Before " there is a hand explaination: "SHORT-HANDED OUT OF POSITION" in the first page, where UTG raises, CO 3bets, hero is in SB with QQ.

And there is "what if..."
…UTG had the stats of (13/10/2.1) and CO the stats of (20/16/3.8)? UTG's range could also be very wide from early position, and against CO's 3-betting range you are also ahead most of the time. Here you have to 4-bet and go broke.



What do you think the CO 3beting range is in there? I think it is narrow, because he sees that UTG is tight, UTG could raise with AQ+,TT+. So the CO would raise with like with AK, QQ+


Equity Win Tie Loss Hand
Player 1: 11,454% 10,572% 1,905% 87,523% TT+, AQs+, AQo+
Player 2: 51,819% 51,316% 1,145% 47,539% QQ+, AKs, AKo
Player 3: 36,727% 36,207% 1,181% 62,612% QQ

So we are behind there.
