A 97 can raise because maybe it is possible to break an 87 and still another player to knock out should the 97 be good

Auto-zone, why do you think button is supposed to bet 100% here.
As a follow-up if we assume button is betting 100% is sb checking 100%

oh ok, i reread your other post and it makes more sense now. i failed to take into account predraw ranges.
this actually leads me to another question about a similar 3way spot i keep finding myself in. i have 2357 vs co and btn, 2nd draw goes 1, 2, 1. i brick. i check turn thinking the other d1 will bet, but they still don't despite cc'ing pre. is this a spot i should bet if i'm not sure they'll do it for me?
i could be overvaluing my hand... i'd like to run equities but don't know how, being they get 2 draws and i only get 1.
this really opens up a whole new world to me in terms of balance as the first d1. seems like a sick spot for the d2 to c/r the field also.
