Sorry if this stuff is standard guys. I just feel like suddenly I don't know how to play anymore. So I'm going to ask even at the risk of annoying people. CO is relative unknown 22/0 over 9 hands. Thanks for help.

Shove is ok, so is fold. I wouldn't flat but that's possibly an option vs. an unknown, I guess.

[ ] minraise
[x] 3bshove as default, call his shove as default

marginal spot, might pass it up since both quite deep (for a 180man)

Why are your default lines, read-less, against unknown randoms so loose?

Are you saying that if the villain had shoved here that you would also be calling?

This would be entirely too loose and a mistake read-less against an unknown villain.

3bet shove is alright in this spot; stack setup is perfect for it and our hand does OK against a tighter 3bet calling range. Probably around ~30% equity against the range that calls our cold three bet shove and we probably get enough folds on our three bet shove to make the reshove profitable. Overall though in situations against unknowns I think it's often best to error on the side of tightness until you are able to get a more accurate view of their ranges and how they are playing.

I think calling an overshove with A9ss in this spot against an unknown random would be very spewy. Also don't really think flatting is a great option when you are forced to play the rest of the hand out of position and readless against an unknown. Flatting would be an option if you had more reads on your opponent.

Three bet shove or fold in this spot.

Thanks guys, in the actual hand I did end up 3 bet shoving and then doubting myself when he showed me AK. I guess that's what happens when you're on a 135BI downswing though, when nothing is going right. At least I know my play was acceptable. Thanks for the input.

At this limit the overall play is more passive so you get lots of +ev Shove Spots later. That means you dont have to resteal in Spots where you dont know anything about the raiser. That being said the stack setup + your Hand+ his Raisesize are perfect for a Resteal. I guess its a breakeven spot vs unknown.

what should be our default 3bet shove range here against an unknown?

i would do AT+, 99+ but for some of people here it may be too tight..

Jamming is fine due to extreme shortness in the BTN/SB
