first, welcome to the site!

thanks for posting. i moved the thread here, as this is where all discussion of hands/strategy happens. unfortunately in moving the thread i lost the response given by JDOG, sorry.

as to the hand, i think limping the 99 in early position with that stack is pretty bad. there’s just no way to balance it without spewing–limping stuff like suited connectors and folding to a raise–so you’re better off either a) raising with a plan or b) shoving.

after he limps and it’s folded to you on the BTN it’s hard to say for sure if the shove is good or not without any reads on UTG+1. has he been limping a lot, or had he generally been opening pots for a raise? was he tight? loose? all these help us to assign him a range afterwhich we can better answer whether or not the shove is good.

in general, with effective stacks of 17BB, i think the shove is fine.

with 7BB, unless theres like a raise and four shoves, you should never be folding TT. just unlucky.
