I'm not sure about this 4 on the turn. If he just boated up he had me well beaten anyway. If he has QQ+ I'm now beaten but they seem unlikely given the pf limp. He seems to like his hand though. Is this a fold?

Tough spot!
How did he build his stack?
Without reads, I might call turn and call a half river bet ... there are so many other hands he could have (i.e. flush draw, KJ, AJ, ...)
I don't know if it's a good play though...

i´d like raise pre.

getting better than 3:1 this can´t be a fold. a call isn´t fine, since we wont know where we at and several draws are getting a good price and his turn range, betting so weak, is way more than a boat. i see a couple of JXhh, KQ, AJ.

my first idea was to raise , but we´re comitting ourselfs with a 11ish raise so we should just shove

raise or fold pf and this hand will play itself
