villain unknown, 1tabling from China

Do you just 4b/gii here vs a 1tabler? I strongly thought about it but was a bit scared away by his 3bet sizing which looked sth between reasonable and what a fish would chose with a strong hand. So in the end I decided to just flat in these positions.

Again, kinda unsure what to do here. TT, 99 outflopped me even though he probably doesn't have either often at all. I felt like I should protect/get value from his AK and other broadways as well as FDs which are probably going to check back the turn a lot given his weak sizing. I'll still lose a stack vs KK+ but can't see what I could do about it.

And again lost for the 3rd time. :D We have roughly pot behind, I can't really see him having Tx unless it's specifically ATs or sth he splashed around with preflop but what is going to call me now if I shove? It might still have merit though because he clearly doesn't have KK+ anymore and this way I can protect from the few FDs/overs he might have, but I really don't expect to be in decent shape when called. Any suggestions?
