9 Left everyone in the money as savers have been done, average stack 35k, I have 42000. Blinds 800/1600/100. I'm in mid position with

and raise to 4k. Button, who is tight aggressive, announces raise, and makes it 10k, but it goes in as a string bet, and the dealer declares it a raise to 8k. He has around 20k back. Back to me.
Shove or call?
