I'm pretty confident that he does have a premium hand and is not bluffing. I put him on a 1010+ range (top 5%). I have about 1250 chips. There is 625 in the pot and it will cost me 250 to call. Pokerstove puts AKo vs top 5% at 49/51 in his favor, but there is already 625 in the pot.
What is the best line here: fold, call or shove?
Thanks for any input
