We are 14 left in a $11 turbo and i find myself sitting in the BB with AJo and 20bbs (blinds are 6k/12k and i have 240k). Player who opens from the CO just moved to my table so i know nothing about him. He has a stack of 400k and opens for 3x, i jam and he snap calls with 66.
I think i was 8/14 and he was 3/14. So here are my questions:
What do you think about my shove? what about his call? is it standard? can i just call pre and then check/fold or check/shove flop?
fwiw i think his call is pretty awful but not really sure about my shove since there were a few guys with like 8 to 12 BBs.which still puts me in an ok spot if i just call pre and check/fold flop.
What do you guys think???
