i suppose my issue was two fold, one this line had not been seen yet at the table and i likely gave him too much credit for reading MY hand as being very strong since it had been so tight and generally passive... the other thought was i very rarely play 300bb deep and if i lost an all in i would start playing very poorly at all my other tables due to mini lifetilt.

to make it more interesting, what is the bottom of MY range you would shove this turn with ? AJ ?
