Pretty early in the tournament, so no individual reads but overall the table has been kinda loose to put it kindly. I'm pretty sure that the call is good pf as is the lead, but I'm not sure about calling the all-in. I sort of put him on
A8, 99+, AJ+. His all-in sure does smell like an attempt to push me out of the pot. If he has QQ+, I see him rr me and not shoving over the top. I do see him shoving with 99 or A8 or AQ+. Good call for all of my chips? Don't risk it here? Thoughts?
