Button VS Big Blind. - Page 2 - MTT Poker Strategy - Multi Table Tournament Poker Forum

This is cool and all but you're missing the important piece of information (which most seem to be missing) and that is that he's opened to 3.3x on the button.

Now if you don't play live a lot you may not know this but when someone (weak player) usually opens to 2.2x and then goes 3.2x there is a reason. In my experience that reason is because they have a stronger hand than usual but not "too" strong in their mind so they raise a little bigger to discourage calls because they are ok with winning pot right there.

Ask any weak player the hardest hand to play and I bet most will say TT-JJ and AQ/AK.

So using that information I have ATo as a huge loser shoving as his opening range is pretty strong IMO and def not opening 53% at this sizing.

Good point. His raise size changed from 2.7x to 3.3x that might be the tell that he has a good hand which he does not want to play post flop (1010,jj,ak,aq) that's why he raised bigger. I think I missed this point, therefore I just shoved on him hoping for a quick fold.
