I know that if I reraised before the flop this didnt happen.
also I was thinking about reraising on flop but my plan was to scare him by calling and then to reraise on turn.
when he betted so much on turn, I put him on AA or a J. AA: he maybe tried to lure someone all in by raising so much PF, he dont raise 5BB normally
