This hand should never raise over a limp pre flop from mp. Given multi way on the flop on an AA4 2 spade board yo should be betting around 40% pot, because people don't
bluff multi way and you want to try and build a pot with your nut flush draw.
given the check on turn you should make re raise sizing much bigger than min to about 660, This way you have a lot more
equity realisation as his range becomes more defined.
however given villians bet on river and the line we took, we really cant put him on a range and thus fold is the best play.
