congrats on the 4th place finish. I have won 2 of them and placed second in 1 and cashed in about 5 or 6 more. I play super aggressive once i get to the final table because everyone just wants to move up a couple bucks so they only play premium hands. and if they do have a premium hand that is incomplete like AK or AQ they almost always check fold the flop if they miss. It's real easy to take advantage of. You don't always need to go all in to win, a raise of 3x BB preflop is pretty sufficient to take down the blinds most of the time. and if someone comes over the top it's an easy fold unless you are getting odds
. try this out next time you make it this far and see if it helps. Gl on the felt.
