The original raiser had called 5 out of 7 3bets, but is pretty straightforward post flop (75% fold to cbet and 1 check raise with a set). I expect player 5 to be pretty straightforward too. Player 9's flat surprised me. I'm in 4th with 13 left, and he is in 5th. He will bluff at pots to take them down and is not afraid to get his money in the middle.

I'm curious how everyone would approach this hand on the flop in a 4 way pot deep in a tourney and what your plan is on future streets. I feel like I almost always have the best hand but don't love getting it in here.
