Binds 50/100. i raised 99 at MP ($20000 stack) to $300. Hijack,co and button calls( they have me covered).

Flop T s T c 7d,

i check and hijack bets $700. Everyone folds and i call. Hijack is an extremely tricky live player that take super weird lines. He is definitely a smart player that has an exploitively approach to the game. I haven been doing anything right vs this player for awhile and he has been making my life miserable in position. Have seen him done some crazy stuff b4 for sure.

Turn 7, he bets $2400. I'm not sure if i'm being too stubborn here on the turn and i'm pretty suspicious about his sizing too. i Have two 99s which are pretty relevant blockers to the board and i don't really feel he has much Tx in his range. 

River bricks a trey and he bets $4500. At this point it seems like i'm on station mood because like other showdown bounded live donkeys, i felt pretty obliged to call. He's aware of how ranges works and he is capable of turning weird hands into bluff. I could foresee myself to call and see some Kings and Aces as well too. Pretty much hate my life at this moment and i hate all 3 options or calling/folding/raising. Just did a river raise bluff and got called a few hands prior to this and he knows i'm capable of running river bluffs. Should we bluff our 99s relentlessly and punish him for thin value betting (qq/kk/aa/7x), turn on station mood or fold our hand and move on with life?
