Aruba main event hand

[bugstud]

Like the 6th hand of 50/100, I've played the previous 5 pots and won all 5, showing AK once and maybe TT another time, I don't recall exactly. First level of 25/50 I was kinda active but not overly so.

Villian in this hand has played one pot of note, raising 3 limpers and the sb completion 325 more @25/50, only the utg limper calling, betting 1500 on 832r flop, utg made it 4500 and he snap shoved. OTher guy tanked and folded. He has like 20kish right now. He's played a lot of pots but I haven't seen him reraise much. He hasn't shown anything down except when he was called and he had the best hand.

I open UTG+1 with KdKs to 300, folds to him in late middle and he makes it 1k, folds to me and I call.
Flop J73r, I check/call 2k

Turn 2h putting 2 up, I c/c 3k

River 8c, I check he shoves. What should I call here? Like 7k effective for me.

Call/fold range and how have I played my hand so far for some of these hands?

edit - I suck at not revealing holecards. anyway, call or not call, and do you like the line. also, one of the hands was when almost no one was at the table yet because everyone is slow getting back from break.
