Local cardroom, sickest hand I`ve ever played.

[2k7w625]

What would you do in this spot with the nuts? All-in or fold?

Cash Game, 9 handed NLH, Blinds $25/$50... Everyone has between $4.5k and $7k, Game is running for about 30min.
No reads yet, except for V9 who seems to be the live one, folded a couple of times to aggression (esp. from V1) after initial raises (that`s also the reason why I called preflop, I was quite sure he wouldnt rereraise behind. The others seem to be quite solid.)

Seat 1: Villain 1
Seat 2: V2
Seat 3: V3
Seat 4: V4
Seat 5: Hero (Button)
Seat 6: ..
..
Seat 9: V9

I hold Th 9h

Preflop: V8 folds, V9 raises to $150, V1 reraises to $400, V2 calls, V3 calls, V4 folds, Hero calls, V6 and V7 fold, V9 calls...

Flop: Qs Jd 8s (Pot: 2075)

V9 raises 850, V1 reraises all-in (i think he had about 4k left, but the stacks were all kinda similar anyways, one guy had 7k, the others all around 5k), V2 calls (is all-in), V3 calls (is all-in)

Hero?

I heard everything so far from "obv. fold" to "obv. call"...
