Hand 2: NYC Live 200/400 vs TheTakeover

[rock1]

villian 1 in this hand is Nick Shulman, still playing very solid...villian 2 is Artie who plays very aggressive, and is very tough to play against out of positions...Artie is stuck big in the game and definitely chasing to get back to even...the hand is 25-50-100-200-400...i start hand with 45k and both villains cover...their read on me is probably on the tighter side preflop with lots of very aggressive play postflop...

folded to Nick in the small blind who makes it 1800...i call from the second straddle with AdJd...Artie calls from the last straddle...

(~6000) flop: Qs Js 6h...action gets checked around...

(~6000) turn Jc...checked to me and i quickly bet 3k...Artie min raises to 6k...and Nick check raises to 16k...action is on you, whats the plan here? After much deliberation i decide to call...Artie folds...

(38k) river 4s...Nick thinks for a long time and bets 37k...who calls and who folds in this spot?

this hand may actually not be as interesting, but i'd like to see comments
