Hi Guys i recently had a hand in a 5/10€ - 9 handed casino game that i keep wondering if i played it correctly. Guy raises 40 preflop and i call from dealer with Ad7d8c10c; with a 2200€ stack behind me, 3 other players call also.

Flop comes Jh10d8s - raiser bets 120 into the pot and the 2 other players call i procceed to call on the dealer.

Turn comes makes the board Jh10d8s9d - raiser checks, player 2 checks and player 3 bets 620 into the pot; player 3 is a complete donkey and an awful player i think he most likely has a higher straight then me but i choose to check as i have position.

River makes the board Jh10d8s9d8h and player 3 goes all in for 1600€ instantly and i insta call getting scooped when he shows JJQ7 - What do you think about my insta call? is it a very bad move considering player 3 is an awful player - what would the optimal play for the hand be in your opinion? thanks alot :)
