My doubt is in the flop, the reason why I raise preflop is for obtain a free card in the flop, then I bet the flop after his check , when the plan was check behind and get a free card, I was lucky on the river, but is my line ok, of course after his raise in the flop i think i'm commited with my 9 wrap outs.

Is all this standard or should i check behind on the flop?
