I dont know if you guys would go betting out, on flop and turn, but with hitting top pair on flop and flush draw on turn and since no aggression was shown from utg+1 &amp; , MP so i think i could have had the best hand.

The fun began on river, when i hit my flush...
So my question is one on my flop/turn play and another on river...

i guess its pay and expect what???
