i disagree. there is no proof that the opponent is holding a q. just because he bets on the flop doesnt mean he has top pair.

it was a good play raising the flop, this way you protected your hand and represented the q. then you also bet the turn, which was good for the same reason.

i dont know if checking the river was the best play though. if villian was willing to call you down to the river, he probably would have paid a bet for the showdown. being that he stopped showing aggression after the flop, you very well could have had him beat. maybe he had something like A6s or 88.

also, if he did in fact have the q he was obviously scared that you had maybe 2 pair or had him outkicked or something. in this case, checking the showdown made it absolutely impossible for you to win the hand. even if you were beat by the river, betting at villian might have caused him to fold the best hand. if you were beat, then you would be making a 1bb bet to get him to fold in order to win 6bb (that is definitely a feasible ratio).

agression is always the best strategy. but just make sure you conceptually understand the difference between aggressive and loose. not will cost you heavily.
