Any comments most welcome. Sorry for keep asking for views on hands but Im struggling to learn this game

Don't make it that big preflop in online poker, especially at a fast table.

Checking on the flop is better, especially when a guy on the tight side called that preflop huge raise.

As played, I'm folding when he raises the turn, he shouldn't bluff you that often given the strength you are representing. Actually you are representing so much strength that I wouldn't mind a check on the turn either. I don't know how often this guy is calling your 2nd barrel with a worse hand.
