Was I right to make this call? Was I lucky?

LOL - well imho you did everything wrong.

I wouldn't of even entered the hand.

To call the original bet you need a decent hand - and 7-7 isn't good - your just asking for trouble with these types of holdings - most of the time the flop will come with an over card or two - and you just won't know what to do with your holding.

Having said that when the flop comes you need to bet on the first round to see where you are - i'd thought my opponent having raised the flop probably wouldn't have a j or 10 - although he could well have a holding of two over cards - in which case he probably won't get scared out too easily with a gutshot straight and two overcards - his AK maybe better than your AQ for example.

I would of probably bet just over half the pot to see where i was standing - but i wouldn't of had the problem in the first place.

Judging by this play i would say you were a novice player but lucky!
