Low Stack: Pocket Pair, High Stack: Suited connectors. From my experience, there are better possibilities, when playing suited connectors. I have to fold pocket pair very often, because of straights, Overcards, flushes,...
I personally prefer suited connectors, they have gotten me out of many sticky situations. Some pocket pairs are great to hold preflop, however depending on the how the preflop bets etc has gone I definitely prefer suited connectors if it's a juicy pot.
It all depends on the type of tournament, the rate of growth of the blinds and the players at the table. In short, pocket pairs are good for pushing all-in if, for example, the blinds are growing fast or you have a short stack and suited connectors are good for playing.
I prefer a pocket pair because if it flops well it's already a strong hand, whereas if a suited connectors hand flops well it's a hand that still needs some improvement to become a strong hand. And as we all know this improvement might never come, but it still requires some investing. So I prefer a better risk/reward ratio, hence pocket pair. But I do play a lot of connectors though, I mean way too much, actually
The pairs of hands made in the pre-flop game are better to play and try to gain an advantage over your opponents and more if they are high like QQ KK AA the strongest, but if they are low you would seek to be lucky and connect a three of a kind on the board. .
Personally, I like to play connector suits more, but more when I have a position on my opponents and it is good for me to play with those connector suit hands.
I guess it depends on the stages of a tournament or the game been played, but I agree with what others have said. High pocket pairs over low suited connectors and high suited over low pocket pairs.
It's not that i follow any strategy as I mainly play for fun, but that sounds about right and what I would be playing most likely for sure.
Of course, top pairs are always the best and safest choice, as they will win most of the time, however, in some tournament circumstances suited connectors are a great hand, but you need to know how to play with them and make the best use of them
