Preflop Calling Ranges question
In one of the articles on cardschat I read the following:
Suited broadway + offsuited broadway: In the same vain as suited connectors I will frequently flat all suited broadway in position. I will do a lot of floating with pairs and backdoor draws, I will often raise continuation bets in position when I flop overcards with suited broadway. So for example, cuttof raises preflop and I flat QJs on the button. Flop comes down 278 with 1 of my suit, this is a great spot to raise a continuation bet.
Can someone explain why you should raise continuation bet in that case?
