For a hand like 6789 I don't really understand why the ds version is that much stronger then the non suited version. The only real benefit of the ds that I see is if you flop a str8 and flush draw. In that case the suitedness can act as blockers and give you a small amount of value. I don’t see any value in the flush draws with out the str8 draw and if you flop a str8 and flush draw and the flush completes I wouldn’t think your hand is that powerful.
Examples:
You get in MP. You limp and the flop is , and someone in EP pots. Easy fold right?
You get in MP. You limp and the flop is . You pot and someone behind calls. Turn is a . Now what?
Am I missing something?
