I agree with Stephen, suited connectors are not hands you want when playing heads up. People with decent hands heads up are more likely to bet you out of the pot since they're only playing one opponent.

It was also touched on, but flopping top pair is not what you're looking for, you want a draw. If I'm playing a multi way pot and hit top pair with no redraw, then I'll usually fold to any c-bet if it looks like it's going to be heads up.

Another thing you have to be aware of is the level of aggression at the table. If it's pretty passive and you have a few callers and are in MP, then I don't mind calling a 2 or 3xBB raise as you'll likely have another one or two calling behind you. If it's an aggressive table and people are betting 4 and 5xBB, then I'll only call with 76s and higher from the CO or button.

But if you're anything like me, I'll call multi-way pots with just about any hand in late position if those in the pot are deep enough. The better I get, the more comfortable I feel playing pots for implied odds, so my hand becomes of less relevance.
