Check Raising Alternatives

[Maalox149]

Awhile ago a read a post by Jason Strasser, a great post i might add, about maximizing your profit when you have a strong hand. It advocated check calling/leading on the turn or leading on the flop as opposed to check raising. I've been thinking about this post, and I was wondering what you're supposed to do if the shoe is on the other foot.

What if you're the one who flops a medium strength hand and raised PF, and an opponent leads into you?

Or similarly, what if your opponent check calls on the flop/leads the turn?

I've been in this situation a few times myself and it is very confusing to try to deal with. It seems in this situation that the lead bet or check/call/lead is VERY unlikely to be a bluff, or a bet with a medium strength hand, as you are leading into a raiser. Is there something I am missing here, can/should this bet be made with weaker hands than sets, 2pairs etc?

Thanks in advance for your time.
