Hi guys

First: There are some mistakes in the HH. I think it's because I've stopped action at villain's turnbet to avoid you guys getting biased. I open, villain calls. I c/c flop. Villain bets turn. We're 100ishbb deep.

I don't know if it's just selective memory or a bad composition of my range, but I feel I'm being exploited in my c/c ranges in spots like this. At least I feel I'm open to being exploited, as I think my current c/c range is somehow inferior, leading me to fold too much.

How would you guys compose a somehow balanced c/c range in a spot like this? And what are your thoughts behind your chosen composition? Any particular factors you weigh more than others?

Personally I feel I'm lacking arguments, so I hope some of you guys will start the discussion, thus we can get a good discussion going.

Thank you in advance,
WHPH
