I think you're getting greedy.

If you're unsure of your hand then check/call.

If you like your hand, then bet it and be willing to pay off a raise.

But I see little point in check/raising. Mainly, because a worse hand probably won't bet. If a worse hand does bet, it probably won't call a check/raise. Either way, when you check and your opponent bets, you become a bigger underdog when calling, so check/raising makes even less sense.
