I'll give it a shot, grunch-style.

1) Folded to you in MP3 with QTo vs unknowns in the blinds. Your action?

Fold. ~80%. I would rarely play this in middle position, let alone open with it. With unknown blinds, and two more to act, it's asking for trouble.

2) Folded to you on the button with QTo vs. loosish blinds?

Fold. I'm only 50% sure here. My second thought is to raise. I guess I don't know what the equity of raising here is. Limping is the last thought to enter my mind.

3) A loose player limps in UTG+2, and then it is folded to you in the SB with... you guessed it, QTo.

Raise, isolate the fish, and pound away. I'm only 50% sure of this.

4) A player with a VPIP of about 25% open-limps in MP2, MP3 folds and you are in the CO with loose blinds behind.

Limp. 30%. really don't know...

5) You have QTo in the SB, and an aggressive player on the button raises after it is folded to him. (I assume this is an easy call on the BB)

fold. I might defend if this were suited, but I'm not sure. 30%


I gotta admit, questions like these make me feel clueless, but hey, I know from experience that learning can be painful!
