On the first hand, you're thinking along the right lines. I think this
spot is fine, but just remember to be careful with multi-way bluffs where you
don't have much
equity if called because you need so much more
fold equity to be profitable.
On the second hand, your
bet size is too low. You can easily be betting at least $0.90 here on such a
wet board against this guy without changing his
calling range much at all.
On the third hand, your head is in the right place, but the way you describe it is a little wonky. You can probably
value bet your hand here and have him
call with a
range that you beat just because his
range is so wide and the
flop is so dry. Value betting with a hand that might not be
ahead of his
calling range isn't accurately described as turning your hand into a
bluff if you aren't expecting him to
fold better hands ever. Checking is likely the best play here because of how wide his
range is and how aggressive he's likely to be. Basically, you get him to put in more money with a weaker
range more often when you
check than when you bet. He's going to bet a wide, weak
range into you, etc.
Overall, these are some good applications of what we've been talking about.
