Two BB defense hands

[Wolfram]

Can somebody give me a solid explanation on why hand 2 is a standard c/r. I sometimes make that move with OESD, and I'm guessing you're doing it here because we have a gutshot + 1 overcard. But it's always a semibluff, right?

We're calling a 3bet and folding an unimproved turn, I assume?

If he just calls, we're leading turn and folding to a raise unless we improve?

I'm starting to incorporate the c/r semibluff in my blind defence play (which sucks atm) and I'd just like to brush up on the fundamentals. Thanks.

it seems like u got the idea just fine Wolfram, ur plans for later in the hand are pretty much spot on IMO

Whether or not to check-raise semi-bluff a hand like this largely revolves around a) ur own probable equity and b) ur fold equity vs THIS opponent w/ various hands in his range on this specific board. The idea i think is any spot where the sum is greater than 50%, check-raising is a winning play.

In this short summation i have probably left out the idea of how much u are investing to win how much, and how often it has to work to show a profit and whether that is reasonable against villain's stealing range on this board or not, but these two concepts are rougly the jist of the play.
