Risky isolation move and a SB vs. BB hand

[bmxreed36]

Ok, first hand is a $10 freezeout, about 150 left with 99 paying and I'm looking to get a nice stack as we move to the bubble. First orbit at the table so new reads except that the shorty who pushes had just lost a big pot and could be movin in with a fairly wide range. If I isolate successfully here, I'm getting awesome odds so the question is, how much fold equity do I have? Is this working enough to be profitable?

The next one is the FT of a 20/180. If you'll look at stack sizes I'm in good shape and about to tangle with the only stack who can bust me. The reason I didn't raise preflop is that I had raised the last two time it folded to me in the small blind and since he seemed somewhat aggressive I felt that he may be able to reraise with less than a better hand and I didn't want to create that situation. Also, by limping he may not give me credit for an ace if I do hit the flop. So what's the plan for this flop? In the actual hand I bet 6k and he pushed. Easy call? Tough fold?

First hand: The tornado is trying to snatch you up. Run away, my son.

Second hand: Would have raised pf. As is, fold.

Why the overbet on the flop on the second hand? Looks weak. May have encouraged the villian to bluff you.

Hand 1 - While I like the idea of the isolation, two other players makes me want to fold this.

Hand 2 - I suck in these situations. I think I'm going to check and plan on check raising any bet. As played I think you have to fold, even though his bet feels like a 9 or 5.
