Grunch:
Preflop...
So I guess you're intending to fold to any 4B right? This is why your 3B is so small, I suppose? The 3B this small invites callers at LLSNL which just makes a big mess of things.
Would you be 3B to $45 with AA here?
I would have 3B to $65-75, since I want all my 3B to look the same.
I get that you're just trying to isolate. But isolation just doesn't work so well when fish hate folding more then they hate losing. This is especially true for BB who is ready to bloat the pot with trash.
Flop...
Cbet/fold 1/2 pot... yep. (You were planing to fold to a c/r here, right?)
After BB calls and CO folds, I think you could be good with any pair, but 7 is a disaster for you. You probably are best, but JT, J9, T9, 99, 98, are all going to make your life very hard. So, were not looking for a 7, methinks.
Turn...
You have $130 invested (18.5% of stack) into the $280 pot. You're not committed yet.
Now its time to soul read BB. Is he going to call you down with 99? Is he capable of putting you on QQ+? I don't think the 3
helped him much.
My feeling is that if we check here, then villain calls most rivers. So a check here means we should check back or fold the river unless we catch a 2 or a Q. 6 outs. I think we will hate life if a 7 hits.
If we think Villain folds 99, then we have to bet to preserve what ever fold equity we have left. A big bet looks suspicious since the 3
changed nothing. Its unclear to me that Villain calls here, so I'm inclined to bet 1/3 to 1/2 pot and see a flop.
Let's b/f $140.
River...
Plan to check back or fold river unless we hit a 2, Q.
Maybe go for thin value and b/f 1/4 pot if a 5 hits (hoping villain folds).
I likely call if we hit a 7, unless I get some sort of live read that changes my mind.
Spew? Yep. 8/10 pukies.
Wait for AX or better for isolating.
