Max vs Bluff, redux

Over 10 years ago (!), I wrote a post about Max vs. Bluff  -- but I no longer remember my reasoning and  the links to the old website don't work anymore so I can't look back at game 604-thousand and something to see what I set my swing die [actually, as I recall, we didn't get detailed game history so maybe I couldn't tell anyway unless I put something in the comments]

I've worked out some possible answers now, but am not as confident as I sounded back then when I was thinking a lot more about Max. Reading another old Max post helps a little

And playing a few new games is refreshing my memory.

Here's a puzzle from a CURRENT game of Max vs. Bluff

It's Bosco312's turn. What's the best capture? there might be more than one reasonably good answer, but there are definitely some significantly less good answers.

Null puzzle

I'm up by 4 sides, but I'm very vulernable to a speed attack. But that only gives irilyth a tie. On the other hand, if he does a non-null attack, he could lose if he rolls a 1,2 or 4. Does he have any better options?
