8-ball tactics

Dear pool players who are better than me,

You are playing a game of 8-ball, are trying to run out the solids, and things have gone a little awry (table 1) or significantly awry (table 2). You are down to one solid ball remaining in each case. Discuss what you think the best course of action would be.

On each table, the stripy balls not indicated can be assumed to be in reasonably generic places, without any clusters. On the first table, the 8-ball does not go into any of the lower corner pockets.
