If rollout differs from analysis, it's usually an indication that you need a longer or better rollout.  For instance, I usually analyze at 2-ply and roll out at 0-ply.  If they agree, then I accept it, but if they don't  I go for a 2-ply rollout.

In this position, I'm pretty sure the hit is correct, but I'm not sure where to play the ace: 24/23 doesn't do anything constructive, 9/7 makes a candlestick, and slotting may be too counterindicated due to his stronger position.  I'd slot the 7 point (fewer return hits than slotting the 5) and hope to make a point next turn. The thing is, we're just about guaranteed to be on the bar next turn with a loose hit - how best to prep for a hitting festival?  maybe covering up is best?
