read moreAndrew usually runs his middle stair stack horizontally, but chose to display it vertically today — you can always "flip" a grid along the NW to SE diagonal with no changes in entries. (There are technical reasons for this, but they're incredibly boring, so just trust me. An example of two grids that are equivalent except for flipping: the first pair in the Misenko duplicates.) So, why place MARTIN SHEEN / LECTURE TOUR / LETTUCE WRAP vertically instead of horizontally?
One reason is that it lets Andrew feature all the goodies running across that stair stack: ANSWER ME THIS, SPORT UTILITY, SWIM UPSTREAM, MAKEUP ARTIST, NO BOTHER. He usually gets a lot of long answers running through his stair sticks, but today's felt even stronger.
Another is that if you flipped the grid as described above, your 1-Across would be APPAL. Not an appalling answer, but not a good one, either. 1-Across is the first answer most solvers will look at; it's so important to start things off on the right foot.
It seems ridiculous that something as easy as grid-flipping would make a difference, but having a poor 1-Across entry can be such a turn-off. These little tricks can be important.
One con to today's presentation is that it places VIREO across the middle, glaring and sticking out more than if it were vertically oriented. This one tough entry is fair, but when you combine it with PAREVE, the RIVER PO, MISSAL, and PLAIT (usually called a "braid" in the US), it makes for a lot of entries that could be called "weird." That's an unfair assessment, but if you make a solver feel dumb, that affects their perception of a puzzle's quality.
Overall, it's not my favorite of Andrew's (stellar) body of stair-stack work, especially considering he also needed a bit of RDA TET ITA TBA to make it work. Certainly enough juice from the long entries to make it still enjoyable, though.
