A lovely puzzle today. The heart-shaped grid and a nice sprinkling of love- and heart-themed clues (9A Loving, maybe (GERUND), 42 Game of "love" (TENNIS), 14D Attracted (DREW)) are set off by three long theme answers: HEARTSTRINGS, CUPIDSARROWS, and smack dab in the middle, the hero of the day: SAINTVALENTINE.
My FWOE came when I entered DINGy at 58A (Dark, dirty shade) instead of DINGE, a form of the word I'm not sure I've encountered before. Of course, CATTLy (50D. Range rovers) isn't a word, but I didn't notice that problem until after I completed the grid. Derp.
I liked 15D. Bad place for a bowling ball or the mind (GUTTER) and 35D Game's turning point (ROTISSERIE) - ha! We also get another nice PINATA clue (38D. One getting smashed at a party?). Parsing GOONASPREE and SOANDSOS in the grid after the solve is fun.
I haven't heard the term MCJOBS before (Unfulfilling work assignments), but it seems apt. Apt! I have very little knowledge of and, apparently, no memory at all for sport stadiums, especially those named for corporations, so Citi Field team, on scoreboards (NYM) was not a gimme for me, but I eventually came up with it after yCJOBS and gCJOBS weren't getting the job done. And speaking of new-to-me items, I've never heard of POPOV. Huygens?
We have another example the recently discussed clue type at 10D Beat it! (DRUM). Is there a name for this type of clue?
I thought starting off a love-filled puzzle with HAGS was a little unfortunate, and TWPS lacks ARTISTRY, no matter how you slice it, but who's complaining on love's big day? NOTI.
