Tate Variation in the Alekhines should be book move, idk the determination of what is book or not but it’s named on lichess as well as mentioned frequently in other places. Played for a win (50% wr for white) and has a lot of interesting theory backing it(5. Ra3), I have seen it as black and have seen a lot of high rated players use it, very interesting opening
