Jun-16-22		PawnSac: After 11. ...0-0 click for larger view Opening Explorer In this position Yu played... < 12.Qb3 > with a slight plus for white. Stockfish quickly passed all the known moves in the cg database above in the first second [ 00.00 - 00.01 ], and stayed with 12.Qb3 for 4 hours up to 53/70. Then after 15 hours it flipped back to Qc2 for two more ply [see below]. I suspect it will toggle back and forth with Qb3 & Qc2 for a bit, but Qb3 is a solid alternative. In the past when a top level player introduced a new move, we'd call it a "novelty". In this case it's clearly an engine move, and not really something Yu cooked up on his own at home. Nevertheless, he prepared well to answer black diversions from the engine line, and 12.Qb3 may become the latest fashion in this opening. We'll have to wait and see who takes interest in it. 53/70 4:01:15 11,180,806k 772k +0.42 12.Qb3 Rfc8 13.h3 b5 14.Rfc1 h6 15.a3 Bc6 16.Rc2 Nb6 17.Qa2 Be8 18.b3 Rcb8 19.Rcc1 Rc8 20.Qb2 Rab8 21.Qd2 Rc7 22.Qa2 Nc8 23.Ne5 Ne7 24.Ne2 Rbc8 25.Rxc7 Rxc7 26.f3 Nd7 27.Nxd7 Bxd7 28.Qd2 Nc6 29.b4 Ne7 30.Rc1 Nc8 31.Rc5 Nb6 32.Qc2 Rc8 33.Rxc8+ Nxc8 34.Qc5 Qc6 35.Qxc6 Bxc6 54/71 14:57:12 18,713,844k 348k +0.37 12.Qc2 Rfc8 13.Rfc1 Qe7 14.h3 Rc7 15.Qa4 h6 16.Ne2 Rcc8 17.Rxc8+ Rxc8 18.Rc1 Rxc1+ 19.Nxc1 Nb8 20.Ne5 Qc7 21.Ne2 a5 22.Bb5 Ba6 23.Bxa6 Nxa6 24.Nc3 Nb8 25.Qa3 Ne8 26.h4 Nf6 27.g3 Qd8 28.f3 Qc7 29.Kg2 Ne8 30.Qa4 Nf6 31.g4 Nfd7 32.Nd3 Nc6 33.Nb5 Qd8 34.Qc2 Ndb8 35.h5 Qd7 36.a4 Na6 37.Qc3 Nab4 55/69 16:25:31 22,742,714k 385k +0.40 12.Qc2 Rfc8 13.Rfc1 Qe7 14.h3 Qd8 15.Qd1 h6 16.Qb3 Ne8 17.Qa3 Nef6 18.Rc2 Rc7 19.Rac1 Rac8 20.Qb3 Rc6 21.Nd2 Ne8 22.Qb4 R6c7 23.Bf1 Rc6 24.Qa4 b5 25.Qb3 Nb6 26.a4 Nc4 27.axb5 axb5 28.Nf3 Ned6 29.Qb4 Qa5 30.Qxa5 Nxa5 31.Ra1 Ra6 32.Ne1 Nb3 33.Rxa6 Bxa6 34.Na2 Rxc2 35.Nxc2 Na5 36.Nab4 Bb7 37.Ne1 Kf8 38.Ned3
