Hi! Can someone please explain to me what goes on in Fritz blundercheck. This is a game I played at ICC the other day. Timelimit 3 0. Blundercheck settings 10 s/move, threshold 0.15. Side to analyze white [Fritz 6a] 1.c4 g6 2.Nc3 Bg7 3.Nf3 c5 4.e3 Nf6 5.d4 0-0 6.dxc5 Na6 7.Bd3 last book move 7...Nxc5 8.Bc2 d6 9.h3= [0.00 Fritz 6: 9.0-0 Na6 10.e4 Qc7 11.Nd5 Nxd5 12.cxd5 Bg4 13.Re1= 0.13/9 ] 9...Be6 10.Qe2 Rc8 11.Rb1± [0.72 Fritz 6: 11.e4 Ncd7 12.Bd3 Nc5 13.Bc2= 0.00/9 ] 11...Qa5 12.b4 Qa6 13.bxc5 Bxc4 14.Qd1 Rxc5 15.Na4² [0.28 Fritz 6: 15.a4 Rfc8 16.Ba3 R5c7 17.Qd2 b6 18.e4 Qa5² 0.69/9 ] 15...Rc7 16.Bb2 Bxa2 17.Ra1 Bc4 18.Nd4= [0.22 Fritz 6: 18.e4= 0.09/8 ] 18...Nd5 19.Qd2² [0.34 Fritz 6: 19.Be4= 0.22/8 ] 19...b5 20.Nc3 Qb6 21.Nxd5 Bxd5 22.0-0 e5 23.Ne2 Bc4 24.Rfd1= [0.22 Fritz 6: 24.Be4 d5 25.Bxd5 Rd8 26.e4 Rcd7 27.Rfd1 Bxd5 28.exd5 Rxd5² 0.34/9 ] 24...d5 25.Ng3 b4 26.Bb3= [-0.06 Fritz 6: 26.Ba4= 0.16/9 ] WHAT'S THIS??? Due to a mouseslip I play Bb3, was planning Ba4. I just drop a piece to Bxb3! but Fritz assesses the position as almost even!! 26...a5 27.Ba4 Rd8 28.Rac1 Rc5 29.Ne4 Rcc8 30.Ng5 h6 31.Nf3 d4 32.exd4 e4 33.Nh2 Kh7 34.Qe3 f5 35.g3 Bd5 36.Nf1 Rxc1 37.Rxc1 Rd7 38.Bxd7 Qd6 39.Ba4 g5 40.Rc5 f4 41.gxf4 gxf4 42.Qe2 f3 43.Qe3 Qg6+ 44.Ng3 Be6 45.Qf4 Bxh3 46.Qxe4?+- [17.19 Fritz 6: 46.Rc7+- 8.66/8 ] 46...Bf5 47.Qxf5?+- [11.59 Fritz 6: 47.Rxf5 Bf6 48.Be8 Qxe8 49.Qxe8 Bg7 50.Rxf3 b3 51.Rxb3 Bf6+- 17.19/10 ] 47...Qxf5 48.Nxf5 h5 49.Nxg7?
