Ne5 Nxe5 8. dxe5 = (1.53) Depth: 11 00:00:42.13 11645kN After Kh3? Zappa goes extension crazy and ends up giving a big plus to Black: 1...Ne4 2. Bxe4 Nf4 3. exf4 fxe4 4. f5 e5 5. Qxe4 dxe4 6. fxg3 hxg3 7. Kxg3 = (3.10) Depth: 9 00:01:31.52 20541kN Another pivotal move seems to be 23. Nc1. Zappa plays it for a while, then gives it up for f4. 1. f4 Ng4 2. Qd2 Nh2 3. Rh1 Ng4 4. Rf1 = (0.00) Depth: 10 00:00:52.17 13919kN After 23. Nc1, Zappa announces mate. 1...Nh7 2. f4 Qg5 3. Qd1 e5 4. Be2 exf4 5. Rxf4 Qg4 6. Rxg4 fxg4 7. Bxg4 Ng5 = MAT6 Depth: 9 00:00:02.65 761kN anthony
