ALEJANDRO HOFFMAN Well here's the continuation of translation, I hope it's clear as I'm not expert in english (nor too much less!) Continuation: 1.d4 Cf6 2.c4 c5 3.d5 b5 4.cb5 a6 5.ba6 g6 6.Cc3 Aa6 7.Cf3 d6 8.e4 Af1 9.Rf1 Ag7 10.g3 0-0 11.Rg2 Cbd7 12.Te1 (this is the second interesting moment. Rebel follows the fashion. More commonly was played 12.h3 in order to avoid the jump of knight to g4 but was discovered later that it isn't so good. The idea is to make an immediate e5 therefore it's a delicate answer to ponder. I didn't want an equal position and I chose a line not recommended that leaves to the white with advantage but with the characteristic counterplay for the black, typical of the Volga.) 12 Db6 13.h3 Tfb8 14.Te2 Ce8 15.Af4 (if 15. Ag5 the best is 15 ... Rf8) Tb7! (the sign is because the move is an interesting novelty and also it takes out of book to the machine. Before had been played 15 Cc7, 15 Da6, 15 Ta7 y 15 Da5) 16.Dc1 (and the computer makes a mistake in the first play on it's own little-head. It is seen that it hasn't a lot of ideas about the strategic plans of the position. The main move would be 16.Tc1! with idea of Tcc2 y b3. Right from now the black pieces make all the typical moves of the Volga and they pass to have more than compensation for the pawn given.) 16 Cc7 17.Ah6 Ah8 18.a4 Da6 19.Ta2 Tab8 20.Te1 (is obvious that the white pieces don't have a plan) Tb4 21 Dc2 Ce5! 22.Ce5 Ae5 23.f4 (another doubtful move typical of a computer) Ad4 24.Ag5 f6 25. Ah4 Dc4 26.Te2 Tb3! (no 26 Da2 27.Ca2 Tb2 28.Dc4 Te2 29.De2 Tb2 30. Rf2 and the black pieces lost the advantage) 27.Cd1 (unique defense. Rebel will use all its resources but the position is strategically loser) Tg3 28. Ag3 Da2 29.Af2 Af2 (I lost some time with 29 Ca6 y with 29 e5 but they were not good) 30.Tf2 Tb4 31.Cc3 Dc4 32.f5! (seeking counterplay in the king side and eliminating the latente menace of f5) 32 Dd4 33.fg6 hg6 34.De2 Rf7 35.Rh1 Tb8 36.Tg2 Th8 37.Dg4 g5 38. Df3 De5 39.Tg1 Ca6 40.Tg4 c4 41.Rg2 Cc5 42.Df5 Dd4! (Now they are all precise moves that took me a lot of time, not wanting to give the more minimum chance.) 43.Rh2 De3 44.Tg2 Cd3 45.Cd1 Dc1 46. Cc3 Ce5 (not 46 Cf4 for 47.Ce2) 47. Ce2 Db2 48.a5 Da3 49. De6 Rf8 50.Cd4 Dc3! (without falling in the temptation of 50 Da5 that can lost after 51.Dc8 Rg7 52.Ce6 Rh7 53.Cg5 fg5 54.Df5 Cg6 55.Tg5) 51.Dc8 Rg7 52 Cf5 (now it doesn't serve the previous variant for that everything it finishes with the black queen's check in e5) 52 Rh7 53.Db7 Cf3 54.Rg3 Ch4 55. Rh2 De5 (the more simpler)56. Tg3 Cf5 57. Ef5 Rg7 58.Da7 c3 59. De3 Tc8 60.De5 de5 61.Tg1 Ta8 62.Ta1 c2 63.Tc1 Ta5 64 Tc2 Td5 0-1 G.M. ALEJANDRO HOFFMAN
