1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Luckily he did not play any funny lines as I was not prepared for them  4...Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O The first indication of the Marshall although it can still transpose, usually ...d6 is played  8.c3 d5 9.exd5 Terada declined the other two games with 9.d4 but this is no problem after ...exd4  9...Nxd5 10.Nxe5 White could still decline but his acceptance was welcome as he was tactically sponged in his last two Marshalls   10...Nxe5 11.Rxe5 c6 There are a few alternatives but not nearly as satisfactory  12.d4 Bd6 13.Re1 Qh4 14.g3 (14.h3? Bxh3 15.gxh3 Qxh3 and White must play either 16 f4 or 16 Re5 to stave off mate  ) 14...Qh3 15.Qd3 Bg4 This forces the transposition into Spassky's Variation, the critical line  16.Qf1 Qh5 17.Be3 (17.Bd1? Bxd1 18.Rxd1 f5 is clearly better for Black ) 17...Rae8 18.Nd2 Re6 19.Bd1?

A mistake at last! better moves are 19 a4, 19 Bxd5 or 19 Qg2   19...Bxd1 20.Raxd1 f5! This is almost certainly winning already  21.Nb3 Alternatives lose just as quickly, eg (21.c4 bxc4 22.Qxc4 Kh8 23.Nf1 f4 ) ( or 21.Qe2 Qg6 22.Kh1 f4 23.gxf4 Nxf4 24.Qf1 Nd3 25.Qg2 Qh5 26.Nf1 Rxe3 27.Nxe3 Rxf2 28.Rxd3 Rxg2 29.Kxg2 Qg6+ 0-1, Boucchecter-Spassky 1964 ) 21...f4 22.Bxf4?

( I totally missed  14.b4 which looks to be quite a reasonable reply - complete blindness to good moves ) 14...Rb8 15.Be2 O-O ( Perhaps 15...h6 preparing this is better ) 16.Ng5 g6

17.h4 ( Obviously 17.Kf2 is better so as to keep the queen out of b2; there is no hurry to crash open the black king - it won't go away ) 17...Nxd4 18.Bxd4 Qb2 19.Rd1 (19.Kf2 Bxd4+ 20.Qxd4 Ba6 and ) (19.O-O Bxd4+ 20.cxd4 Rb3 are both clearly better for Black ) 19...Rb3 20.h5 Bxd4 21.Qxd4 I agreed a draw because I could not see one of the lines right through. ( Analysis runs  21.Qxd4 Qxc3+ 22.Qxc3 Rxc3 23.hxg6 hxg6 24.Kd2 Rc7 (forced)  25.Rh6 (25.Rh7 allows  25...f6 ) 25...Re8 26.Rdh1 and there are two possibilities  26...Nf8 ( 1)  26...Nf8 27.Rh8+ Kg7 28.Nh7 Kxh8 29.Nf6+ Kg7 30.Nxe8+ Kg8 31.Nxc7 winning ) ( or 2)  26...Kf8 27.Rh8+ Ke7 28.R8h7 Rf8 29.Rg7 Nc5 30.Rhh7 Ke8 31.Bb5+ Bd7 32.Nxf7 (this is the move I missed) and again White probably wins - [Interactive edition editor in 2018 it's a forced draw-   32...Ne4+ 33.Ke3 Rxf7 34.Rxf7 Rc3+ 35.Bd3 Bb5 36.f5 Rxd3+ 37.Kf4 Rd1 38.fxe6 Rf1+ 39.Ke3 Re1+ 40.Kd4 Rd1+ 41.Ke3 etc] ) ) 1/2-1/2
