1.e4 d5 2.exd5 Nf6 3.Bb5+ Bd7 4.Bc4 Bg4 5.f3 Bc8 {The move recommended by Chessbase openings database. and the one I had prepared for this game, it leaves open the option of a6, b5 and Bb7. (RJ)} 6.Nc3 Nbd7 7.Nge2 Nb6 8.Bb5+?! {Not an option given in Chessbase. The usual move is Bb3. Stockfish 9 isn't too keen on it. For me, White is exchanging his strong bishop for Black's problematic bishop. (RJ)} Bd7 9.Bxd7+ Qxd7 10.O-O Nfxd5 11.d3 e6 12.Re1 Be7? {Too timid. Bc5 should be played. I didn't, because of the reply d4. However Black would then have the response Nxc3, messing up White's pawn structure. (RJ)} 13.Nxd5 Nxd5 14.Kh1 O-O-O {Stockfish 8 gives Bh4. (RJ)} 15.Nf4 g5 {I was very happy with this, as Ruari was enticing me to play a move I intended playing anyway. But the engines indicate h5 or Bh4 are much stronger. (RJ)} 16.Nxd5 Qxd5 17.Qe2 Bf6 {Played not so much to put pressure on White's b pawn. It'd always be dangerous for Black to take it. The aim was to to keep the White queen out of e5, thereby avoiding an exchange of queens. The engines say  Bf6 is best. (RJ)} 18.Qe4 Qd6 19.Be3 Qa6 {Best (RJ)} 20.d4 {ALso best (RJ)} h5 {I was confident I had a strong advantage here. But I was wrong. The computers says it's dead even. (RJ)} 21.c3! {Needing to consolidate my centre before moving my queen (R.C)} g4 {Rushing deadlong into the attack. But this is premature. Kb8 is required. (RJ)} 22.Bf4 {Missing the best move, namely Qf4!. it's back to even. (RJ)} Rhg8 23.Re3 {The engines like Rf1 or a4. (RJ)} h4 24.Be5?! {Passing the advantage back to Black. (RJ)} Bxe5 25.Qxe5 Rd5 {Stockfish 9 picks this. (RJ)} 26.Qf6 Rf5 27.Qxh4 gxf3 28.gxf3 Qc6 {BvR.28...Qxe4; 29.fxe4, Rf2 and it seems like a fairly comfortable draw. (??? Qxe4 isn't a move - RJ)} 29.Qe4 Qd6 {Both engines prefer this (RJ)} 30.Rae1? {move 30 queen take H2 and mates your hopeless you couldn,t  beat me in a winning position and you couldn,t beat him patzer lol(JB)} Rh8?? {BvR. Indeed missing an instantaneous win after Qxh2! and R5 mate.Otherwise, a great game from both sides
An oversight by both players. I am very surprised I survived a mate in 2 given I didn't see it, even during postgame analysis (without engine) (R.C) I'm feeling a little sick. (RJ)} 31.R3e2 $15 {In fact Stockfish 9 puts it at -.4 here. (RJ)} Qg3 32.Rg1 Qd6 33.Reg2 Rh3 34.Rf1 Rfh5 35.f4 Qa6 $133 36.Rf3 R3h4 37.a3 Qa4 38.Qc2 Qc6 39.Qe2 Rf5 40.Qf2 Rfh5 41.Kg1 {A very much needed move to avoid the long diagonal and in-between checks after white's pieces have moved (R.C)} Qe8 {Black offered a draw. I was tempted to accept due to the lateness of the game however spotted the now vulnerable back rank (R.C)} 42.Rfg3 Rh8 43.f5 {Trying to break the pawn structure (R.C)} Qa4? {Weakens the back rank (R.C)} 44.Rg8+ $18 Kd7 {Of course not Rxg7 otherwise white is a rook up} (44...Rxg8 45.Rxg8+ Kd7 46.fxe6+ fxe6 47.Qxh4 Qd1+ 48.Kg2 Qc2+ 49.Qf2 Qe4+ 50.Kg3 Qd3+ 51.Qf3 {With no more checks to deliver. If Qb1 there is a mating net. If Qh7, Rg4 and all is well for white (R.C)} Qb1 {[To show a possible line]} 52.Qf7+ Kd6 (52...Kc6 53.Qxe6+ Kb5 54.Rg5+ Ka4 55.Qc4#) 53.Rd8+ Kc6 54.Qxe6+ Kb5 55.a4+ Ka5 (55...Kxa4 56.Qc4+ Ka5 57.Rd5+ Kb6 58.Qb5# {Same result if pawn/ queen blocks (R.C)}) 56.Qd5+ Kxa4 57.Qc4+ Ka5 58.Rd5+ Kb6 59.Qb5#) 45.fxe6+ fxe6 46.R2g7+? {Trying for some kind of king hunt (R.C)} Kc6 47.d5+! Kxd5? 48.Rxh8 Rg4+ {Rxh8 is much better. I believe this move was made under time pressure (~1 minute), with a perpetual check in mind (R.C)} 49.Rxg4 Qd1+ 50.Qf1 Qxg4+ 51.Qg2+ {A very interesting game overall, with a very aggressive attack by black. Very lucky (for me) to not have it cut short at move 32 (R.C)} {#r}
