[Fritz 6 (120s)]

1.d4 Nf6 2.c4 b6 [See the attached analysis from ECO A Rev. 2 of this rare and, as far as I know, unnamed defense. Despite being obscure, it seems to be playable. MB] 3.Nc3 Bb7 4.e3 [ECO mentions 4.f3, 4.d5, and 4.Qc2, but not this modest move. MB] 4...e6 Consolidates d5 5.Nf3 Bb4 6.Bd2 c5 7.a3 Bxc3 8.Bxc3 Ne4 9.Rc1 Nxc3 10.Rxc3 cxd4 [ 10...d6 11.Rd3 Qf6 12.Be2= ] 11.exd4 [ 11.Nxd4 0-0+/= ] 11...0-0 [ 11...Qf6 12.Ne5= ] 12.Be2 White prepares the advance c5 12...d5 13.c5 bxc5 14.dxc5 The passed pawn on c5 will quickly become a dangerous weapon 14...Nc6 15.0-0 d4 [ 15...Qf6 16.Bb5= ] 16.Rc2 [Thought about Rd3 but it seemed to beg for Ba6 or Qd5 and neither seemed appealing. DA] 16...e5 17.Bb5 Re8 18.Re1 f6 Secures g5 [ 18...a6 19.Bd3= ] 19.h3 [Not feeling like there was any particularly good move at the moment, knowing pressure will be in the center and not wanting to risk a back rank mate, seemed appropriate to create space for K or escape for N. DA] [ 19.Nd2 Qc7+/= ] 19...Qa5 20.Bc4+ Kh8 21.Nh4 [Thinking Nf7 has eventual potential or maybe Nf5 and Qg7/\.also thinking Qxc5 = Bf7. DA] [ 21.Nd2 Ne7= ] 21...Ne7 [ 21...Qxc5?? taking the pawn will cause Black grave problems 22.Qh5 g6 23.Qh6+- ] 22.Bd3 [Now thinking that Qh5 could become a nice threat. Thought maybe Bf7 could be better but leaving R on e1 could become an issue with Qxe1. Also, not liking Rc8 response. Also thinking Bd3 slows advance of pawns. DA] 22...Nd5 [ >=22...Rac8!?= should be considered] 23.Be4+/- [Not wanting to allow Nf4 and pinning N to B while contesting the diagonal. I&aposm happy. DA] 23...Rad8 24.Nf5?? not a good decision, because now the opponent is right back in the game [Thinking Nd6 will be perfect. DA] [ >=24.c6 Ba8 25.b4+/- ] 24...Ne3!-/+ A double attack [What???!!! Sigh. What a mess! Am I dead? Let&aposs see. Sigh. fxe3, dxe3, Q where? And down goes B on e4 with pin on R and N. Also, Q is the only thing holding R on e1. Sigh. Nxe3 and I have similar issues with pressure on f2. Sigh. Well, the R might as well take the N and give the Q some room to move. DA] 25.Rxe3 [ 25.Nxe3 Theme: Interference 25...Bxe4 ] 25...dxe3 26.Qg4 Threatening mate: Qxg7 [Maybe I can get a draw....hmmm/\.a mate in 1 threat. Well, saves the B....maybe this is okay after all....maybe I win the B on b7. DA] 26...exf2+ [ 26...g6 27.Nxe3 Rd4 28.c6-/+ ] 27.Kxf2 [I don&apost want to drop the pawn on c5 without a fight. And I don&apost want to pin the R to the K nor do I like Qe1 eventually/\at least Kxf2 will still give me mate threat and limited checks. DA] [ 27.Rxf2 g6 28.Bxb7 Qxc5= ] 27...Rd2+ [ 27...Qc7 28.Bxb7 Qxb7 29.Nd6 Rxd6 30.cxd6 Qb6+ 31.Ke1 Qxd6 32.Rc8-/+ ] 28.Rxd2 [ 28.Ke3!? is worth looking at 28...Rd7 29.c6 Qb6+ 30.Kf3 Qb3+ 31.Rc3 Qxb2 32.Re3= ] 28...Qxd2+=/+ 29.Kg1 The mate threat is Qxg7 29...g6 30.Nd6? Here comes the goal-getter [This does not look great to/for me. DA] [ >=30.Bxb7!? and White can hope to survive 30...gxf5 31.Qxf5 Qd4+ 32.Qf2=/+ ] 30...Bxe4-/+ 31.Qxe4 [If I take the R, then f5 will doom my Q to the g file to protect g2 and he&aposll just munch all my pawns at will. Maybe this way, the c pawn might get a life. DA] 31...Re7 [ >=31...Rb8!? 32.Qh4 g5-+ ( 32...Rxb2?? capturing this pawn is a mistake 33.Qxf6+ Kg8 34.Qf7+ Kh8 35.Qf8# ) ] 32.Qa8+= Kg7 33.Ne8+ [Hmmm. The f pawn might get me somewhere. DA] [ 33.Qd8 Qe3+ 34.Kh2 Qf4+ 35.Kg1 Rf7= ] 33...Kf7 [ >=33...Rxe8!? 34.Qxe8 Qe3+ 35.Kh2 Qxc5 36.Qd7+ Kh6 37.Qd2+ g5-/+ ] 34.Nd6+= [Maybe a perpetual? DA] 34...Ke6?? makes life more difficult [And yes, I miss the mate in two here. (Qg8+, Kd7, Qc8++) DA] [ 34...Kg7 35.Ne8+ Rxe8 36.Qxe8 Qe3+ 37.Kh2 Qxc5 38.Qd7+ Kh6 39.Qd2+ g5 40.Qd8-/+ ] 35.Qc6 [ 35.Qg8+ Kd7 36.Qc8# ] 35...Qd1+ [Thinking big mistake for him leaving the dark squares and the check threats. DA] 36.Kh2 Rd7 [ 36...Qf1 37.Nc8+ Kf7 38.Nxe7 Qf4+ 39.g3 Qd2+ 40.Qg2 Qxg2+ 41.Kxg2 Kxe7 42.b4= ] 37.Qc8 [ >=37.Ne8+ Kf7 38.Nxf6+/- ] 37...Qa4?? a weak move, ruining a winning position [Yep, I missed the mate in two again. (Qg8+, Ke7, Qe8++) DA] [ 37...f5 38.Qe8+ Re7 39.Qc6= ] 38.c6 [ 38.Qg8+ Ke7 39.Qe8# ] 38...Kxd6?? ruins a clearly superior position [ >=38...Qf4+ the rescuing straw 39.Kh1 Qf1+ ( 39...Kxd6?? the knight is taboo 40.cxd7 Qf1+ 41.Kh2 Qf4+ 42.Kg1 Qe3+ 43.Kh1 Qc1+ 44.Qxc1 Kxd7 45.Qh6+- ) 40.Kh2 Qf4+ 41.Kh1 Qc1+ ( 41...Kxd6 capturing the knight is still not a good idea 42.cxd7 Qf1+ 43.Kh2 Qf4+ 44.Kg1 Qe3+ 45.Kh1 Qc1+ 46.Qxc1 Kxd7 47.Qc4+- ) 42.Kh2 Qf4+= ] 39.Qxd7++- Kc5 40.Qe7+ [(K can&apost take c6 because of Qe8+) DA] [ 40.b4+ makes it even easier for White 40...Kc4 41.Qe6+ Kd3+- ] 40...Kb6 [ 40...Kc4 is not much help 41.Qxf6 Kb3 42.c7+- ] 41.Qb7+ Kc5 [And Black offers draw...I decline wanting to play a few more moves and wondering if I&aposll regret not accepting the draw offer. DA] 42.c7 Qf4+ 43.g3 Qd2+ 44.Qg2 Qd4 45.c8Q+ Kb5 [ 45...Kd6 is not the saving move 46.Qgc6+ Ke7 47.Q6e6# ] 46.Qcc6+ [ 46.Qcc6+ Ka5 47.Qgd5+ Qxd5 48.b4# ; 46.Qgc6+ Ka5 47.Q8a6# ] 1-0
