Game of the Week

T.Scott–M.Rohe
RVCCA Ladder Match
Arcadia Books and Café, Spring Green, WI.
June 9th, 2011
Time Control: G/30 +5
[B10: Caro-Kann: 2 d3 and 2 c4]

An interesting game indeed. This match established itself as a ‘Game of Errors’. Played between the current club President and the club’s current ladder leader, it showed the good and the bad -and nothing in between. This was also a game with several stunning moves, lines, and combinations that changed the game completely – on both sides – only to usually be blundered by the same player a few moves afterward. This game is the Game of the Week because it demonstrates the good, the bad, and the ugly – not to mention the unbelievable, good or bad. Note that the computer analysis in [brackets] evaluates the game as the position is at the time. The game advantage was exchanged between players relentlessly. The match result is deserved after each players’ equally honorable and dismaying play during this game. It must be noted that the time control was G/30 +5.

Caro-Kann (B10), anti-anti-Caro-Kann defence

 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3

5…Bd3 6.Qb3 Bxf1 7.Qxb7
[Black king safety dropped {7.Kxf1 Qb6 8.Nf3=} ]

7…Nd7
[Better is: 7…Bxg2!? is worthy of consideration 8.Qxa8 Qb6=/+ ]
Black can win the pawn back with Bxg2.

8.Nxf1
[8.Kxf1 Rc8+/- ]

8…Qc8
[8…Ne5!?+/= is an interesting alternative]

9.Qxc8++/-
[Rxc8 10.Ne3 Ne5 {10…e5 11.b3+/- }]

11.b3
[11.d4 Nd3+ 12.Ke2 Nf4+ 13.Kf3 Ne6+/- ]

11…Nf6
[11…Nd3+ 12.Ke2 Rd8 13.Nf3+/- ]

12.Bb2
[12.Ke2!?+/- ]

12…Nd3++/=
Forks king & bishop, but the knight may have trouble getting back out.
Black inadvertently gives White  a small edge.

13.Ke2
[White threatens to win material: Ke2xd3]

13…Nxb2 14.d4??
[a transit from better to worse [{14.Rb1!?+/= }]

14…Rd8??
[Black threatens to win material: Rd8xd4. Releasing the pressure on the opponent {14…e5!? 15.dxe5 Ne4 16.f3-+} ]
Both players miss some tactics. Black should play e5.

15.Nf3 
[15.Rb1 Nxc4 16.Nxc4 Rxd4= ]

15…e6
[15…Ne4 16.Rhc1 c5-/+ ]

16.a3??
[gives the opponent counterplay {16.Rab1 c5 17.d5+/= (‹17.Rxb2 cxd4 18.Nd1 d3+ 19.Kf1 Bb4-/+ ) }]
White has given Black time to save his knight (or embark on strong attack on the White's king).

16…c5-+ 17.Rhb1
[17.d5 Ne4 (17…exd5?! 18.Rab1-/+ ) 18.Ne5 g6-+ ]

17…cxd4 18.Nf1 d3+ 19.Kd2 Ne4+ 20.Ke3
[20.Kc1-+ ]

20…f5
[20…d2 might be the shorter path 21.Rxb2 d1Q 22.Rxd1 Rxd1 23.Kxe4 Rxf1 24.b4-+ ]

21.Rxb2 Bc5+ 22.Kf4 g5+!
[the final blow] (or is it?)
White's king faces a potentially lethal attack.

23.Nxg5 e5+! (?)
[Deflection: g5]
Bd6+ wins the knight.

24.Kxf5
[24.Kxe5 Nxg5 Deflection (24...Bxf2 Zwischenzug) ]

24...Nxg5 25.Kxg5 Rg8+ 26.Kh6
[26.Kh4 Bd4 27.Rab1 Bxb2 28.Rxb2 Rxg2 29.Rd2-+ ]

26...Bd4
[26...Bf8+ 27.Kxh7 Kf7 28.g3 Rd6 29.f4 Rh6# ]
With White's move, Black can potentially checkmate in a few moves (starting with Bf8+), but Black doesn't take advantage & instead goes for the skewer on the two rooks.

27.Rab1 Bxb2 28.Rxb2 Rd6+
[28...Rxg2!? seems even better 29.Kh5 Rd4 30.Rd2-+ ]

29.Kh5 e4
[Better is: 29...Rxg2 and Black can already relax 30.Rd2 e4-+ ]

30.b4??
[White crumbles in face of a dire situation {30.g3 Rf8 31.Rd2 Ra6-+ }]
White is better off securing his king's position

30...Rf6
[30...Rxg2 keeps an even firmer grip 31.c5 Rf6 32.Rb1 Rgxf2 33.Ne3-+ ]

31.Rd2??
[terrible, but the game is lost in any case {Better is: 31.Ne3-+ }]

31...Rf5+ 32.Kh4 Rf4+
[Better is: 32...Rxg2 secures victory 33.Rd1 Rf4+ 34.Kh3 Rgxf2-+ ]
Black misses his last opportunity to grab the g-pawn & allows the White king to get back to safety.

33.Kh3 Rf6
[33...Rgf8!? 34.Kg3-+ ]

34.g3-/+ Rf3 35.Kg2 Rgf8
[35...Kd7 36.Ne3 Rgf8 37.h3-/+ ]

It should be noted that at this time White's clock stands at 10 minutes and Black's at 5 minutes.

36.c5
White gets more space [36.h3!?=/+ has some apparent merit]

36...Kd7-/+ 37.b5
[37.Ne3 Kc6-/+ ]

37...Kc7
[37...R3f5 38.c6+ Kc7 39.a4-+ ]

38.a4?
[Better is: 38.Ne3!? Rd8 39.g4-/+ ]

38...R8f5 39.b6+?
[39.c6-+ ]

39...axb6 40.cxb6+ Kxb6 41.Ne3 Rc5 42.Rxd3 exd3 43.Kxf3 Ka5
[43...Rc1 seems even better 44.g4 Re1 45.Nc4+ Kc5 46.Nd2-+ ]
Black's move allows White to have some counterplay; better is 43...Rc1, then get behind the passed d-pawn, and Black would have a winning position.

It should be noticed that at this time White's clock stands at 4 minutes and Black's at 2 minutes.

44.h4?
[44.Ke4 d2 45.Kd3 Rd5+ 46.Kc2 Rd4-+ ]

44...Kxa4
[Better is: 44...Rc1 might be the shorter path 45.Ke4 d2-+ ]

45.g4??
[an oversight. But White was lost anyway. {Better is: 45.Ke4 d2 46.Kd3 Rd5+ 47.Kc2-+ }]

45...Rc3
[Better is: 45...Re5 and Black takes home the point 46.Nc4 Re2 47.Ne3-+ ]

46.Nd5 Rb3
[Better is: 46...Rc6 makes it even easier for Black 47.Ke3 d2 48.Kxd2 Rd6-+ ]

47.h5
[47.Ke3 Kb5 48.Kd2-+ ]

47...Rb5?
[Better is: 47...d2+ secures the point 48.Ke2 d1Q+ 49.Kxd1 Rd3+ 50.Ke1 Rxd5-+ ]
Black makes a careless move which allows his rook & king to be forked, thus giving White the better winning chances.

48.Nc3!+ +- Ka5 49.Nxb5 Kxb5 50.Ke3 Kc4 51.Kd2 Kd4 52.f3
[52.g5 Kd5 53.f3 Ke6 54.Kxd3 Ke5 55.f4+ Ke6 56.Ke4 Kf7 57.f5 Kf8 58.h6 Kg8 59.Kd4 Kf7 60.Ke5 Ke7 61.g6 hxg6 62.h7 Kd7 63.Kd5 Kc7 64.h8Q Kb7 65.Kc5 gxf5 66.Qh7+ Ka6 67.Qc7 f4 68.Qb6# ]

52...h6 53.g5!
[the end, the rest is history] (or it should have been)
With proper technique, White will promote a pawn & should win this position.

53...hxg5
[53...hxg5 54.h6 Passed pawn; With the idea: 53...-- 54.gxh6 Wins material]

54.h6 Ke5

62...Kg1
[62...Kh3 does not win a prize 63.Ke3 Kg3 64.Qg6 Kg2 65.Qxg4+ Kf1 66.Qg8 Ke1 67.Qg1# ]

63.Qe3+
[Twofold repetition {63.Qxg4+ Kh2 64.Ke2 Kh1 65.Kf3 Kh2 66.Qg2# }]

63...Kh1??
[instead of simply winning the game {63...Kg2 64.Ke2 g3 65.Qd2 Kh3 66.Kf3 Kh4 67.Qh6# }]

64.Qe2 g3
