  Oxspawn: Sharper than usual for a Tuesday but I am not complaining, since I earned my coffee!
Jan-06-15  KingsPawns: Good morning to all!
First login in years. Feels refreshing to be back!
Nice trade of rook and queen, but I would much rather play: 44...Qe4 45.Kb3 Rd3 46.Qf2 Qb4 47.Kc2 Qc3#

  Penguincw: Both sides have rooks hanging, but black can pull a desperado with 44...Rxc3+, and then eventually getting the queen.

  OhioChessFan: <KP> welcome back after 5 years. Your line is fine, but it's not to mate. <46. Ra8+> lets White fight on a while.

Maybe 46. Ra8+ Kc7 47. Ra7+ Kb8 48. Kc2+ Kxa7 49. Qxd3 Rc1+ 50. Kxc1 Qxd3 which is esssentially the same thing as the game line.

Jan-06-15  varishnakov: 44...RxP+ 45.QxR R-B8+ 46.KxR QxQ+ 47.R-B2 QxR and

black has a queen for a rook

Jan-06-15  CHESSTTCAMPS: <KingsPawns> Clever idea - wish I'd noticed it. After 44...Qe4+ 45.Kb3 Rd3!, I particularly like 46.Qc2 Qb4#. Best play seems to be 46.Ra8+ <OCF> Kb7 47.Kc2+ Kxa8 48.Qxd3 Rc1+, taking a more direct path than OCF's line.
Jan-06-15  varishnakov: I want to think the horse is the beef and the bishop eats him on move 4.
Jan-06-15  TheaN: Tuesday 6 January 2015 <44....?>

In this unbalanced position, Black's major pieces surround the white king. Meanwhile the knight is out of play, the queen is en prise and the white rooks are close to invading the Black position as well.

Again this is an example of the king being a bad defender. White decided (or was forced) to defend the crucial squares around his king with the queen, rook and king, against the invading three major pieces of black. Especially for the queen the king is a bad defender, as losing control can easily mean heavy material losses.

In this position, Black can use the lack of defense, a king deflection and the loose rook on a5 to gain decisive material: <44....Rxc3+ 45.Qxc3 Rc1+!> the point that duo defending a square with queen and king is bad. If 46.Kd2/d3 Qxc3+ 47.Ke2 Re1+ 48.Kf2 Qe3# quickly decides, but after <46.Kxc1 Qxc3+ 47.Kb1 Qxa5 > white is down a queen for rook in a hopeless position.

Jan-06-15  TheaN: Interesting that after 44....Qe4+?! 45.Kb3 Rd3! essentially leads to the mainline. It's slightly slower thus objectively Rxc3 evaluates -10, Qe4+ -8.

The interesting aspect of 44....Qe4+ is that it gives white the opportunity to be mated or resign, or find a rather complex defense that still goes down a queen for rook. In a sense, Qe4+ is the psychological knockout, Rxc3+ is just brute force action. Many chess players prefer the latter, for its simplicity.

Jan-06-15  KingsPawns: <OhioChessFan> Your defense line made me open up my chessboard to calculate after God knows how long. Thank you for that. What I like the most about your line is that in some point black can think there's a escape route in 44...Qe4 45.Kb3 Rd3 46.Ra8+ Kc7 47. Ra7+ Nb7 48. Rxb7+ Kd8 49. Ra8 Ke7... trying to hide behind the pawns in a black square on the other side of the board and away from the bishop's threat. But then 50. Re8! just kills black's dreams. Great defense line indeed!

  patzer2: <varishnakov: I want to think the horse is the beef and the bishop eats him on move 4.> Yes indeed he does! Don't know where the term "Beefeater" came from for the A40 Dzindzi Indian <1. d4 g6 2. c4 Bg7 3. Nc3 c5 4. d5 Bxc3+ 5. bxc3 f5> played in this game.

However, it's an infrequently played opening which scores quite well for Black.

Out of 409 games in the <cg> opening explorer in the Modern Opening line < 1. d4 g6 2. c4 Bg7 3. Nc3 c5> (think of 3...c5 being the invitation to play 4. d5 and allow Black to "eat the horse" with the fianchetto Bishop)," Black scores 44.7% wins while White scores only 28.4% wins and 26.9% draws.

Out of 117 games in the <cg> opening explorer in the A40 Beefeater variation <1. d4 g6 2. c4 Bg7 3. Nc3 c5 4. d5 Bxc3+ 5. bxc3 f5>, Black scores 53.8% wins while White scores 28.2% wins and 17.9% draws.

  patzer2: Correction: White's (not Black's) game seems to take a turn for the worse after 25. Nb1?! Instead, 25. f4 Nf7 26. Rbb1 = keeps it about level.
Jan-06-15  YetAnotherAmateur: Forcing move: 44. ... Rxc3+ 45. Qxc3

That allows 45. Rc1+, which either diverts the king away from protecting c3 (Kxc1) or leaves to attackers on the queen to one defender (Kd2 or Kd3). Not grabbing the rook doesn't seem to help, so:

45. ... Kxc1
46. Qxc3+ Kb/d1
47. Qxa5

I think white would have been better off with 41. Rxa5 rather than 41. Bh5, but he's losing before that point.

Jan-06-15  CHESSTTCAMPS: <KingsPawns> You're giving too much respect to the 46.Ra8+ defense (after 44...Qe4 45.Kb3 Rd3). 46... Kb7 wins easily, after either 47.Rxd8 Qb4+ 48.Kc2 Rxd2+ 49.Kxd2 Qxb2+ or 47.Kc2+ Kxa8 or 47.Rb8+ Kxb8 48.Kc2+ Ka8.

  kevin86: The rook sac leads to gaining the queen for two rooks...then picking up the stray rook at a5.
Jan-06-15  KingsPawns: <CHESSTTCAMPS> 44... Qe4 is still a good move for black, but there's no forced checkmate. <ocf> explained it very well. Ra8+ prevents the early end of the match by forcing the black king to move to the "b" column, so that white can make a discover check with Kc2+, trading a loss for a desfavorable change of material.
Jan-06-15  GoldenKnight: Got this one all the way, but I wouldn't call it "easy."

  Bubo bubo: Black wins the queen for a rook with 44...Rxc3+! 45.Qxc3 Rc1+ 46.Kxc1 Qxc3+ and 47...Qxa5. A nice bunch of tactics: skewer/removal of the guard and a fork!
Jan-06-15  stst: easy but not really so...
quite many lines, one viable:

44 ...... Rxc3+
45 Qxc3 Rc1+
46 Kc1 Qxc3+
47 Kb1 Qxa5

Black winning

Jan-06-15  Whitehat1963: Missed it.
Jan-06-15  M.Hassan: "Easy"
Black to play 44...?
Black is a pawn up

44..........Rxc3+
45.Qxc4(forced) Rc1+
46.Kxc1 Qxc3+
47.kb1 Qxa5

Black fives 2 Rooks and gets a pawn+Queen+Rook
Not bad

Jan-06-15  BOSTER: <TheaN: Meanwhile the black knight is out of play>.

If you look at the pos. after 38.Rb6, you'd understand that black knight was the main defender of black King.

  patzer2: I was going through this game with one of my grandsons to show him the daily puzzle combination, when we noticed the combination actually begins one move earlier than the puzzle position (44...?).

Black's five move combination actually begins with the pin and deflection move 43...Qb4+! which forces 44. Kc2 and sets up the winning follow-up 44...Rxc3+ 45. Qxc3 Rc1+ 0-1.

White resigns in lieu of 46. Kxc1 Qxc3+ 47. Rc2 Qxa5 with a huge material advantage.

  patzer2: After a second look, it's at least a seven-move combination beginning with 41...Qe4+! .
