Feb-03-12  BOSTER: <FSR> <Na4- what was white thinking ?>.

It's not easy to read the thoughts of players.
But many believe that style in chess as a mirror reflects player's personality.

White position is difficult.
Black has a center, the opened h file, active pieces.

Playing knight on a4,( everybody knows that knight on the edge is not good) white continues the chasing black queen, attacking pawn c5 and protecting his pawn on b2. But white has clearly understand that after this move the mobility of the white queen is very limited.

Playing very sharp b4 white could create the play on the queen's side, because black need at least couple moves to use the weakness on h2.

This is the pos. 22.with b4 (instead Kh1)

Maybe white wanted to play 22.Nxc5, ,but then didn't decide this.

Feb-03-12  TheBish: W Doubleday vs Kudrin, 2004

Black to play (25...?) "Difficult"

25...Rxh2+! 26. Kxh2 Rh8+ 27. Kg3 Qe7 28. fxe5 Qg5+ 29. Kf3 Qf5+ 30. Kg3 (30. Ke2 Qe4+ 31. Kd2 Qe3#) Bxe5+ 31. Rf4 Qxf4#.

Of course, White can throw away a piece or two more, but mate is the end result.

Feb-11-12  morfishine: <James D Flynn> Thanks for the comments! I really appreciate it. You pointed out one of the reasons for 26...g5: It opens up <g6> for the knight

  perfidious: <....and now White gets to experience the full girth of Black's chess phallus....>

Dang if that ain't impressive.

Aug-14-22  2071 S Milwaukee: Not really. Wassup here...

<Feb-03-12 squaresquat: you people are thieves and cheats. it's a sad thing to be so lacking in virtue. You charged me. I go to Java and punch buttons. you people fence me out because of my verbal mastery and your rhetorical ineptitude.>

Nov-04-22  jrredfield: I saw 25 Rxh2. Comments from previous years sum it up.
Nov-04-22  Brenin: 25 ... Rxh2+ 26 Kxh2 Rh8+ 27 Kg3 Qe7, followed by 28 ... Qh4+ or 28 fxe5 Qg5+, looks good enough for a Black win.
Nov-04-22  stacase: And after 26.Kxh2?
26...Nf3+ looked good as it removes protection of White's f4 Pawn. IF White takes the poison Knight. However White can just move his King and the attack falls apart. So I got the first move.
Nov-04-22  Brenin: 12 Nxb5 was a mistake, but after 12 ... Qxd5 13 Bxf6 Black should play 13 ... exf6 rather than 13 ... Bxf6, so that 14 Nc3 is answered with 14 ... Re8+, e.g. 15 Be2 Qxg2, or 15 Ne2 Nc6, with significant advantage to Black. Of course, 14 Nxc7 loses to 14 ... Qa5+.

  thegoodanarchist: Take me out to the chess game
Take me out to the crowd
Buy me some peanuts and Cracker Jack
I don't care if I never play black
For it's root root root for my pieces
If they're not active its bad
And it's check! check! mate and you're lost
At the old chess game!

  al wazir: I played 29...Qe3+, which also wins: e.g., 30. Kg4 g5 31. Rxf7+ Kxf7 32. Qb7+ Kg6 33. Qf3 Rh4+ 34. Kg3 Bxe5#.

I see I found the same move ten years ago, the last time this was the game of the day.

Nov-04-22  jrredfield: oops I meant 25 ... Rxh2+
Nov-04-22  mel gibson: That wasn't difficult.

Stockfish 15 says mate in 8:

  agb2002: Black can start a mating attack against the white king with 25... Rxh2+ 26.Kxh2 Rh8+:

A) 27.Kg3 Qd8 28.fxe5 (due to Qh4#) 28... Qg5+

A.1) 29.Bg4 Qe3+ 30.Bf3 (30.Rf3 Bxe5#) 30... Bxe5+ 31.Kg4 Qf4#.

A.2) 29.Kf3 Qf5+ 30.Ke2 (30.Kg3 Bxe5+ 31.Rf4 Qxf4#) 30... Qe4+ 31.Kd2 Qe3#.

B) 27.Bh5 Rxh5+ 28.Kg3 Qd8 29.fxe5 Qg5+ 30.Kf3 Qf5+ 31.Ke2 (31.Kg3 Bxe5+ 32.Rf4 Qxf4#) 31... Qxc2+ 32.Kf3 (32.Ke1 Rxe5+ 33.Qe2 Q(R)xe2#) 32... Rf5+

B.1) 33.Kg4 Qe4+ 34.Kh3 (34.Kg3 Rg5+) 34... Rh5+ 35.Kg1 Rg5+ 36.Kh3 (36.Kh2 Qxg2#) 36... Qxg2+ 37.Kh4 Qg3(4)#.

B.2) 33.Kg3 Rg5+ 34.Kh4 (34.Kf3 Qxg2+ 35.Kf4 Qg4#; 34.Kf4 Qf5#; 34.Kh2 Qxg2#; 34.Kh3 Qxg2+ 35.Kh4 Qg3(4)#) 34... Qe4+ 35.Kxg5 (35.Kh3 Qg4+ 36.Kh2 Qxg2#) 35... Be3+ 36.Rf4 Qxf4#.

Nov-04-22  AlicesKnight: Saw the break-in with ... Rxh2+ and ... Rh8+ with ... Qe7. The exact follow-up needs more care than I gave it.
Nov-04-22  Nosnibor: This is more like a Monday puzzle. Very obvious mating pattern.
Premium Chessgames Member
  scormus: Nice to see a POTD without a proliferation of alternative feasible moves.
Nov-04-22  Gowe: The ending was quite simple, at least considering I spent a lot more time on thursday and wednesday puzzles. I was able to see it to the end. The rook sacs was pretty clear to me, and then it was a matter of how to chase the king.

27... Qe7 was easy to spot, because it lead to mate in one. So I analyzed moves for white and only possible way to continue the game was taking the knight.

Then I considered Qh4+ and Qg5+ and realized that Qg5+ was better because you need to give a check on f5 later with the resulting of mate in 2 if 30.Kg3 (Bxe5+) or mate in 2 if 30.Ke2.

Nice puzzle!

Nov-04-22  TheaN: Ah nuts! I didn't finish this properly. After <25....Rxh2+ 26.Kxh2 Rh8+ 27.Kg3> interposing the bishop here just makes a potential mishap from Black manageable. <27....Qe7 28.fxe5> so far so good. This is all pretty much forced, given without fxe5 Black's threatening Qh4#.

Here however, I really wanted 28....Qh4+?! to work. I looked at 28....Qg5+!, thought 29.Bg4 would reload a defensive piece and discarded it. The key line then is 29....Qe3+ and the dark square weaknesses. Ie, 30.Rf3 Bxe5# but also 30.Bf3 Bxe5! #1. White really misplaced his pieces too much to come back to the king's defense.

After <28....Qh4+?! 29.Kf3>, the best move seems to be 29....Qg5! with 30.g3 Rh3 -+ and a significant plus for Black. Instead, my <29....Qh5+? 30.Ke4 Qxe5+ 31.Kd3 Rd8! => looks very dangerous, but it's only a draw after 32.Re2! with best play. Twice in a row I let a win slip away.

  chrisowen: I tock mad question Rxh2 abled it's leeway doh it's axiom jag afford position game Rxh2 ebb;
Nov-04-22  Mayankk: Black has a rock star Bishop stationed at d4, blocking key escape squares (g1, f2 etc) for the White King. Black can exploit this by the Rook sac 25 ... Rxh2+ 26 Kxh2. After this there are 2 candidate moves, 26... Ng4+ or 26 ... Rh8+.

The key now is to choose a sequence which permits the c7 Queen to join the attack forcefully. 26 ... Ng4+ struggles in this respect as after 27 Kg3, there is no easy way for a forced entry for Black Queen. 26 ... Rh8+ 27 Kg3 Qe7 seems more forceful as it threatens mate via 28... Qh4#. After 28 fxe5, 28... Qg5+ let's the Queen enter the playground with a check. And it's unlikely White King can survive the attack.k

Nov-04-22  vajeer: I found this easy actually. It's screaming for rook sacrifice, and king hunt is not difficult to spot. In fact black can mate in 3-4 different ways. In that sense it is easy, it's not easy for black to make a mistake and turn win into defeat!
Nov-04-22  Refused: hum, this one was easier than expected.
With the Bishop sitting on d4 and white missing a pawn on f2, 25...Rxh2+ just screams to be played. It forces the following sequence of moves. 26.Kxh2 Rh8+ 27.Kg3 Qe7 28.fxe5 Qg5+ 29.Kf3 Qf5+ 30.Ke2 Qe4 31.Kd2 Qe3#

The first real alternative for white was 30.Kg3 Bxe5+ 31.Rf4 Qxf4#
