Mar-05-06  Tariqov: <notsodeepthought>i got the same line as you,seems there are more then one way to win.
Mar-05-06  Uros Jankovic: Love Ivkov's playing style! Always calm and sound, no pretending. The confidence he has, coupled with the unasuming pleasure in the game makes me think of Capa without wanting to compare their absolute values, point being the player "in full" so to speak.Bit tired of the madman's intensity of people like Fisher again without wanting to question their qualities as players.
Mar-05-06  Insightful: <HelaNubo: After 28....Rxd3 29. Rxd3 Qf4+ the white king can move to e2 without losing the piece: 30. Ke2 Qxf1+ 31. Rxf1 and white is up an exchange.> What about 30.Ke2 Qh2+ 31.Qf2 Qxf2+ 32.Kxf2 Rxd3 and black is up a piece.
Mar-05-06  EmperorAtahualpa: Wow, I even got a Sunday puzzle this week!! Well..not completely, my idea was very similar to that of <notsodeepthought>, only I missed the last few moves.
Mar-05-06  aazqua: There are so many ways to win this position it's ridiculous
Mar-05-06  dwojiow: Like <RandomVisitor> I found 28...♕f4+ which I believe wins. White must play 29.♔e2 since 29.♖f3 loses to 29...♕d2 30.♕e2 ♖xd3! .

So the best line seems to be:
28...♕f4+
29.♔e2 ♕h2+
30.♔f3 ♗xe4+!
31.♗xe4 ♕f4+
32.♔g2 ♖d2+
33.♖e2 ♖xe2+
34.♕xe2 ♖d2

And what we end up is an ♖♗ v ♕ ending in which White does not have enough compensation.

Mar-05-06  Parriotblue: <What about 30.Ke2 Qh2+ 31.Qf2 Qxf2+ 32.Kxf2 Rxd3 and black is up a piece.> But if 31.Ke1 Black has nothing more.
Mar-05-06  SickedChess: I see the 28...Bxe4 move in just a second, because I see this puzzle just a year ago! :)
Mar-05-06  dakgootje: Skipped/missed this one as i had only some vague ideas to attack, but no clear one.

  patzer2: Ivkov's decoy 28...Bxe4!!
is one of two possible solutions to today's Sunday puzzle. The other alternative is the deflection (a.k.a. removing the guard) tactic 28...Qf4+!, leading to decisive win of material as explained in <RandomVisitor>'s post.

I chose 18...Bxe4!! as my answer to the puzzle, and visualized the continuation 28...Bxe4!! 29. Bxe4 (29. Rxe4 Rxd3 ). However, at this juncture, I varied from Ivkov's continuation with 29...Rd2+. It wins OK, but it's not as strong as the move actually played by Ivkov.

Mar-05-06  MorphyMatt: One of the easiest puzzles yet.
Mar-05-06  alphee: <notsodeepthought> I had some thing similar to your variation with 28... ♗xe4 29. ♗xe4 ♖d2+ 30. ♔f3 (30. ♔e1 ♕h4+ 31. ♕f2 ♕xf2#) 30... ♕f4#
Obviously e4 had to be the initial target and I did ponder a while if White would take back with the Bishop or the Rook. As I found it stangely simple for a sunday I checked the solution may be too soon.
Mar-05-06  apoorv: Wow! This is probably the easiest Sunday puzzle I have ever seen. I did Qf4+ and so on. There seem to be a lot of ways in which black can win.
Mar-05-06  McCool: 29 ..♖d2+ seems better.
30. ♖e2(only hope) ♕f4+
31. ♔g2 ♕xe4+
32. etc. etc
Mar-05-06  psmith: <McCool>
My solution like that of others was 28... Bxe4 29. Bxe4 Rd2+. But after 30. Re2 Black should just play 30... Rxe2 31. Qxe2 (otherwise mate) Rd2 winning the queen. 30... Qf4+ lets White out with 31. Kg1.
Mar-05-06  RandomVisitor: <dwojiow>in your line Black can improve with the shocking 33...Qxe4+ 34.Kf2 R8d3 35.Ke1 Qd4! 36.Rxd2 Qxa1+ 37.Ke2 Rxd2+ and it is all over. Best for White is either 30.Qf2 or 30.Ke1.

Also, in your 29.Rf3 line, 29...Qh2 is cleaner because white can put up token resistance with 29...Qd2 30.Be2 Bxe4 31.Re3.

Mar-05-06  Trouble: The most important things to be looking for in these tactics is an understanding of the preconditions necessary to initiate the tactic. In this case it would be blacks two strong rooks on the d-file, the potential to attack the king with black queen, the relatively exposed white king on f2 and the fact that black has a greater proponderance of forces attacking the center(whites pieces uncoordinated). Then all you have to do is see how u can use the pieces involved(queen,two rooks, bishop) to best effect.

  Richard Taylor: I found 28...Bxe4 but I dont think that Qf4+ is best

28...Bxe4 29. Bxe4 Rd2+

Now if 30. Kf3 Qf4#

if 30. Ke1 QxR etc

if 30 Re2 RxR+ 31. QxR Rd2 32. Re1 RxQ+ 33. RxR Qf4+ 34. Ke1 Kf7 and Black wins easily

After 29 ...Qf4+ Rf3 but Black also wins after QxB

  Richard Taylor: Lol - I missed after 29...Qf4+ 30. Rf3 Qh2+ and if now 31. Ke1 Qd2#

and 31. Qg2 Rd2+ etc

I'm half asleep lol! - would have solved it if I had been more at my "awake" part of my biorythym or after 10 cups of cofeee!! I knew the B had to slaughter itself on e4 though....

Mar-05-06  SgtSwanson: I think i found an alternative way. Post if you see any errors plz. 28...Rxd3 29. Rxd3 Qf4+

Now there are 5 ways.
30. Rf3 Qh2+ (if Qg2 then Rd2+ win the queen) (if Ke3 then Qd2#) (if Ke1 then Qd2#)

30. Ke2 Qxe4 (wins rook) (up a bishop)
30. Ke1 Qxe4 (wins rook) (up a bishop)
30. Kg2 Qxe4 (wins rook) (up a bishop)
30. Kg1 Qxg1 (trade queens) (then Rxe3) (and be up a bishop). (actually you could just trade queens in the last 3 scenarios and Rxe3 and be up a bishop.

let me know if i missed anything.

Mar-05-06  RandomVisitor: <SgtSwanson>after 28...Rxd3 29.Rxd3 Qf4+, white plays Ke2, now if 30...Qxe4 white plays Kd2 and gets an advantage.

Best play for white after 30.Ke2 is Qh2+ Kf3 Qf4+ Ke2 perpetual check.

Mar-05-06  SgtSwanson: ah didnt see Kd2.

on a differ note.
-anyone have any suggestions for me to improve my end game.. i tend to blow my wins when im up a pawn (can even be passed pawn) and they have a knight and me a bishop. any end-game strats?

ive been viewin most of capablanca games to help. but was wonderin is there any other tips i dont know about.

Mar-05-06  RandomVisitor: Eric Schiller has a book: 639 END GAME POSITIONS: THE ESSENTIAL GUIDE TO CLOSING OUT AND WINNING GAMES.

  kevin86: Here is a case where black goes after a strength rather than a weakness---white's game suddenly collapses under the withering pressure.
Mar-06-06  XMarxT3hSpot: I found Bxe4 but was too lazy to find the next move XD

Btw, was 9. c4 the mistake here? leaving 2 weak squares d3 and e4...
