I am just playing a chess game on the chess server chess.com, where each player has a thinking time of three days per move - one could say it's the opposite of lightning chess ... :)
Playing this kind of long-term chess one should be aware to be dependent on the fairness of the opponent, because nobody can be completely sure that the other player isn't utilizing any chess software in critical situations.
In this match that hasn't been the case for sure though: the game went really crazy, because my opponent - hats off - did everything possible to attack with the black pieces. Here you can see the current progression of the game (which hasn't finished yet):
1. f4 e5 2. fxe5 d6 3. exd6 Bxd6 4. Nf3 Nf6 5. d4 Nc6 6. e4 Bg4 7. d5 Bxf3 8. gxf3 Nxe4 9. fxe4 Qh4+ 10. Kd2 Bf4+ 11. Kd3 Nb4+ 12. Kc3 Bxc1 13. Qxc1 Qxe4 14. Bc4 O-O 15. Kxb4 b5 16. Na3 c5+ 17. Kxb5 Rfb8+ 18. Ka5 Qe7 19. c3 Qc7+ 20. Ka4 Qd7+ 21. Bb5 Rxb5 22. Nxb5 a6 23. b4 axb5+ 24. Kb3 Qxd5+ 25. Kb2 cxb4 26. Rd1 Qc5 27. Qd2 h6 28. cxb4 Qe5+ 29. Kb3 Qc7 30. a3 Qc4+ 31. Kb2 *
The fog has lifted, and if no miracle happens (for example a blackout from my side) I will win this game.
However black could have played better. If instead of 16. ... c5+ he had moved 16. ... a5+! the game could have continued like this:
16. ... a5+ 17. Kc5 Qe7+ 18. Kd4 bxc4 19. Nxc4 Rad8 20. Re1? (See position below.)
How black could have won after 20. Re1?

Ich bin gerade dabei, auf dem Schachserver chess.com eine Partie zu spielen, bei der jeder Spieler eine Bedenkzeit von drei Tagen pro Zug hat - man könnte das als das Gegenteil von Blitzschach bezeichnen ... :)
Man muss sich darüber im Klaren sein, bei solchen Langzeitpartien auf die Fairness des Gegners angewiesen zu sein, weil niemand sich hundertprozentig sicher sein kann, dass der andere Spieler nicht möglicherweise an kritischen Stellen Schachsoftware zu Hilfe nimmt.
Im vorliegenden Fall war das jedenfalls nicht so: Die Partie verlief völlig verrückt, weil mein Gegner, dem das hoch anzurechnen ist, mit den schwarzen Figuren mit allem angriff, was er hatte. Hier ist der bisherige Verlauf (die Partie ist noch nicht beendet):
1. f4 e5 2. fxe5 d6 3. exd6 Lxd6 4. Sf3 Sf6 5. d4 Sc6 6. e4 Lg4 7. d5 Lxf3 8. gxf3 Sxe4 9. fxe4 Dh4+ 10. Kd2 Lf4+ 11. Kd3 Sb4+ 12. Kc3 Lxc1 13. Dxc1 Dxe4 14. Lc4 O-O 15. Kxb4 b5 16. Sa3 c5+ 17. Kxb5 Tfb8+ 18. Ka5 De7 19. c3 Dc7+ 20. Ka4 Dd7+ 21. Lb5 Txb5 22. Sxb5 a6 23. b4 axb5+ 24. Kb3 Dxd5+ 25. Kb2 cxb4 26. Td1 Dc5 27. Dd2 h6 28. cxb4 De5+ 29. Kb3 Dc7 30. a3 Dc4+ 31. Kb2 *
Der Nebel hat sich gelichtet, und, wenn kein Wunder geschieht (also z. B. ein Blackout meinerseits), werde ich mit Weiß gewinnen.
Allerdings hätte Schwarz besser spielen können. Hätte er nicht 16. ... c5+, sondern 16. ... a5+! gezogen, wäre ein möglicher Verlauf folgender gewesen:
16. ... a5+ 17. Kc5 De7+ 18. Kd4 bxc4 19. Sxc4 Tad8 20. Te1? (Siehe Stellung unten.)
Wie hätte Schwarz nach 20. Te1? gewinnen können?

That's an honor - thanks a lot! :)
The move that sticks out for black is Rxd5+ pulling the king deeper into enemy territory.
The forced sequence is:
..., Rxd5+
Kxd5, Rd8+
Kc6, Qd7+
Kb7, c6+
Kb6, Rb8+
White cannot defend against mate at this point, with mating threats like Qb7, Qa7 and Qd5 regardless of where the white king moves next.
White could try to delay it by moving Ka6 instead of Kb6 but the position is exactly the same after ..., Ra8+, Kb6, Rb8+.
Edit: An alternative line that's also interesting,
..., Rxd5+
Kxd5, c6+
With the idea of opening up lines for the queen and rook.
You are right that 4. ... c6+ wins, but because of 5. Ka6 it is not the fastest possible win. :)
Actually 4. ...c5+ wins faster because after 5. Ka6 Qc6+ is possible, and after 5. Kb6 follows 5. ... Rb8+ 6. Kxc5? Rb5#.
The question stays how/if to win after
?
Now white's king have to shift between d and c-file. Moving king onto b-file is a mistake because of Qb4. Goal of black now is to get the queen to d5 square through tempo checks. Note that king cannot escape. For example, say king gets to d2 somehow, black can always give check with queen on d-file forcing king back onto c-file.
Once black has Qd5 and Re6, that's just a classic mating net, Rc6+ and Qb5+ etc. since the queen and rook are no longer tripping over each other. The moment black forces the white king onto b-file mate is going to follow.
There's also mate with c6 pawn if white doesn't play accurately.
Correct until here. I can tell you there is a much faster win than 4. ... Re6+ 5. Kc4 ...
Not sure, but this might be it:
Then either:
Or
then either
or
Good catches. Let me think here...
or
You are close, but ...
Qxd6 I think is a mistake, White doesn't have to move Kc4, he also has Ke4 now because black's queen is no longer guarding the e-file. You'll end up chasing the king to the wrong side of the board giving white a chance to defend w/ his other pieces.

Awesome master of chess,
@jaki01,
In my school times i was a good chess player and with the busy life I really forget this. Not I tried to solve this round and failed. Thanks for your article I have understood, I have actually missed something from my childhood! It's time to join the chess.com!
Thanks dude!
Cheers~
Yes, why not? Play again ...
nice game @jaki01 my family loves chess game
Have fun :)
This is hard.
1.Re1 Rd6
2.Kxd5 Rd8
3.Nd6 Rxd6
4.Kc5 Rb6
5.The king can move to d5, d4, or c4. Any of the three, and the black queen and rook can back the king into the h1 corner with no interference from the white queen or rook.
5. Txe7
4... Re6?
Re6+ is the second best move and wins as well, but not as fast as Qd7! (see solution above). :)
cool, thanks :-)
crap, it was late. I'll solve it.
bump me if you want to play, there is blitz and standard 20 minute games, there are many options for playing.
Normally I prefer 2 + 1, 2 + 0 or 3 + 0.
What is your user name there?
same as here. Yeah I play blitz mostly, although you make more mistakes in the rush of it.
Thanks for he information !
thank for sharing @jaki01
