2...Rxd6?? will allow white to give perpetual checks and escape with a draw, I think:

1. Rd6 Qh2+
2. Kf1 Rxd6
3. Qe3+ Kh7
4. Qe7+ Kh8
5. Qe8+ Kh7
6. Qe7+ Kh8

or

1. Rd6 Qh2+
2. Kf1 Rxd6
3. Qe3+ Kg7
4. Qe7+ Kg8
5. Qe8+ Kg7
6. Qe7+

RE: Better move

cybstorm, what is your response to perdurabo's drawing lines? Please don't just make a statement without backing it up with moves. Nobody gains understanding with only a statement. Thanks.

Then what do you say about
3. Qe3+ Kh7
4. Qe7+ Kh8
5. Qe8+ Kh7
6. Qe7+ Kh8
or
3. Qe3+ Kg7
4. Qe7+ Kg8
5. Qe8+ Kg7
6. Qe7+

White can draw by repetition.

RE: Better move
The point of the exercise of chess tactic is not to win the game but rather to gain the maximum advantage.

With the following:

1. Rd6 Qh2+
2. Ke3 Rxd6

Bottom line, Black wins a rook and white cannot win and cannot do better than a draw - reason being that Black is one move away from mate with Rd1#. And if you were Black playing a much stronger player, a draw is a great outcome. Hence, a good tactic to force White to a draw. At the end of the day, the game seemed to be equally fought, and the outcome is near.

Many players think that a draw is a lost, in some cases it is the difference between making it to the next round of the tournament, especially when playing a stronger player. In either case, you have proven your worth, demonstrating respect to the other player by way of agreeing to the draw. Neither of you have lost.

My point is equally valid... I declare a draw. Nobody wins, it's a draw!

If it throws away a win for a draw. White wins a rook with both moves. But only Rxd6 allows white to draw by perpetual check.

RE: Better Move

I can agree that your move Rxd6 leads to a "gain" in material (White's rook) for Black and by the same move avoids a draw by perpetual check, and finally, have a chance for a win... But Black cannot force that win... the outcome is therefore not guaranteed... Although I agree that Black has the advantage, it does not guarantee a win... Two Queens in an end play... is a lot of material left to overturn the game... If you are basing your win, on ensuring that Black plays without error... then I agree...otherwise, you are risking it.

I can also say that if I was in a tourny, and a draw was all I needed to pass to the next round... I would try and risk for a win... I would take the draw and shake my opponents hand. Having said this, I can agree that if AND ONLY IF, a win was what I needed, then I would risk it for the win.

In the end, my proposition guarantees an outcome - a draw at a minimum, and even potentially a win, if White plays recklessly!

RE: Better Move
Correction #2:

The above last post was related to your Qxd6...

Also, here is an interesting and subtle variation for a White to escape for a win with Rxd6...

Here is a variation where White the Black's King escapes the perpetual check...

1. Rd6 Qh2+
2. Kf1 Rxd6
3. Qe3+ Kh7
4. Qe7+ Kg8
5. Qe8+ Kh7
6. Qe7+ Kh6
7. Qe3+ Kg7
8. Qe7+ Kg8
9. Qe8+ Kh7
10. Qf7+ Kh6 - This is the error that White's Queen makes... Qf7+
11. Qf8+ Kg5
12. Qg7+ Kh4
13. Qe7+ Kh3
14. Ke1 Qg1+
15. Ke2 Qg2+
16. Ke3 Qd2+
17. Ke4 Qd4#

Why would white play "10. Qf7+"? 10. Qe7+ serves just as well and is the better move. And now threefold repetition is in sight.

While being up a rook isn't a guaranteed win (you still have to play accurately), it's still a big enough advantage.

Agreed... White plays recklessly with Qf7!

In the end, my proposition guarantees an outcome - a draw at a minimum, and even potentially a win, if White plays recklessly...

For me this tactic is about ensuring Black a draw.

Agree to disagree?

"Never drown in a tea cup" and " He who fights and runs away lives to fight another day".(Turkish proverb) i.e. Take the draw, why risk it? It's just a game with many what ifs!!
