For example, in this position, black is threatening to play ...Kg7 and Rh2. If he does, that his opponent will wind up in a lot of trouble. The question is, what is white's best move, in this position to get out of this mess. You might be shocked to find out, but I'll give everyone until tomorrow or maybe even Saturday to answer this question.

Now, this position is, most certainly based on JP's most recent quiz.
|
|
yeah i got nothing!!
|
|
Rc6? Threatening to split the two weakest black pawns? It's what I would do
|
|
While I won't give the answer, and will wait until, even tomorrow unless someone gets the right answer, I'll tell you if someone, however, is incorrect as that's a way to learn. Unfortunately, @king-nothing: Rc6 is not the solution.

@mrmarmalade
You mean Rf7. I can see where, but it's not Rf7+ either, and originally I thought it did to, but that move does not lead to mate.

I was fiddling with the analysis board for about 7 minutes
This is the best I can come up with right now
1. Re6 Kg7
2. Rxe5 Rh2
3. Rg5+ Kf6
4. Rf5+ Ke6
5. Rxf4 Rxg2
6. Rg4 Rf2
7. f4 g2
8. Ka2

If you could eliminate the rooks it's a dead draw
But white can't force a rook trade. After Kc1 white can completely sacrifice his rook. Either he get's stalemated on e2 or he can get perpetual defending g2.

@pawntificator
Interestingly enough, I thought that the solution was actually 1.Re6+, with a slightly different idea and not to win a free pawn, although that's how it would appear. But, you want to do, as noted, is to prevent black from playing ...Rh2. So, after say, 1.Re6, Kg7 (as noted earlier.) Then, this, I thought I would happen, 2.Re7+, Kh6 3.Re6+, and if 3...Kh5, as opposed to 3...Kh7, black would take a pawn and win the game. So, 3...Kh7 4.Re7+. After that, 4...Kh6, 5.Re6+. And, that the same position would occur three times, henceforth, a draw by repetition. But, that is not the correct. However, you are on the right, Kc1, but that is not quite it, but you're now very close. The question is what move can white make, that will allow him to play Kc1. Hint: what you stated in the last subject, before the actual post is correct. And, there is one move that will do that.
|
|
And
That last subject is, "If you could eliminate the rooks it's a dead draw".

OK, now I got it
Rf8 and now the King can make it to g2 in time.

Yes
@pawntificator: That is the solution because it forces a stalemate. After 1.Rf8, Rxf8 white plays the immediate 2.Kc1 After that, this would happen 2...Rh8 3.Kd1, Kg6 4.Ke2, Rh2 5.Ke1. So, despite giving up a R, or you can say being a R ahead, black has no chance, of winning in this position. That's what makes it shocking. Normally, one would think during any phase, but especially in an endgame that falling behind can seal your fate, especially in a GM game. But, that is not the case here. The idea is that giving up the rook gives white enough time to get a draw. And, tempii is essential ingredient, here. The thing to keep in mind is what IM elyhim would say. That is, "Gaining tempo is like taking money out of your opponents wallet and depositing it into your own bank." That especially applies here.

Ok
Here's another quiz. This time, it's from one of my past games. In this position, I'm black and my opponent is white Now despite white being behind in development. In this particular game, I played poorly, and did not do a good job in developing, either and the center was not controlled. In fact, the opening was quite horrible, and blundered away material, winding up two pieces behind. Trust me, this was far south of rating, even back then. So, black should lose with best play, as this hopeless. Having said that, T or F, white's best move here is 1.Qc6. Note: When you're ahead, you generally want to take advantage of your opponent. One way of doing so is exchanging, or doing what you can to win even more material so that you're opponent has even less to defend with.

F
Although it looks tempting, I found a much better move.
|
|
Correct
As it turns, out believe it or not, white actually played 1.Qxc6?? But, as it turns out, that was his losing blunder because once he took, I black was able to mate in one with 1...Qc1#.

I have another quiz. I am white, in this game and the opponent is playing black. This is based on a team game. Now, in this particular game, black made some serious blunders and wound up giving away a lot of material, until we were left with something like this. Then, I made some inaccuracies, wasting tempii, when I could have achieved a win sooner. In fact, with best play, I believe that black would have forced a draw, either by repetition or with stalemate. And, the hint is that it's a similar position to some of the quizzes that you would see from Judit Polgar. In fact, in this game black nearly forced a draw since ...Kb5 followed ...Kb6 were played twice, and the way I checked him (with the same move) repeated once. However, there are a couple of ways to get out of a draw and actually checkmate black. What is the best way to do that? In other words, what is the best move here?
|
|
Time's up
In this position, the best move is 1.Rb4+. By doing this, white does prevent the draw by repetition that black is hoping for. And, right after that, he played 1...Kc7?? which instantly lost for him because I was able to set up a mating sequence against him.

The puzzle is shown below  puzzle #116795.

This game is based on another JP quiz. Now, this one was in a tourney and the game was between GM Zee Nakamura and GM Van Wely. Now, in this game, Nakamura is white and Wely is black In this position, instead of taking, white's last move was 1.Qf4 Is this the right choice and why? BTW, to help clarify things a little it's currently black's turn to move.
|
|
The answer is that it is the right choice. If black took back with ...Qxf4, the game would end in a draw, after 1.Rh8, Kg7 2.Rg8, Kh6 3.Rh8, Kg5 4.Rh5, Kh5. Instead, black doesn't have to allow a draw, in this position. Now, he can win, after 1...Qxd8, as opposed to, the ...Qxf4.
