Hello,

Yesterday motivated me to restart the thread. In this position it is white to move:



After the tournament 2 of my chess buddies showed me this position in which white resigned due to imminent mate or queen loss. Should white have resigned?

Yes.

Qxf4
xf4
Bxf4

Then Knight and Rook can delay two turns

b8
Kb6

checkmate

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6 and black stops immediate checkmate.

im not that great at chess, but it looks to me like whites only two moves are to move the king (or bishop, to accomplish same goal) or put black in check. either way white will lose its queen.

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6 and black stops immediate checkmate.

Ah I just glanced over it.
Well then,

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6
5. Rxa6+ xa6
6. Rxc8+ Rxc8
7. Bg2 checkmate with one delay move.

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6 and black stops immediate checkmate.
5. Rxa6+ bxa6
6. Rxc8+ Rxc8
7. Bg2+ Rc6
8. Bxc6

Checkmate, white wins.

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6
5. Rxa6+ bxa6
6. Rxc8+ Kb7

and black king escapes.

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6
5. Rxa6+ bxa6
6. Rxc8+ Kb7

and black king escapes.

Then 7.Rc7+ Kb8 or Ka8

if Ka8 then
8.Bg2

if Kb8 then
8.Re-h7+ Kc8
9.b7

After Rc7+ king can take the pawn on b6 and black is up a lot of material.

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6 and black stops immediate checkmate.

nice one, hadn't thought of that

With another 5th move:

1. Qf4+ gxf4
2. Bxf4+ Ka8
3. Nb6+ axb6
4. axb6+ Na6
5. Rxc8+ Rxc8
6. Rxa6+ bxa6
7. Bg2+ Rc6
8. Bxc6

Exactly kergemarha! At first it was tricky for me to find that move order, but when you analyse the only chance Qf4+ it proves to be the only way to keep the black king in a mating net. You can post next problem or I'll post one if you don't want to.

I'm afraid, I can't post a problem. I haven't played chess for ages and I'm not really good at making up boards. :)

This one is from a recent game of mine, black to move, what's the best move?

if i was playin that agme i would stall... wait, it wouldnt just be in that agme, thats all i do in chess

1. .... b4
2. Ne2 Nxe4
3. fxe4 Bxg5

(White can't recapture on g5, and Black is now a pawn up. + Black has pressure on c2 and h4.)

Edited 10/2/2015 14:08:51

Exactly Tbest, the game went:
1. ... b4
2. Ne2 Nxe4
3. fxe4 Bxg5
4. Qxg5 Qxc2+
5. Ka1 Qxd1+
6. Nbc1 Rc2
7. Bg2 Qd2
8. Qxg7 Rxb2
9. Qxh8+ Nf8 0-1

You're encouraged to post your chess puzzle.
