You da man Sz! you're 3 for 3 on my puzzles.

Pooh, your puzzles are very forcing since there is always only 1 candidate move to analyse, so they are quite easy to solve.

Ok, this one is quite tricky, so make sure you analyse all the variations:

White to move, find the best move and continuation:

Since e5 fails on f5
1 Rf6 seems like a plan
...Bxf6 2.e5 with mate on h7
...bxc3 2.e5 h6 3.Rxh6 with mate afterwards.
...h6 2.e5 with a similar mating plan on h7
...Nxe4 2. Nxe4 Bxf6 3. Nxf6
...Nxe4 2. Nxe4 and after any other move by black Nf6 with the attack on h7 looks like a winning attack


although i might have missed something

Edited 5/8/2014 18:28:53

its probably harder than this....

1 e5 h6
2 exd6 dxc3
3 Qf5

Sze, just RF6 and white wins.
if Bxf6 e5 and blacks becomes checkmate.

After 1. Rf6 h6, just take the Knigt with Rxd6 looks good. anyway on sze's variation:
2. e5 Nf5? Qxf5 no?

(Relized B3rz3..) got it, anyway here's my puzzle from the other time:


Black to move

Edited 5/8/2014 20:57:18

Rf6 is the move, what happens after 1. Rf6 h6 2. e5 Nf5?

@sze Qxf5

@hennns
Qxf2 looks like a winning sacrifice
Qxf2 2. Rxf2 Re1+ 3 Bf1 Rxf1+4 Kg2 Rxf2+ with mate or material advantage a few moves later.
Qxf2 2. Kh1 Qxf1+ 3.Bxf1 Bb7+ 4. Bg2 Re1+

Edited 5/8/2014 22:17:18

it's not matirial advantage.. you gotta gice me the mate :p

"Qxf2 2. Rh1 Qxf1+ 3.Bxf1 Bb7+ 4. Bg2 Re1+"
This part is wrong.(not saying it doesn't win, but there's a better option)

I dont see the faster in the second variant.
In the first one
Qxf2 2. Rxf2 Re1+ 3 Bf1 Rxf1+4 Kg2 Rxf2+
5.Kh1 Bb7+ 6. Kg1 Rf6#
5.Kh3 Bf1+6. Kg4 h5+ followed by Be2 and Bf6
or
6 Kh4 Bf6+ and mating after Be2 or h5 and Be2

yeah, that's good enough :)

(first one, simply 2...Bxf1 is quicker)

Next one:


White to move and win.

1 e7 Bc5
2 e8->Q+ Bf8
3 Qxfx#

alternatively
1... Rh6+ just delays the inevitable
2 Kxh6 Kg8
3 e8->Q+

What about 1. ... Re3?

e7 Re3
Rb4
?


Not sure how black would continue then :/

Bf2!! Bxf2
e7 Re3
a7. White is going to queen and subsequently win the game.

After Bf2 Black can't protect the bishop as the trade leaves whit with two passed pawns, making one of them a queen. Moving the Bishop away also fails to stop white from queening.

Essentially Bf2 solves the problem of Re3 by trading of one of Blacks pices (or deposesend it), thus giving Black only one piecs to stop two Pawns.

@un theBest Bf2 is the move I was looking for and noticing that Re3 blocks the bishop on f2 the main idea.


@timinator after e7 Re3 2.Bb4 black still controls e8 and a6 so white cannot promote.
I think Kg8 wins after 2 Bb4, since Black can start running with its f and g paws and after 3 Kg6 Kf7 wins the pawn.

Note: King on G1. (as sze pointed out)



White to move

Edited 5/10/2014 14:00:47

I'll assume white king is on g1 :)

1. exf6 Qxe2 2. f7+ Kh8 3. Bxg7+ Kxg7 4. fxe8=Q+

2. ... Kf8 leads to the same position after 3. Bxg7
