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

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

Correct.

Okay... no open puzzles, so here it goes:

White to move and be in winning position.
