Bishop Rivalry (1)
Queckenstadt
1922


The two Bishops were fighting their own battle, while their Kings were watching. It was all about proving suited for the elevation to Archbishop. The struggle was tense when suddenly one of the Bishops realized that he could achive his goal by actually giving himself up.

As a true religious man he did so. Transfered himself to g2 [1.Bg2!] and faced his rival. Left with no choice his shocked brother in faith entered the same square [1...Bxg2] and found himself in a deserted land. After 2.e4! the door was closed. Desperately the Bishop tried to open it again, but could he do it in time?

Test: If your program could search deep enough to find the win for white. If not, try it with 1.Bg2 played.

1. Bg2! Bxg2 2. e4!

1-0

The Goose Chase (1)
Troitzky study
1923


Hm, a bishopending with black a pawn up. But white's king is much better positioned. White's bishop is a real flyer while the black one tries to take off again and again - but never makes it... A flyer versus a goose and the hunt is just about to start.

Test: If your program is a flyer or a goose. The faster the better But the evals should show that white is *winning*

Merry-go-round (1)
A. Selesniew study
1921


So few pieces and so tricky! Here we need the Deep ones at their best! Maybe also Diep? If you play this one out you sure will get dizzy!

Test: White to move and draw. Not many choices - the black pawns are on the run.

1/2-1/2

Good bishop vs Limited knight (1)
Dawson
1925


Seemingly about equal but your evals should soon show a big + for white. In fact white is winning this position by showing the limitations of a poor placed knight.

Test: White moves and wins. The sooner your program sees it - the better. It might happen in a tournament game!

1. f7 Kg7 2. Be7 Kxf7 3. Bb4

1-0

The Winning Arrow (1)
Queckenstadt
1914


From Queckenstadt 1914 [published in Sydsvenska Dagbladet /Swedish newspaper]

Here we have a bishop ending. White is a pawn down and black has two passers. No wonder your evals show a +score for black. But they should change cause white is winning this position. His pawns c6,d5,e4,f3 resembles an arrow, and once white lets it off there is fire on the board!

Test: White to move and win - could you do that under normal tournament conditions [40/2]

1. f4 Bxf4 2. Bd4 f6 3. e5 fxe5 4. Be3 Bxe3 5. d6 cxd6 6. c7

1-0
