Subject: Testposition for all - except Junior

Author: Mihaly Szalai

I think most of the chess engines will show a positive score
(i.e. will find 4.h8=B) in this position except Junior. (We talked
about something similar earlier.)

[D]8/7p/6pP/1B4P1/pp6/1k1K4/8/8 w - - 0 1

1. Be8 a3 2. Bxg6 hxg6 3. h7 a2 4. h8=B!

You should try it with your engine.

Thanks
Mihaly

PS. After some more moves Junior is still baffled. Can you explain this?

1. Be8 a3 2. Bxg6 hxg6 3. h7 a2 4. h8=B Ka3 5. Kc2 b3+ 6. Kc1 a1=Q+ 7. Bxa1 *

New game
[D]8/8/6p1/6P1/8/kp6/8/B1K5 b - - 0 1
