If you are familiar with promotion puzzles, you will know what you are looking for here in a general sense. This is a very special kind of promotion puzzle. After you solve it, can you see what is special about it? One last thing- the FEN is important here- pay attention to it.
All promotion puzzles have underpromotions as a theme, but this one was special in that white promoted pawns to all possible pieces from queen right down to a knight. That is unusual.
The theme was underpromotion.
The required solution ends at move 11 for white. Well done, so what is very special about this promotions puzzle? In other words, what was the theme?
It's a win for white. I like playing simple positions that's why I made 24th move.
Alena, it has never been clear to me if black can transpose the moves here to reach this stalemate theme. The main line queens the g-pawn first, and the composer gave 5. ....g1(Q) the exclamation point, so the composer thought 5. ....Rc2+ was probably inaccurate, or led to an uninteresting win for white. However, after 5. .....g1(Q) 6.Rxg1 Rc2+ 7.Kb1 Rb2+ 8.Ka1 Kc2 9.d8(Q) Rb1+ 10.Rxb1 Bd4 11.Qd4 stalemate is the main line. So, from this you need to find the method white must use to avoid the stalemate.
Yancey, I have found the stalemate but it will be hard to overcome it.
Did you mean this variation?
You have to think outside the box on this one for both sides of the board. I will give you hint that black has stalemate themes in mind that white has to overcome.
Alena, you are correct right up to move 5 for white. Black has a better defense than 5. ...Bc7. I will check back tomorrow and see if you have found it.
At first I thought it was impossible to win. I found five moves and I was stuck. I couldn't guess the sixth move for a long time.
It's a win for white but it's difficult to win.
