One such problem does in fact come close to my aspiration to find problems with game-like positions. This is a mate in 6 problem published in the (then) Yugoslav magazine ‘Mat’ in 1978, where it received 4th Prize:
A lovely mate in 6 from 1978. Answer below.
It’s only when you do a piece count that you think that Black might perhaps have resigned by now! Still, forcing mate in 6 seems a tall order considering the compactness of Black’s position. Perhaps the composer intends 0-0-0 to be part of the solution? Well, yes, but this is where we diverge from game-like thinking, for the reason for 0-0-0 turns out to be nothing to do with mobilizing the a1R; instead, it is to make the squares a1 and e1 available for the Bishop! (Has this reason for castling ever happened in an actual game??!) The solution (and full marks if, armed with this hint, you’ve been able to visualize how this works) runs: 1.0-0-0! a5 2.Be1 a4 3.Bc3 axb3 4.Ba1! b2+ 5.Qxb2 a5 6.Qxg7!
Once you see the pattern the finish is lovely!
Here is another example of the Macleod wizardry, again from ‘Mat’, this time winning 1st Honourable Mention in 1981:
Mate in 4 with white to play. Answer below.
This time the stipulation is mate in 4. On the face of it, this should make the problem easier, and indeed it does look as though it shouldn’t be too difficult to mate Black in that timescale – indeed, the surprise might be that there is only one way to do this (a prerequisite of this being a sound problem).
The difficulty though is that the black Bishop is a desperado – if it is captured then we have stalemate. If 1.Ra8? then 1…Bb4 and if then 2.R8h8 then 2…Be7. It turns out that the only way to do it is to play 1.Rc8!, threatening 2.Rc4 and so forcing 1…Bd4. Now we play 2.Ra8 and since any other black move fails to 3.Ra4+ Black plays 2…Ba7. Only now can we play 3.R8h8 and mate next move by 4.R8h4.
After 3. R8H8 an unstoppable checkmate is threatened wherever the black bishop moves.
