471 Pat a Mat 26 - September 1999

Comment on original for solving:
Miniature 471 has two variations ending in model mates with colour echo (black king stays on squares of different colour).

1.Jf5! zz,
1...Ka7 2.Jd6 Ka6 3.Sb7+ Ka7 4.Jcb5#,
1...d6 2.Jxd6 Ka7 3.Jcb5+ Ka6 4.Sb7#.

Colour echo. It is a pity that the second white move is the same in both variations. (IG)

#4 (5+2)

472 Pat a Mat 26 - September 1999

Comment on original for solving:
Next fourmover contains thematical tries 1.Qd8+? A, 1.Sf5+? B and 1.Qb8+? C. With the solution you can also changes of functions of moves (if you look hard enough...).

1.Dd8+? (A) Sd7! 2.Jf5+ (B) Kc5 3.Dc7+ Kb5(d5) 4.Ve5#, 2...Kc6!
1.Jf5+? (B) Kd5 2.Dd8+ (A) Sd7 3.Dd7 Vd6(Kc5) 4.Db5(Ve5)#, 2...Vd6!,
1.Db8+? (C) Kc6!,
1.Ve5! th. 2.Dc5+ Kd7 3.Ve7+ Kd8 4.Dc7#,
1...Sc6 2.Db8+ (C) Kd7 3.Je8! and 4.Dc7(Jf6)#,
1...Vc6 2.Vd5+ Kd5 3.Dd7+ Vd6 4.Db5# (3...Kc5(e5) 4.Dd4#, 2...Ke7 3.De8+ Kf6 4.De5#), 1...Kxe5 2.Dc5+ Kf6 3.Kxh6 and 4.Dg5#.

The fact that all tries are checking doesn't leave good impression. The change of functions seems then to be artificial. (IG)

Finally we have some studies. Ladislav catches interest by knight-bishop duel.

In Eligiusz' 474 white saves himself by demobilization.

Bloody introduction and pseudostalemate in finale. (MK)

The same method, but with different result, uses black in 475 by Ukrainian couple.
