### Emmanuel Manolas (2)

The problems we see here belong to Fairy Chess, because they all have the condition Madrasi, (which is my favourite).

Madrasi : Opponent pieces of the same type are paralysed when they threaten one another. Each piece loses all other properties and keeps only the power of paralysing the opponent similar piece. Each piece regains all its properties at the moment the threat is interrupted.

The condition took its name from the city Madras of India, from which came the famous composer Abdul Jabbar Karwatkar. We will see first an excellent problem of his.

 (Problem 261) Abdul Jabbar Karwatkar, First Prize, The Problemist 1983, Mate in 2. Madrasi condition. #2, Madrasi, ( 11 + 10 ) [6Rr/bR1P3k/1Ps1BP1b/qrB1SPp1/1p1KS3/p7/8/8]

Key : 1.Bf8! (bBh6 is paralyzed, the threat is [2.Se4xg5#], but the wK is exposed to four checks)
1...Qxb6+ 2.d8=Q#
1...Rxe5+ 2.d8=S#
1...Rd5+ 2.d8=R#
1...Bxb6+ 2.d8=B#

The problem shows the four promotions (it is an Allumwandlung (AUW) problem).

We see next original Madrasi problems by Manolas Emmanuel, (you may also see a Retro Madrasi 5-mover already presented here).

 (Problem 262) Manolas Emmanuel, original, Mate in 2. Madrasi condition. #2, Madrasi, (5 + 3) [1K1krb2/8/5S2/3S4/1B6/8/8/4R3]

Tries : {1.Ka8? / Ka7? Kc8!}, {1.Sf6-g4? / Sf6-h5? / Sf6-h7? / Sf6-g8? / Sf6xe8? Kd7!}, {1.Sf6-d7? Kxd7!}.

Key : 1.Sd5-e7! [2.Se7-c6# / Ba5# / Rd1#]
1...Bh6 2 Se7-c6#
1...Rxe7 2 Ba5#
1...Bxe7 2 Rd1#

With the key three threats are introduced but later they are separated.

 (Problem 263) Manolas Emmanuel, original, Mate in 2. Madrasi condition. #2, Madrasi, (6 + 5) [5krb/3K4/2S4S/7p/R6r/8/1B6/6R1]

Tries : {1.Kc7? (zz) / Kd6? (zz) / Kc8? (zz) / Ke6? (zz) Ke8!}, {1.Sh6-f5? (zz) / Sh6xg8? (zz) Kf7!}, {1.Sh6-f7? (zz) Kxf7!}.

Key : 1.Sc6-d4! [2.Sd4-e6# / Ra8# / Ba3#]
1...Rh4~ 2.Sd4-e6#
1...Rh4xd4 2.Ba3#
1...Bh8~ 2.Sd4-e6#
1...Bxd4 2.Ra4-a8#

The key cuts two lines of paralysis with triple threat, but in the variations only one of the threats is valid.

 (Problem 264) Manolas Emmanuel, original, Mate in 18. Madrasi condition. #18, Madrasi, (10 + 11) [krQR2rb/2p4p/q1b4P/K1p2p2/2P2P2/1R2p3/4P3/B6B]

In this more-mover problem the bK has minimum mobility and the wK has the ease to go and free its piece which will give the mate.
We show only the moves of the White.

Key : 1.Ka4! 2.Ka3 3.Ka2 4.Kb1 5.Kc2
6.Kd3 7.Kxe3 8.Kf2 9.Kg3 10.Kh4
11.Kg5 12.Kxf5 13.Ke6 14.Kf7 15.Kxg8
16.Rd8-d2 17.Rd2-a2 18.Ra2xa6#

 (Problem 265) Manolas Emmanuel, original, Mate in 3. Madrasi condition. #3, Madrasi, (7 + 5) [3k4/1p1P2p1/P2K1P1b/3R4/8/3R4/2B4/3r4]

The plan seems to be simple : One wR will sidestep to threat mate, the bR will stop it and then the other wR will be interposed... Let us see :

Try : {1.Rc5? Rc1!}.
Try : {1.Rc3? Rc1!}.
Try : {1.Re3? Bxe3!}.

Key : 1.Re5! [2.Re8+ Re1 3.Rd3-e3#]
1...Re1 2.Rd3-e3 [3.Re8# / Ba5#]
___2...Bxe3 3.Re5-e8#
___2...Bf4 3.Ba5#
