Problem n.1 is one of my best KoBul Kings composition - clear position, good fairy play and nice Ideal specific fairy mates. Problem n.3 was the first composed combination of KoBul Kings and Take & Make. Problem n.2 is my second combination of these fairy conditions and I like the dinamical play all over the board.

Indeed N.1 is a beautiful problem showing nice underpromotions and surprising mates by the black queen. I like the twin also !

Nice problems and nice condition. Here is my recent composition in Kobulkings:
White Pa2 Pb2 Pc2 Pd2 Pe2 Pg2 Ra1 Sb1 Bc1 Qd1 Ke1 Bf1 Rg1
Black Ra8 Sb8 Bc8 Sg8 Rh8 Pa7 Pb7 Pc7 Pd7 Pf7 Pg7 Ph7 Bc5 Kh2
Proof game in 8.5, Kobulkings

Thank you Paul! Is it published or original?
+2 #5 paul raican 2013-10-11 12:32
It is original, but is made just for fun.
+2 #6 paul raican 2013-10-11 14:36
It is made just for entertaining. Here we have a King circuit.
+2 #7 Diyan Kostadinov 2013-10-12 00:26
Please give us the solution
+3 #8 paul raican 2013-10-12 20:52
Solution: 1.Sf3 e5 2.Sh4 Qxh4 (wK=rS) 3.Kf3 e4+ 4.Kxh4 (bK is royal Q) Ke5 5.Rg1 Kxh2+ (wK=normal) 6.Kg4 e3 7.Kf3 exf2 8.Kxf2 (bK=normal) Bc5+ 9.Ke1.
wK circuit.

Thank you Paul! It looks nice! I believe that also in classical Retro genre can be found many interesting effects with KoBul Kings (such as tries or dual-avoidance effects because of Kings transformations).
+4 #10 Kostas Prentos 2013-10-13 23:47
Nice idea, but cooked, using parts of the intent:
1.Sf3 e5 2.Rg1 Qh4 3.Sxh4(bK=rQ)e4 4.Sf3 e3 5.Se5 rQxe5(wK=rS) 6.Sc3 rQxh2(wK=K) 7.Sb1 exf2+ 8.Kxf2(bK=K) Bc5+ 9.Ke1
+3 #11 paul raican 2013-10-14 13:48
Good eyes, Kostas! I have not yet a correction....
+3 #12 paul raican 2013-10-14 18:12
This is not a correction, but another game:
1.d3 Sh6 2.Bxh6(bK=rS) gxh6(wK=rB) 3.rBc3 h5 4.rBxh8(brS=rR) Bh6+ 5.rBe5 rRg8 6.g4 rRxg4(wrB=K) 7.Bg2 Qg8 8.Bc6 bxc6(wK=rB) 9.rBxc7(brR=K) Ba6 10.rBa5 Bc4 11.rBe1 Bxa2(wrB=K)
+4 #13 Kostas Prentos 2013-10-20 07:11
A small change in the move order cooks this one, too:
1.d3 Sh6 2.Bxh6(bK=rS) rSf6 3.g4 rSxg4 4.Bg2 gxh6(wK=rB) 5.rBc3 h5 6.rBxh8(brS=rR) Bh6+ 7.rBe5 and the rest is the same.
+3 #14 paul raican 2013-10-20 19:07
Thanks, Kostas! Your cook gave me the idea to make the circuit faster: 1.d3 Sh6 2.Bxh6(bK=rS) rSf6 3.g4 rSxg4 4.Bg2 gxh6(wK=rB) 5.rBc3 h5 6.rBxh8(rS=rR) Bh6+ 7.rBe5 Qg8 8.rBxc7(rR=K) d6 9.rBa5 Bf5 10.rBe1 Bxd3(rB=K)
+4 #15 Kostas Prentos 2013-10-29 02:31
Just for the record, I was unable to cook Paul's last version. I cannot say I exhausted all possibilities, but my impression is that the problem is sound.
+2 #16 paul raican 2013-10-30 21:30
Is it possible to check this with Popeye?
+1 #17 Diyan Kostadinov 2013-10-31 21:36
Paul, if I remember correct Nicolas Dupont told me that the recent version 4.63 can do it. You can ask him.
+2 #18 paul raican 2013-11-01 19:15
The answer of Nicolas:
Non, m?me pas avec la derni?re version 4.64, non officielle. Thomas travaille dessus, il faut attendre un peu pour une bonne programation du kobul et du retour...
