			<description><![CDATA[Complete cycle with 3 elements requires 3 phases, 4 elements 4 phases etc.. Complete 4-fold cycle is quite an achievement. Lachny cycle in 2 phases with 6 elements is probably easier than a complete 4-fold cycle, but I know little about it. I just wished to draw attention to unification of the thematic elements into single, well balanced dynamical mechanism. Actively or passively, all thematic pieces participate in the cyclically changed distribution of the same thematic functions. And without changing the original author's content. I did make several versions with less pieces in total, including the one which you presented. But I chose the one which shows O/D moves by wQ with D/O pins and without white Pawns. One wP which guards 2 flights instead of 2 black selfblocks might be OK, but a wP which only reduces mobility of wQ is less desirable. I didn't like: W:Rg7,Pc4,Bg4,Ba3,Ph3,Kb2,Qa1 B:Pd7,Sf7,Kf6,Ph6,Se5,Rf4 ,Pf3,Pc2]]></description>

			<description><![CDATA[Surely, your version of n.317 is much better than original one. But the cycle is not completed as you wrote, since wBg5 does not mates. May be 3b1nR1/5k1p/3pn3/1Bp2rB1/1QPp1p1K/8/8/8 looks more aesthetically?]]></description>

			<description><![CDATA[Vitaly, complete reciprocity of wR/wBg5 would close their own circle and their functions would not be transferred to other pieces. Such reciprocity is missing in the original scheme but the functions are cyclically distributed to wR,wBg5 and wBb5: pin, guard and mate. Cyclic change of functions makes a more complex mechanism, even when the cycle is not completed (when all pieces execute all functions). The cycle of 3 white pieces is present in the original but the pin of bQ can't be transferred to wQ. And that's the benefit of bRf5/bSe6, the pin of the particular piece (bR/bS) includes wQ into the cyclically changed functions of 4 white pieces. The whole line of the functions is shifted in the 2nd solution with the last link (pinbR) shifted to 1st position (wQ). So, the line is actually closed into a circle. pinbS-mate-guard-pinbR -wQ----wR---wBb5-wBg5 pinbR-pinbS-mate-guard]]></description>

			<description><![CDATA[Nikola, the mechanism (your version of n.317) would be perfect if there will be a clear function permutation of WRg8/WBg5. WRg8 is a static pinner in one phase and it mates in the other phase. WBg5 is a static pinner in one phase and it guards flights in the other phase. So, it is a slight imperfection, on my glance. But your understanding of a mechanism is perfect, I think :-)]]></description>

			<description><![CDATA[A completely unified dynamical mechanism is what I search for in the realization. Any artificial addition of some "external" and self-justifying mechanism, is "technical" in the essence. Especially when the parts/pieces of that external mechanism have functions only in one phase. So called "unified/matching solutions" don't impress me if the MECHANISM is not unified. But a good original mechanism is always interesting.]]></description>

			<description><![CDATA[It is the dynamics which unites all thematic pieces (parts) into one single mechanism. Activity of these pieces or the change of their static functions creates the dynamics. W:Rg8,Bb5,Bg5,Qb4,Kh4 B:Bd8,Sf8,Kf7,Ph7,Pd6,Se6 ,Pc5,Pd5,Rf5,Pc4,Pd4,Pf4 H#2; 2.1.1.1. 1.Rf6 Qe1 2.Ke7 Rg7#; 1.Sg7 Qb1 2.Kg6 Be8# Now, wQ must pin the different pieces, in each phase the piece which has a selfblock function. But that piece has the line-closing (+ different selfblock) function in the other phase. The reciprocally changed functions of bRf5/bSe6 involve wQ into the dynamics of the whole unified mechanism. Transfer of the functions between the phases which links white pieces: wQ=pin1-(bS)-pin2=wR=mate1-mate2=wBb5=guard1-guard2=Bc5=pin1-(bR)-pin2=wQ]]></description>

			<description><![CDATA[White pieces Rc2,Bc5,Bf3 function in a cyclic mechanism, pin-guard-mate. This cyclic change makes Bc5 an intrinsic part of the mechanism, despite its apparently static functions. The dynamics of Bc5 is achieved through the changed function. bQ is active and together with active bK, it creates the thematic relation with the white mechanism. However, bQ has the same function in both phases and despite the obvious activity, this dynamics may still look as a "technical" move, added to the scheme h#1: W:Kd6,Bc5,Bf3,Rc2;B:Bd4,Pf4,Pb3,Sc3,Kd3,Pd2,Pf2 Well, now you may ask what do I want. If I claim that everything is artificial, then why not this h#1: (III) W:Kd6,Bf3,Qb2; B:Pf4,Kd3,Pf2 The true question is, what makes a unique, functional and economical MECHANISM? -Continued in the next comment-]]></description>

			<description><![CDATA[I'll try to explain better my comment to no.317. A good scheme and thematic content could be realized more or less convincing. The functionality and economy of the MECHANISM is very important. Mechanism should be dynamic, static elements are not a genuine part of a mechanism, although they passively support its functioning. bSf4 has no active function so why should it be on the diagram? It is a cookstopper in the first place and also gives an artificial reason for h#2. ser-h#2 would spare 7 pieces: (I) W:Kc6,Bc5,Bf3,Rc2; B:Qb4,Pf4,Pb3,Kd3,Pd2,Pf2 The extension of this ser-h#2 is achieved with bSf4 and wQ which perform the pin. But bS+wQ make a completely independent additional (half-static) mechanism. The main mechanism can work without it, as (I) clearly shows. Therefore, the added introductory moves by wQ are only "technical" in their true nature, although they may look as thematic to someone. -Continued in the next comment-]]></description>
