Sure, but what elements ? that is the question !

This is not enough, as shown in the above "minimal" game, composed in 2
minutes :

tcf1r3/1ppp4/3fpp1c/7t/8/p7/PPPP1PPp/TCFDRFCT
24 demi-coups.	14 + 14

4.Ph6xg7   Ph7-h5   5.Pe2-e4   Ph5-h4   6.Pe4-e5   Th8-h5
7.Pe5-e6   Cg8-h6   8.Pg7-g8=C Ph4-h3   9.Cg8-f6   Pe7xf6

Perhaps that realizing this thema twice (that is 4 promoted knights by the
same side leadind to 2 cross-captures) would be interesting and new.
