here is another one that seems pretty fair
very interesting material imbalances

(@1st) Without covering the diagonals white would suffer quite hardly of the imbalance until the king is broken. Imho the two extra dev. moves don't change anything on that.
(@2nd) could be interesting to find out
I have been experimenting with a few different material imbalance positions for practice/entertainment What do you guys think? here is one of them
had to give white 2 extra development moves or it was just too difficult to get the rooks coordinated in time against good players.
