Demo # 1

15. Qh4 ...
Black To Move.
The black pawns on c8 and h8 are safe because they can not be captured.
Blacks problem however is the weak pawns on e4 and e7, these can be captured.
If black plays Qd1 then 16. Bxe4 Qxe2 17. Bxb7 cxb7 18. Qxe7 ...
White has won a pawn and the white king will be quite safe on a1 after it is deployed.

10. Ne5 f7
Note that blacks move would not be possible had the queen been automatically deployed to d8 at the start of the game due to Nxf7 winning a pawn with tempo.

White rushed for active play but black defended calmly and has a solid position.
White could have rushed g4 + g5 + g6 so black retreated the knight to trade it off as the black position is solid but a bit cramped.

In the next example direct engagement is avoided with the players keeping the position as symmetrical and as flexible as possible.
Note that the centre is stable with no immediate pawn breaks possible.
Note that when kings or rooks are about to be deployed moves are often played on the board to try and establish the position before playing a drop that commits the player.
The position on the board draws together while the kings or rooks sit on the side boards watching.
Note that the king was very late in this game but it could be first or whatever really.
