Hi Zied,
The Builder gives other pieces strong powers. If a pawn and queen are next to a builder, the pawn can act like a queen. But to limit this power, pieces usually need to move to the builder. Since the builder only strengthens other pieces (never weakens), I think overall there is move power compared to normal chess.
For this game:
5. d7-e6 (pawn using king's move)
nc7+
6...Bxc7 (bishop using king's move)
c3
7...Ke7
qh4+
8...Kd7
ke1
9...Ue8
e5
10.fxe5...Kc8
exd6
11...Bxd6
hxd6(using bishops move)
I assume you'll play Qxd6 and i'll play d4
I'll actually play 12...Nd7 (keeping my queen close to my builder).
i'll still play d4
13...Nxd6 (knight using queen move)
f2-f4
