The Siege of Goiky

During the vastness of the 1800s, the French sieged the Goiky Republic and turned it into a French colony, like what they did to Vietnam. Now, the siege of Goiky turned into a tactic in chess. I beg you to review the game from that move.

The Siege of Goiky is when there are two or more Alekhine's guns are fighting for a piece of the defender. The attacker manages to outsmart the defender, eliminating most of his/her defending minions. Otherwise, it's called a failed siege of Goiky. It is strong against most pins, forks and skewers, but weak against 2-way Alekhine's guns (an Alekhine's gun but with two directions (ex. two rooks and a bishop)). So don't siege against Alekhine, he can easily counter it!

Here's another example of the siege of Goiky:
