Title: Pinning Combination
ThreadText: # Pinning Combination
  
  (Asked by: username_0 on 2020-08-18)
  
  There are are four types of pins.
  
  Absolute Pin-A piece is pinned to the king and cannot move due to the resulting illegal check.
  Partial Pin-A piece is pinned to the king and can move along pinning line but nowhere to else due to the resulting illegal check.
  Relative Pin-A piece is not pinned to king and can move but doing so would lose the exchange.
  Situational Pin-A pinned piece can move butdoing so is dettered by a loss of material or mate.
  
  I am looking for a combination played in a real game that demonstrates all four kinds of pins, preferably in a row in any combination of the four pins.
  The best I can find is a mate in two combination with two absolute pins in a row.

  I do not know of a game that shows all four in a combination. However, here is a chess problem that I made to demonstrate all 4 types of pins in a "combination-esque" sequence.
