The tricky notion of opposition in Chess

 In following King and Pawn ending, Black has an extra pawn with White to move. If the opposing Kings have 1 or 3 or 5 squares between on a file, rank, or diagonal then side that just moved is said to have the opposition. Weaker chess players sometimes believe having the opposition is tantamount to winning the chess game.


The following diagram harshly refutes that ignorance. Observe that if White plays King to the f1 square,  he has the opposition with Black King places at d1. 

Now take a look at the following diagram that arose from 1. Kf1 Kd2  2. Kf2 where one observes that White still has the close opposition, BUT is losing after Pawn to g4! jettisoning the Black center pawn to its Queening square at e1!  Its clear that this kind of close opposition SUCKS! Note that the e pawn checks the White Monarch in this variant which is a vital tempo allowing Queening well before White's g pawn. 

Enter our Lord and savior DISTANT OPPOSITION  with the move Kh1 in the corner 3 squares from Black King! Now if Black plays Ke1, White plays Kg1 where g4 tactic does not work and the game is drawn after a variation involving mutual queening!  Close opposition was correct here only because of concrete analysis not some blind adherence the 4 syllable O word. Orgasm has three syllables you perverts. 

Understanding when to implement distant opposition will save you many half points!!!

Also be careful about adhering blindly to geometric motifs like “Putting your King on a square which constructs a rectangle with the other King where the corners of the rectangle are the same colored square (such as a dark square), with the usual "let the buyer beware" of no pawns interfering/between the Kings"
