Three Checks Chess

|
Three Checks Chess is a variation of chess, in which additionally to usual winning condition (checkmate), you also win if you check your opponent three times.
Three Checks Chess is mentioned in Pritchard's book Popular Chess Variants. Karpov is said to excel in this chess variant.
This chess variant is much more tactical than standard chess, sacrifices are very common, there are a lot of traps in the opening. Two checks is already a big advantage and may be worth more than one piece. The game rarely reaches endgame, usually it is decided before queens are traded.
Example game: 1.e4 e6 2. d4?? (this usual openings in standard chess immediately loses in Three Checks Chess) 2....Bb4+ (first check) 3.c3 Bxc3+! (second check) 4.Nxc3 Qh4! (see diagram). White resigned (there is no way to prevent a third check by Qxf2+ or Qxe4+).
