How to "bore your opponent to death"? “The Caro-Kann has often been maligned for being dry and boring, played by those wishing to bore their opponents to death.” – IM (WGM) Jovanka Houska
Are there other defenses in which black can bore white to death? For example, when white starts with

1. d4.
The English Opening.
The Reti Opening.

Other than the opening choice, are there are other strategies if black wishes to bore white to death? How about if white wishes to bore black to death?

The London system (for White), the Caro-Kann and the Classical Slav with ...Bf5 (for Black), are extremely similar, we are aiming for the same setup (c3, d4, e3, Bf4, Nf3, Nbd2, 0-0, h3, Bd3 or Be2) in all of them, so they fit well together in a repertoire, and they all have the reputation of being extremely boring, especially the Slav Exchange variation that has an extremely high draw percentage and the London system that is nicknamed "the boring system" and "the old man variation".



Other openings that are considered to be boring are the French Exchange variation (1.e4 e6 2.d4 d5 3.exd5) and the Petrov (1.e4 e5 2. Nf3 Nf6).

Generally, the openings that are considered boring are either the openings that have a high draw percentage because they are symmetrical (Slav Exchange, French Exchange, Petrov) or the openings that are very positional, slow, quiet, solid, safe, passive, unambitious (London system, Caro-Kann).
