that the annotator believes the move to be dubious or questionable but to possibly have merits. The "?!" may also indicate that the annotator believes the move is weak/deserving of criticism but not bad enough to warrant a "?". A sacrifice leading to a dangerous attack that the opponent should be able to defend against if they play well may receive a "?!". Alternatively, this may denote a move that is objectively bad but sets up an attractive trap. !? (Interesting move) The "!?" is one of the more controversial symbols. Different books have slightly varying definitions. Among the definitions are "interesting, but perhaps not the best move", "move deserving attention", "enterprising move" and "risky move". Usually it indicates that the move leads to exciting or wild play but that the objective evaluation of the move is unclear. It is also often used when a player sets a cunning trap in a lost position. Typical moves receiving a "!?" are those involving speculative sacrifices or dangerous attacks that might turn out to be strategically deficient. Andrew Soltis jokingly called "!?" the symbol of the lazy annotator who finds a move interesting but cannot be bothered to work out whether it is good or bad. ! (Good move) An exclamation point ("!") indicates a good move—especially one that is surprising or requires particular skill. The symbol may also be interpreted as "best move". Annotators are usually somewhat conservative with the use of this symbol. Reasons for awarding the symbol vary widely between annotators; among them are strong , well-timed breakthroughs, sound sacrifices, moves that set traps in lost positions, moves that avoid such traps, and good psychological choices in the opening. !! (Brilliant move) The double exclamation point ("!!") is used for very strong moves, usually difficult-to-find moves which require a high level of skill and calculation. Examples include sound sacrifices of large amounts of material and counter-intuitive moves that prove very powerful. For example, in what is known as the Game of the Century, annotators typically award a double exclamation point to 13-year-old Bobby Fischer's move 17...Be6, sacrificing the queen. Others A few writers have used three or more exclamation points ("!!!") for exceptionally brilliant moves. For example, when annotating Rotlewi–Rubinstein 1907, Hans Kmoch awarded Rubinstein's 22...Rxc3 three exclamation points. Likewise, an exceptionally bad blunder may be awarded three or more question marks ("???"). The majority of chess writers and
