Despite the wandering lifestyle, his play is anything but casual: rated 2283, Rookjoy operates at candidate master strength, calculating accurately, punishing club-level mistakes, and arriving at the board with genuine opening preparation. With the white pieces he leans heavily on the [Trompowsky Attack](/resources/openings/trompowsky-attack), an offbeat weapon he has wielded in over 80 recorded games, sidestepping mainline theory by planting the bishop on g5 at the earliest opportunity. As black he answers 1.e4 with the [Tartakower Caro-Kann](/resources/openings/tartakower-caro-kann), a solid and dependable setup. His lucky silver harmonica is never far from the board, and neither is his favorite maxim about kings, queens, and dreams. Opponents should expect an aggressive, well-prepared player who simplifies into positions he understands better than they do.","55","cTlrl","Netherlands","nl","815660f1ebc0803ba85b4e0a73b6163b3fe01f0b2544699d66c67b5ac9f94887","2026-07-06",2283,"json",[15,18,21],{"question":16,"answer":17},"What rating is Rookjoy?","Rookjoy is rated 2283, which places him at candidate master strength.

Because he attacks while trading pieces, opponents should avoid reflexive exchanges and keep enough material on the board to generate counterplay. Sharp, unbalanced middlegames offer better practical chances than simplified positions, where his 2283-level technique takes over.","Life's a game of chess, mate.
