It is International Master-level without tree search. Good amateur
International masters are emphatically not amateurs. Indeed, IMs are at the level where they can offer coaching services to amateur players, and reasonably expect to be paid something on the order of $100 per session. To elaborate on this point:
there are >1000 players in the world that are better.
The total number of FIDE-rated chess players is over 500,000. The number of IMs, meanwhile, totals less than 3,000. IMs are quite literally in the 99th percentile of chess ability, and that’s actually being extremely restrictive with the population—there are many casual players who don’t have FIDE ratings at all, since only people who play in at least one FIDE-rated tournament will be assigned a rating.
