How Antonio plays
Antonio plays sound, book openings and is the first bot many players fail to beat. Players in the 700–1100 range report beating him, which says less about their strength than about how bots at this level play: solid in the opening, then strangely passive once the position is out of book. Reviews of losses to Antonio usually show the player getting a fine position and then losing the thread in the middlegame.
The plan
Get through the opening without concessions, then make a plan — a pawn break, a piece to a better square — and keep playing it. Antonio does not punish slow, purposeful play; he punishes aimless moves.
Review the game you just lost
Bot games on Chess.com have their own address once they are finished: chess.com/game/computer/…. Type rv in front of it — rvchess.com/game/computer/… — and the full review builds itself: accuracy for both sides, every move labelled, and a graph you can click to jump to the moment the game turned. It is free, needs no account, and does not count against Chess.com's daily Game Review.
If you cannot find the address, paste the game's PGN instead. Chess.com's Game Review is limited for free members, so this is also the way to review every bot game rather than one a day.
Which move to look at
Against a advanced bot the useful move is rarely the last one. Open the review, find the first place the graph tips against you, and ask what Antonio was threatening there. That is the pattern to fix; the final blunder is just where it showed up.
