I have defeated three of the highest-rated Komodo engines at bullet on chess.com via the following bug.

After the moves

1. e4 e6 2. d4 d5 3. Nd2 Nf6 4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 7. Ne2 cxd4 8. cxd4
f6 9. exf6 Nxf6 10. O-O Bd6 0-1

... they (white) reach the obviously correct conclusion that I have known all my career, that white is busted, and time out.

The highest-rated engine I have beaten without this bug was Komodo19 (2325) which in the following position:

3rr2k/pp2q1p1/2p2p1p/2P5/PP1Q1Pb1/4P3/1B3K2/RB3R2 w - - 0 24

...played 24.Bg6? blundering its queen. (The non-topline engines have a certain blunder rate built in but in this case it must be a low one given its rating.)
