Eric Rosen 'blunders' into a beautiful checkmating pattern
Black to play and gain a big advantage. White played one of the worst moves as a result and Eric found checkmate in 5 from here after white's response fell into the trap.
(Technically there's another strong winning move, according to the engine, that Eric didn't play, that isn't quite as strong, but is basically the same move)
As a bonus, a rare glitch in the lichess engine is findable if you paste the FEN from the above position into the analysis board. Play black's best move, and the engine thinks an illegal move is white's best next move. 3rr1k1/pp3pp1/4b2p/2n5/8/4QN2/Pq2BPPP/2R2K1R w KQq - 1 2
