How the Ruy Lopez: Opening Trap (Uhlmeier–Kreutzkamp) #2 works
The Ruy Lopez: Opening Trap (Uhlmeier–Kreutzkamp) #2 is a classic chess opening trap arising from the Ruy Lopez. In this line White wins decisive material by move 9, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 5.d4 b5 6.Bb3 Nxd4 7.Nxd4 exd4 8.Qxd4 c5 9.c4. Each move looks reasonable, which is exactly why the trap is so effective over the board — Black walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Uhlmeier - Kreutzkamp, Germany 1989). Recognising it early lets you either spring it as White or sidestep it as Black.
