The second Tarrasch Trap, sometimes referred to as the Dresden Trap, occurs in the
Steinitz Defence. Tarrasch published analysis of this trap in 1891, but 18 months later
Georg Marco fell into it in Tarrasch–Marco,
Dresden 1892. Tarrasch spent just five minutes thinking during the entire game.
1. e4 e5 2. Nf3 Nc6 3. Bb5 d6 :This is the Steinitz Defence of the Ruy Lopez.
4. d4 Bd7 :Black breaks the pin to meet the threat of 5.d5.
5. Nc3 Nf6 6. 0-0 Be7 7. Re1 (see diagram) :Laying a subtle trap.
Castling seems natural for Black but it loses a pawn. Instead, 7...exd4 is better.
7... 0-0? 8. Bxc6 Bxc6 9. dxe5 dxe5 10. Qxd8 Raxd8 11. Nxe5 :Black's best move here is probably 11...Bd7, although White would remain a pawn ahead.
11... Bxe4 12. Nxe4 Nxe4 :White can go astray too: 13.Rxe4?? would be a horrible
blunder as Black would
checkmate with 13...Rd1+ 14.Re1 Rxe1#. White blocks that possibility with his next move, making the threat real against the black
knight on e4.
13. Nd3 f5 :The black knight cannot move because of the pin against the
bishop on e7.
14. f3 Bc5+?! :Better is 14...Bh4 15.g3 Nxg3 16.hxg3 Bxg3 where Black get two pawns for the knight.
15. Nxc5 Nxc5 16. Bg5 Rd5 17. Be7 Re8 18. c4 :White wins at least
the exchange, so Marco
resigned. ==References==
