Siegbert Tarrasch - Famous Tarrasch Combinations

Famous Tarrasch Combinations

In the game Tarrasch versus Allies, Black seems to be holding here (at least against immediate catastrophe), because the black queen guards against Qb7+ (followed by Kxa5 Ra1#), while the black rook on c8 defends against Rxc5#. Tarrasch played the ingenious interference move 31.Bc7! (known as a Plachutta interference because the pieces both move orthogonally). This blocks off both defences, and whatever piece captures becomes overloaded. That is, if 31...Rxc7, the rook is overloaded, having to look after both the key squares, since the queen is blocked from b7. So White would play 32.Qb7+ Rxb7, deflecting the rook from defence of c5, allowing 33.Rxc5#. But if Black plays instead 31...Qxc7, the queen blocks off the rook's defence of c5 and becomes overloaded: 32.Rxc5+ Qxc5 deflects the queen from defence of b7, allowing 33.Qb7+ Kxa5 34.Ra1#. Black actually resigned after this move.

In the game against Walbrodt, Tarrasch played rather poorly, and his opponent had the better of it for a long time. But the game is redeemed by the following startling combination:

34.Rxd4 seems obvious, because 34...cxd4 allows 35.Bxd4 winning the queen. But Black has a seemingly strong counterattack which had to be foreseen ... 34...Nxg3 35.Nxg3 Rxg3+ 36.hxg3 Rxg3+ 37.Kf1! Rxd3 and now the startling 38.Rg4!! with devastating threats of 39. Rf8+ mating and Bxe5 not to mention cxd3 to follow. Black resigned.
