Discoveries Tutorial



1.
[{F:W}{B:64 WHITE}{D:6000}A Discovery is an attack that's Discovered when an intermediate piece moves out of the way. {B:3q4/24/3N4/16/3R4 WHITE}{D:1600}{A:Wd4b5}{D:1000}{R}On this set-up, if the Knight moves away{S:d4b5}, the White Rook{D:1000}{A:Wd1d8}{D:7250}{R}{A:Bd8d1}{D:2000}{R} is now attacking the Black Queen. This is a Discovered Attack. Unfortunately, the Black Queen is also attacking the White Rook, and it's Black's turn, so this is not really an effective Discovery.{W:DSL_001}]

2.
[{B:3q4/8/7k/8/3N4/16/3R4 WHITE}{D:6000}Here's the same set-up, but with the Black King added on h6. Now, if White moves his Knight to {S:d4f5}{D:3000}f5, he's {A:Wd1d8}{A:Wf5h6}{D:2000}{R}{D:1000}attacking two pieces at once. Black must save his King{S:h6h7}{D:2000}, so White wins the Queen.{S:d1d8}{W:DSL_002}]

3.
[{B:8/7q/3r4/8/3pP3/3B4/2P5/8 WHITE}{D:5000}Here's an example of a Discovery involving a Pawn. When the Pawn moves to {S:e4e5}{D:2000}e5, the Bishop's {A:Wd3h7}{D:3250}attack on the Queen is revealed. Black saves his Queen{R}{S:h7d7}{D:1700}, but loses his Rook{A:We5d6}{D:1000}{R}{S:e5d6}.{W:DSL_003}]

4.
[{B:6k1/5ppp/16/3B4/7r/6R1/5B2 WHITE}{D:5000}On this diagram, White's most obvious Discovery occurs by moving the Rook to {S:g2g7}{D:2800}g7. The King must move away, {S:g8f8}{D:1600}and White wins{A:Wf1h3}{D:2000}{R} the Rook. However, there's another move for White. Can you find it?{W:DSL_004}]

5.
[{B:6k1/5ppp/16/3B4/7r/6R1/5B2 WHITE}{D:1500}Look what happens if you move the Rook to {S:g2e2}{D:3000}e2. Now, the Bishop {A:Wf1h3}{D:2800}is attacking the Black Rook, and the White Rook {A:We2e8}{D:4500}is attacking the e8 square. Black must act to save his King{R}{S:h7h6}{D:2000}{A:Wf1h3}{D:1000}{R}, and White wins the Black Rook{S:f1h3}.{W:DSL_005}]

6.
[{B:r5k1/7p/5ppB/2b5/2N5/7P/Q4PP1/5RK1 WHITE}{D:4000}Here's another example of a Discovered Attack. White moves his Knight to b6{S:c4b6}{D:1500}{A:Wb6a8}{D:2000}{R}{D:1500}, attacking Black's Rook. This move reveals a Discovered Check{A:Wa2g8}{D:2000}{R}{D:1700} on Black's King. Black must move the King{S:g8h8}{D:2000}, and White wins the Rook{S:b6a8}.{W:DSL_006}]
