A Chess Player's Best Friend, Part 2: Check Your Discovered Checks!

Last week we discussed one of the most powerful chess weapons: a discovered check. Today you can hone your tactical skills by solving our big test. These puzzles have many different tactical themes, but all of the combinations are based on discovered checks. The good thing about discovered checks is that, once you see a familiar pattern, it is usually easy to find a combo (Of course this is true for many other common tactical themes, like back rank checkmate for example).

Say, you've seen this game before:

Now, how much time will it take to solve the next puzzle? No more than 20 to 30 seconds I guess.

And now, without further ado, here are your test positions:

In the next game 39. Re7!, with a nasty threat 40.Rxg7!, would probably quickly decide the game in White's favor.  Unfortunately, in his usual time trouble, GM Reshevsky played 39.Be5??. The punishment was swift...

Sometimes discovered checks decide the game early in the opening as we could see in the first part of the article, where we analyzed the famous trap in the Petroff Defense. The next two games feature the same Rossolimo variation of the Sicilian Defense and share the same quick result:

Discovered checks happen in the endgames too:

In the next complicated position Black looks OK.  It is difficult to imagine that the game actually ended in a couple of moves!

In the today's final puzzle try to count all the checks White unleashed on his poor opponent!

Not done solving puzzles? Tactics Trainer is waiting!

    While it is difficult to disagree with your point, sometimes I use the ! just to underline the beauty of a move. Therefore a beautiful checkmate in one will get a ! from me even if it is the most obvious move in the position...Smile

    I feel like the ! are too liberally used here...

    A mate in 2 by a GM does not need two exclamation marks.

    @Pastoryoshi: the purpose of Rf1+ is to get the rook protected by the bishop so that after black recapture on b2, white may opt for Bxa6 without being fallen into the skewer ...Rb1+

    in the last puzzle, what value was there in the R checking the K one last time before the B takes the Q; why didn't the B just take the Q right away?

    Nice article with some wonderful examples. Thanks ! Laughing

    Here below is Reti - Tartakower from 1910, a 11 moves discovered check game.

    Perhaps one of the oldest famous examples in chess history, and maybe the first discovered check example I read about as a kid :
