Double check is only possible by using discovered check. So either the rook check or the bishop check was discovered by moving something in between on the previous move.
I don't see how that's possible with the rook check, but it is possible with the bishop -- if the board is shown with black at the bottom, contrary to what is usually done. Then there could ...
It is not checkmate because Black can interpose a piece to block the check from the bishop: move knight or queen to e6.
It's still only a miniscule delay for the inevitable.

Can we do better ?

If this is best, interestingly, the play is almost forced. The only variations are 4...Kd6 or 4...Ke7 in the line above, or 4...Ke6 and 5...Kf5, or 3.Kf1 Kd6/Ke8 4.Bxd7 Kxd7 5.Kg2 Ke6 etc. Only five possible ...
There are probably as many quick mates as there have been first time players (since we all get caught in these at the start!) but here are a few common ones:
This is the shortest possible checkmate in a mere two moves:
1. f4 e5 2. g4 Qh4# 0-1
White can also play f3 instead of f4 or move the g pawn before the f pawn.
It's impossible to checkmate faster than 7 turns (handicap on black) or 8 turns (handicap on white).
Proof by elimination
I'm going to argue from the perspective that white is helping and black is handicapped, since otherwise it would take 1 more move.
Only Queen, Bishops and Rooks can be used by the black player to threaten the white king, as only they ...
If you drive an enemy king into a corner, you still need to control four different squares to checkmate him. Your king can control two of those squares (but cannot approach the enemy king), your knight can control the third, but there is no way of controlling the fourth. That is, it is impossible for the knight to control both the corner square and the one ...
For a short mating possibility in a very standard mainline opening, one can look to the Smyslov-Karpov variation in the Caro-Kann Defense:
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Qe2 Ngf6?? 6.Nd6#
The most popular continuations are 5. Nf3, 5. Bc4 and 5. Ng5 (an aggressive try which Kasparov assayed a number of times against Karpov). ...
I know you're a FIDE Master :), so I suppose you're more interested in this question from a teaching perspective.
The simplest way to understand a checkmate with King and Rook vs King is the idea of the rectangle of the opposing king. Consider this position-
Here, the Black King is restricted by the White Rook in this giant rectangular area of the ...
It is not checkmate if the other player has any legal move that gets them out of check. Capturing the checking piece is one such way; whether the capture is en passant or not is irrelevant for the purpose of this question.
In this case, an en passant capture is the only legal move. If the other player didn't know the en passant rule, I suppose they might ...
The position shown in board 2 is not a checkmate, as you correctly say.
The book is not completely clear here. The sentence "Checkmate with Queen and King" is only the task of an exercise: you have to set up the position you see on a real board, and move the pieces trying to checkmate the black king using the white Queen and King. The checkmate is not ...
This is really a question for fairly low-rated players, who tend to play things out to the bitter end. If you are reasonably strong, the only reason your opponent does not resign earlier is that he thought you played such a good game that he allows you to execute the checkmate (I have done this), or thinks that the final position is beautiful, and saw it ...
Actually, the bishop and knight mate is not as slippery as it appears. I have checked this on a tablebase program I wrote. On a 10x10 board, the side with the bishop and knight (say white) can force mate in at most 47 moves. White can even force mate on a 16x16 board, in at most 93 moves. I believe mate can be forced on an arbitrarily large even size ...
I can think of two questions you might be meaning to ask, given the wording of your question. Maybe neither of these is what you're after, but just in case:
1. Is it possible to castle out of check or even checkmate? Here the answer is no. If your king is in check, then castling is not a legal move.
2. Is it possible to castle while checkmating your ...
Most basic first - this rule is the reason that King vs King is an immediate draw. Neither side has a piece to check with, let alone checkmate with. A position that is a draw because neither side can win is called a "dead position".
Playing against a bare king, a bishop or a knight is insufficient to checkmate with, and therefore K+B v K and K+N v K is ...
Imagine a variation of chess without the rules about check and checkmate, where a player wins simply when he captures his opponent's king. In this variation, Kxd5 loses the game to exd5.
Turns out, that's more or less how real chess works. The objective is to capture the opponent's king. If your king is under attack, you must deal with that threat. If there'...

In a tournament game, you are not supposed to speak at all other than to offer a draw or adjust a piece. This includes saying check. This tends to seep into casual games among more experienced players (I haven't said check in years).
For players that do not compete in tournaments at all, I don't think that there is any obligation to point it out.

105 mates — Nenad Petrovic, Sahovski Vjesnika 1947 (Chess Problem Database)
In this position any check is mate. There are 3 knight mates (c4, g4, f7), 23 discovered mates (14 moves for the rook on c7, 9 for the bishop on b5), and 79 queen mates: 1 on a1, 2 on b2, 3 on c3, 4 on c5, 6 on d4, 3 on ...
I always like to explain this in a visual way.
Basic Idea: Keep the bishops together. They form a large net (restricted area) from which the opponent king cannot escape.
Step 1: Push Opponent's King To Edge Rank or File
Keeping the bishops together and using the king for support, make the restricted area smaller to push the opponent's king back to an ...
No. The touch-move rule can't force you to make an illegal move, and it is not legal to put yourself in check.
Here's what the FIDE laws of chess say:

Article 4.4 can be moved or captured, the player may make any legal
Is it really possible to checkmate with two knights and king against a
Theoretically, the checkmate is possible, but you can not do it in practice unless the weaker side allows you to. This is related to a drawback in the way knight moves.
There is a mating position with this but no extra tempo to do it in
What are the ...
Double check is a fine tactic. An example would be a bishop lined up on the same diagonal as the king with a rook or knight in the way blocking the check. The rook or knight moves giving check to the king and also uncovering the check from the bishop. The king must move since there is no way to block two different lines or take two different pieces at the ...
You can find some examples in the following game collection: Games where check is answered with checkmate.
Among those games, Nigel Short vs Alexander Morozevich, Russia - The Rest of the World (2002) is the only one that meets the qualification top players. This was a rapid game.
The most entertaining example is the following:
