Can't defend against bishop taking F7 pawn first

I have tried and tried to figure this out but I'm stuck. I know how to defend against the 4 move checkmate where the bishop points to the F7 pawn and the Queen is brought out early but what I can't figure out is what to do when the bishop takes F7 and he's unprotected. The next thing that happens is a knight and Queen take over my F7 square and i'm lucky not to be tortured.

What is the proper move when the bishop takes F7? 

Thanks to you both for answers but when I've done that, I've found myself on the receiving end of a beating.

Can you show a specific example?

Yes...here is one that just happened.

Or..the moves were:

Just lost to this s*** in 1 min, no trolling

Here is a quick analysis

Move

2. Play Nf6 blocks checks and developes a pie e the pawn move was bad

4.Stupid develope your pieces

6. Take withepawn pawns are good in the center at the begginnning of the game queens aren't

7. ....

Develope your pie es and follow the simple rules of the opening the attack is premature and weak you should have won

A guy tried the same on me.

See the link below, post 1918, a diagram of the game with computer analysis, then you will find some ideas.

The guy lost the game, despite blunders of both players.

Thanks to those who actually helped...not to those who pulled out the attitude though.

 

This is a real problem for beginners. The game starts with e4-e5, then white B comes out with C4, black responds with Pawn C6 preparing to kick away the B with Pawn d5, but the B does not wait for that and suddenly TAKES THE F7 PAWN! Then the black King takes the B (what else could he do?) but after that immediately comes Qh5, and the massacre begins. The King is very open, cannot castle anymore, and white does what he wants (against beginners). I am still suffering from that, however, sometimes I can defend it e.g. with Kf6 after Qxe5. The key thing is I think that after the white Q gives ckeck, black should not try to defend the e5 Pawn. Black shall block the Qh5 check with g6 Pawn, just letting the Queen to take the e5 Pawn, and then Kf6 can come, and the white Queen is too alone to do something. At this point white will have -3 point in value while black only -2, so no panic.   

If 1.e4 e5 2.Bc4, try 2...Nf6 instead of 2...c6. Then, if 3.Bxf7+, Black can respond with 3...Kxf7, and the N on f6 denies the h5 square to the Q.

You can always play the French defence, then white can't sac the bishop for the f7 pawn as there's a pawn on e6 in the way.

Alternative is the French Sicilian so respond c5 to e4 then play e6 next move, i.e.

Thanks! The main problem is of course that if a beginner is so roughly interrupted in the process of castling, panic starts  . Yes, this French defence variation seems to be effective!

Does somebody know a professional game from TOP 100 in which such sacrifice happened? I could not find such until now; it is extremely rare I suppose. Maybe it is too prideful and improper at that level (and the opponent anyway knows very well how to respond  ) I am interested in the whole game, not only these problematic few moves at the beginning (how the King can be brought into safety, how and when the Queen is involved, how to bring the h8 R into the game etc.)

No. Pro players never would play this
