In the first game I think that 5. axb5 axb5 6. Qf3 is more accurate
If you accept the Queen's gambit, don't defend that pawn
the first game on turn 5 white should capture the b5 pawn with his a4 pawn and when black recaptures with his c6 pawn white should then move his queen to f3. the only way black can save his rook is by sacrficing his knight. if white plays correctly black will NOT be able to trap the queen if the rook is sacrficed instead
Also, your last game isn't even a variation. It is idiocy played on both sides.
That's why it's called the Super Fail variation
Huh... why not 5.ab5 instead of 5.Nc3? Black loses a piece if he takes on b5.
After 5.Nc3 (quite certainly not best here) Black should play 5...b4 with a fairly respectable position - it has been played even at top level, although (of course) under a different move order.
can u explain sir? i didnt understand... did you mean 5 axb5??? and how does black loses a piece if he takes on b5???
Because after 5)axb5, cxb5; 6) Qf3! black has to either lose a rook, or lose a bishop by playing 6)Bb7; 7) Qxb7, Nd7
This is a line where black at least initially holds on to the pawn. Of course with accurate play white will always get it back, but it doesn't have to be disastrous for black:
GM Ftacnik compares this to the Noteboom variation in the Semi Slav
Or this failed variation.
Or this very fail variation.
