after falling for this trap for the 50th time, screaming "HOW DO I EVEN STOP IT?!?!"
Note that your king defends f7, so there isn't actually a threat there. Therefore, simply defend the threat on the pawn. If you see that your pawn keeps getting captured, simply defend it the next time you come into this situation. Try Nc6.
thx for advic
is stupid enough to fail like this
