How to keep your cool after a blunder - move by move analysis
Thinking (?): What is White's best practical chance after this blunder?
In conclusion:
Even though White lost a pawn early in the opening, from then on out it looked as though only White was calling the shots. This was because of Black's inaccuracy (...Bxa3).
The lesson to learn here is: Don't give up after blundering a pawn: look for your best practical chance: be a ferocious attacking beast!
Best,
