Got really lucky with the 3/5 opening on a Baker board for an early Count
You didn't get lucky with the opening, on a Baker board you will always have the options of opening 3/5 and you played well by opening Count-Silver. Your opponent badly misplayed the opening by spending his coin token and opening Tournament-Silver anyway.
Edit: even if your opponent mis-clicked and accidentally spent the coin token on the first, $3 hand, double-Tournament is preferable to Tournament (spending the coin token)-Silver.
