White to move — find the best continuation

Solution & explanation

Main line

5. Qb3+ Bb5 6. Qxb5+ Ka7 7. Qb7#

Why it works

  • Great move! queen to b3 keeps the pressure (#2).
  • Well found: queen to b5 (#1).
  • Precise: queen to b7 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Bb5, then Qxb5+ and you win the bishop.
