Test your chess: Reitstein problem 188

White to play and win

KV Grivainis v E Turoff 1952

Solution

A better exercise compared with the last couple of days. This is an exercise in calculation, to see whether 1 Qc6! works: which it does. 1…Bc6[] 2 Bc6+[] Kd8[]

3 Be5+ and the queen drops off, with the Ra8 a LPDO: so 3…Kc8 loses simply to 4Bf6, so instead 3…Ke7 when 4 Rd7+ Kf8 5 Bd6+ and mates.
