It’s Your Move: daily chess puzzle #262

White to play and win

Dueball-Burnett, Berlin 1970

Solution

The first moves are fairly simple, and White has the big practical luxury of a fall back perpetual check, if nothing else.

1 Nf7! Kf7 2 Qf6+ Kg8

And now the main task is to see how to rook lift or get the B in. 3 Ra3! seems natural, and indeed wins after 1…Na3 2 Qg6+ Kf8[] 3 Ba3+ when 3…Qc5 is forced. Or, 3…f4 when after 4 Bf4 Ra3 5 Re3! the other rook swings over to g3, 1-0.
