The following position was reached yesterday (White, Franceys Allen, to play) against David Green in the third round of the Stowmarket Club Championship:
Franceys, who was short on time with about four minutes remaining, played Qxh7??
I’m sure you can work out how David can force a win, but in case you’re struggling, the answer is lower down this page.
…f4+! 0 – 1
If Kxf4, then … Qe5+, Kg4 Qf5#
If Kg4, then … Qf5#
If Kh6, then … Qh5+, Kg7 and after the exchange of queens, Black’s g-pawn will promote.
