Last week’s puzzle was taken from my game with Mark Josse (Surbiton) at the end of last season.

I could have scored a totally undeserved draw with 54…Rxb6 55.cxb6 Qb4+ 56.Kd1 Rxc6. Now White might want to prevent Bc2+ by playing 57. Rc1, but after 57.. Rxc1+ 58.Kxc1 Qc3+ 59.Kd1 Bc4 60.Qd2 Bb3+ 61.Ke2 Bc4+ 62.Ke1 Qa1+ 63.Qd1 Qc3+ 64.Qd2 it’s a draw. Or he could press on regardless: 57.a5 Bc2+ 58.Qxc2 (58.Ke2 loses after 58.. Bb3 59.Qb1 Qb5+ 60.Kd2 g3 (to open the 2nd rank) 61.fxg3 Qb4+ 62.Ke2 Rc2+) 58…Rxc2 59.Kxc2 Qc4+ 60.Kb2, which is also a draw.

I was watching a game in the pub the other day, when I noticed this position on the board.

“That’s interesting”, I said. “You’re playing the Englund Gambit. But you’ve forgotten to put the queens on the board.”

“No”, said Bill. “We’ve already traded queens.” “Bill’s just played his fourth move”, added Sue, who had the white pieces. “What do you think I should play next?”

“Never mind that”, I replied. “How did you reach this position?”

Sue and Bill assured me they’d each played four legal moves. But what were they? Can you work it out?
