I was idly watching the games from the Tata Steel Challengers the other day when I noticed that the game L’Ami – Beerdsen, which had been winning for Black, was now equal.

In this position Black continued Qh2+, a few moves later sacrificing for a familiar perpetual check.

But he had a win here:

41… Bd6 42. Qxd6 Qh2+ 43. Rg2 Rxf3+ 44. Nxf3 Qxd6 45. Rxg7+ Kf8 with a winning material advantage, although I suppose there might be some technical difficulties to be overcome.

You can see the game here.

Did you rise to the challenge by finding the win Thomas Beerdsen missed in this position?

The Masters and Challengers sections are both building up to an exciting climax, with the final rounds this weekend. I’m sure you’ll be watching them – and perhaps learning as well.
