Malcolm Pein writes on the subject of long-term thinking in his Daily Telegraph chess column today and presents a game with a twin, albeit of the non-identical type.

It is not the first time we have seen creative play by Ian Nepomniachtchi in this column and it certainly won’t be the last.

Malcolm Pein on…Long-Term Thinking

Correctly assessing the worth of long-term compensation for a sacrifice is one of the most difficult things to master in chess. At last December’s Russian championship, Ian Nepomniachtchi played a fine attacking game with a bishop sacrifice for long-term compensation that was extremely well judged.

The game has a twin, as Nepo played a very similar idea in 2008. In both games it is the inability of the defender to develop his queenside that determines the value of the compensation and it proves more than adequate in both games.

22.Rxd6 Qf7 23.h4 Qh7? (23…a5 24.Re3 Ra6 seems to hold after 25.Qf4 Kh7 (25…Rxd6 26.Qxh6+ Qh7 27.Qxf8+) 26.Qf5+ Kh8 27.Qf4 Kh7 =)
