The British Chess Magazine With an extra pawn and a good position Adams is happy to exchange queens here, at least if the circumstances are favourable. 22…d8 23 e1 d6 24 c3 A typical ‘Mickey’ move, not really doing much but just protecting the bishop on d4 and asking Black to come up with a plan. 24…h5 25 g6+ d8 26 ×f5 ×f5 27 g8+ d7 28 g3 c5 29 e3 f6 30 f8 a6?! 31 f7+!

He achieved this easily, forcing a draw on move 14 and thereby finishing half a point ahead with 7/9. Adams performed above 2900, which almost certainly ranks as his best tournament performance, taking his rating to 2761, a career high. 1–0 Sam at the Back Samuel Franklin [email protected] The following game is a demonstration of the combined importance of opening knowledge and calculation. Even at the top level, games are lost very early on due to calculation errors in unfamiliar territory.

For example, he may have assumed that Vallejo had something specific prepared or he may simply have felt more relaxed playing against this arguably less challenging variation. 7 ×c6 is the most popular choice and is a fairly clear-cut attempt at gaining an initiative. 7…×c6 (alternative captures – 7…b×c6 or 7…d×c6 – are less popular and make a6 hard to justify) 8 d3 b5 9 e2 b7 10 d2 followed by long castling gives White an easy-to-play attacking position.
