The quiz so­lu­tions will ap­pear next week with en­tries open un­til Wed­nes­day. This po­si­tion didn’t make it into the fi­nal cut. If 21 Qh4 Rfd8 the black king es­capes. How can White im­prove on this (solution at the end)?

The first top-class tour­na­ment of the year will get un­der way next week­end in Wijk aan Zee, with round one on Satur­day. As ever, it con­sists of a gra­dated se­ries of events, with the top two, the Masters and Chal­lengers, for­mi­da­ble in dif­fer­ent ways: the Masters sim­ply be­cause it’s so strong; the Chal­lengers be­cause you have to win it to get into next year’s Masters.

That feat was achieved last year by the In­dian grand­mas­ter Vidit Gu­jrathi, who de­spite now be­ing rated 2701 is seeded 13th out of 14 in an event headed by six of the world’s cur­rent top 10: Mag­nus Carlsen (1), Shakhri­yar Mam­e­d­yarov (3), Ding Liren (4), Anish Giri (5), Vladimir Kram­nik (7) and Viswanathan Anand (8). One of Wijk’s charms is that with a field of 14 there is room for some slightly weaker play­ers, which cre­ates a good pro­por­tion of de­ci­sive games. And the bot­tom seed, the young Dutch­man Jor­den Van Foreest, who is rated a “mere” 2614, will have to fight for his life.

This is an ex­tremely busy pe­riod in the chess cal­en­dar, with nu­mer­ous open tour­na­ments in­clud­ing Hast­ings, which re­sulted in a six-way tie for first, in­clud­ing Daniel Gor­mally; the Ril­ton Cup in Stock­holm won by Tamir Na­baty from Is­rael; and a strong tour­na­ment in Burlingame in Cal­i­for­nia near to San Fran­cisco: the Bay Area Open won by Lê Quang Liêm from Viet­nam and Rus­sian An­drey Stukopin.

Opens al­ways throw up some nice minia­tures (games of 25 moves and less) and I en­joyed these, which I picked up from Tues­day’s edi­tion of Mark Crowther’s splen­did weekly digest the Week in Chess (TWIC 1261, see the­week­ Nor­mally it’s the stronger player who pre­vails in minia­tures, but here Amer­i­can grand­mas­ter Daniel Nar­o­dit­sky was put to the sword by a Ven­zue­lan IM. Daniel Nar­o­dit­sky v Felix Yno­josa Bay Area Open 2019 Si­cil­ian 3 Bb5

1 e4 c5 2 Nf3 Nc6 3 Bb5 e6 4 0-0 Nge7 5 d4 5 Re1 a6 6 Bf1 is more com­mon or ear­lier 4 Bxc6 be­fore Black can re­cap­ture with the knight. 5...cxd4 6 Nxd4 Qb6 7 Nxc6 bxc6 8 Be2 Ng6 9 Nc3 Be7 10 Na4 Qc7 11 c4 c5 12

f4 0-0 13 Be3 Bb7 14 Nc3 f5! This nice pawn thrust soft­ens up the long white di­ag­o­nal for the b7 bishop.

15 exf5 If 15 e5 Nh4 16 Rf2 Black is com­fort­able and might af­ter prepa­ra­tion even play for ...g5 later to at­tack on the g file.

15...Nh4! 16 fxe6 16 Rf2 Nxf5 is also bet­ter for Black. 16...Nxg2 17 Nb5 Qb6 Cer­tainly not 17... Qc6? 18 Bf3 and White will win. 18 Bc1 dxe6 19 Bf3 Rad8 20 Qe2 Bxf3 21 Rxf3 Nh4 22 Rh3 Di­a­gram 2

Black has played sim­ply but ex­tremely ef­fec­tively and now in­cluded the queen in the at­tack.

22...e5! 23 Nc3 If 23 fxe5 Qg6+ 24 Rg3 Qe4! 25 Be3 (25 Qxe4 Rd1+ leads to mate) 25… Nf3+ 26 Kh1 Rd2 splat! 23...exf4 24 Nd5 Rxd5 25 cxd5 Qg6+ 26 Kf1 Bf6 27 Bxf4 Bd4 28 Qe6+ Qxe6 29 dxe6 Rxf4+ Here the game fin­ished. This may look pre­ma­ture but Black has a big ma­te­rial ad­van­tage and is win­ning eas­ily. Per­haps White lost on time rather than re­sign­ing?

Di­a­gram 3

22 Rac1 What a pic­ture! Black is paral­ysed while White dou­bles rooks on the c file and then re­moves the c8 bishop so he re­signed.

In di­a­gram 1, af­ter 21 Rh8+ Bxh8 (or 21...Kxh8 22 Qh4+) 22 Qh4 there was no way to pre­vent mate since if 22... Rf8­moves 23 Qh7+ Kf8 24 Qxh8 mate.
