Gilmoy: <33.Kb1> Nf2 <shields Black's Q, forks Rh1 and Rc1+ -- White has no time to save everything> 34.Re1 <almost saves everything!>  click for larger viewBlack has at least three plans:
- 34..Qxh1 35.Qxh1 <but see below> Nxh1 36.Rxh1 Rd2, up two pawns and a mobile King. - 34..Rd2 <with the idea Qf5+> 35.Kc1 <whoops ok maybe not> - 34..Qf5+ 35.Ka1 Qc2 (or Rd2)
I think White can always defend b2 in time (with Rb1), so Black has no easy mate hunting sideways. Black can deep-think to find a win by force, else shrug and take the "easy" endgame win ... ... except that it's not quite so easy, since (in the 1st line) White's Q recapture isn't forced. White can return the exchange for a perpetual try, with primitive :) tactical shots: - 34..Qxh1 35.Qxf2!? Rd1+ 36.Kc2[] <36.Rxd1 Qxd1# -- he knows he's offering the R> Rxe1 <so that Black's Q overprotects e4!> 37.Qf5+:  click for larger viewNow it's the Qf5-Qc8 perpetual. Black can return the R to deflect the Q to a worse diagonal: 37..K(g8,h8) 38.Qc8+ Re8!? <he knows he's getting it back> 39.Qxe8+ Kh7 <there is no Qe8-Qe4 perpetual because Black's Q-sees-e4!>  click for larger viewBlack is still two clear pawns up, f7/h2 are only a trade-pair <with check by Black>, and defending h2 allows Qg1 (or Qg2+) and Qg6 consolidating. So this liquidation line actually becomes a Q vs. Q+PP endgame, which might scare off <both> players. Hence Black long-thinks to see if he can do better than that, and White doesn't care for either outcome. |
