Black to play

Black certainly has the better chances in this sharp position but he also has plenty to worry about with his weak pawns and exposed king. The young Ukrainian playing Black found a neat solution to the position.

Solution on June 22, 2014.

You\'re very very close kai2011. At 4...Qd2!, white can play 5.Qg1+, king moves and then 6.Kb1. :)-

I missed 5. Qg1+!! Of course, 4, ,,, Qc2!! Thank You for nice puzzle!-

4Russian  kai20112014-06-16 04:35:37
Oh! After 4. ...Qc2 maximum a draw-

You\'ve almost got the solution kai2011. If you\'ll reflect more on the position, you might see it. I didn\'t even come close to the solution so I can say that you\'re a lot better at this than me. :)-

1...Qa7 2.Qxb3 and 1...Ra1+ 2.Kxa1 Qa7+ 3.Kb1 Qa2+ 4.Kc1 are no good.

2.Bc1

Better than 2...Ra1+ 3.Kxa1 Qxc1+ 4.Qb1 Qxc4, which just leads to a favourable queen ending. The e1-square is perfect for the queen. From there it stops checks on g3, it ties down the white queen to the defence of e4 and, most importantly, it reconnects with the a-file via the a5-square.

3.h4

All other defensive tries fail; e.g.:
1) 3.Qxb3 Qxe4+ 4.Qc2 Ra1+ 5.Kxa1 Qxc2.
2) 3.Qc3 Qxe4+

3...Ra1+!!

5.Kb1 Qa2#.

Of course luring the bishop back to c1 made all the difference.
