Puzzle #214 solution:
Game GM Pia Cramling - IM Irina Krush, WWCh 2012, Khanty-Mansiysk (RUS). This proven to be a complicated puzzle when it came the time to continue the attack (point "c"). One of the reasons was not very good analysis (point "b") for most of the solvers. Analysis should not be like a poem, reciting words and phrases and then nothing; it has to be done with a purpose and the findings to be applied in the solution. Without further ado, here is how the game ended:

`[Event "Puzzle #214"][Date "2013.01.01"][Result "1-0"][SetUp "1"][FEN "k2r1b1r/5p1p/p4p2/2q5/Q2p4/2p1BP2/P5PP/1R2R1K1 b - - 0 22"]22...Qc8 {Solution} (22...dxe3?? 23.Qxa6+ Qa7 24.Qc6+ Qb7 25.Qxb7#) 23.Bf4 Bd6 24.Rb6 Ka7 25.Bxd6 Kxb6 26.Rb1+ Ka7 27.Qxd4+ Ka8 28.Qd5+ Ka7 (28...Qb7 29.Qxb7#) (28...Qc6 29.Qxc6+ Ka7 30.Qb7#) 29.Bc5+ Qxc5+ 30.Qxc5+ Ka8 31.Qc6+ Ka7 32.Qb7#`
