Opposite sides attacks are a clear indication both players want to win. Of course whoever's attack is faster, will get the best shot at winning. Here is the game played so far:
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Be2 Nxd4 7.Qxd4 g6 8.g4 Bg7 9.g5 Nh5 10.Qe3 O-O 11.Bd2 Be6 12.O-O-O Rc8 13.f4 d5 14.exd5 Bxd5 15.Nxd5 Qxd5 16.Kb1 Qc6 17.c3 b5 18.f5 b4 19.c4 a5 20.Bc1 a4 21.Bxh5 gxh5 22.Qxe7 Rfe8 23.Qxb4 Qe4+ 24.Ka1 Rxc4 25.Qb5 Rec8 26.f6 Bf8 27.Rhe1 Bb4 28.Rf1 Qe2 29.Qb7 ... see diagram. Your tasks:
a) Name the opening;
b) Analyse the position for both sides and decide on the best plans for both;
c) Black to move and win; choose the best continuation between the following 3 choices:
(I) 29... Qxd1 as Black can take advantage of the back rank weakness;
(II) 29... R4c7 chasing the Queen away first into a bad position and then execute the continuation from (I)
(III) Don't like either choices and will play mine.
In all 3 cases, please show a few moves to prove your choice.

Puzzle #215 solution:
GM Sveshnikov - GM Fridman (rapid game), Tallin, Paul Keres Memorial 2013. The answers were better this time, with a few clarifications needed and done in class. Here are a few:
- White has not castled yet; however nobody is attacking the White King.
- Black has castled the long way, giving up tempi used by White to develop more pieces.
- The entire Queen side for Black is undeveloped.
- The Black King is not protected very well.
- White dominates the center.
- "Bc1" even if not moved yet, is an active piece. A complete solution looks like the one put together by GM Spraggett:
If 13... gxh6 14.Qg6 ... 1-0
If 13... Rxf3!? 14.Bxg7+ Kxg7 (14... Kg8 15.gxf3 ... 1-0) 15.Qg4+ Kh6 (15... Kf7? 16.Qxf3+ Ke8 17.Qh5+ ... 1-0) 16.gxf3 d6 17.Qf4+ Qg5 18.Qxg5+ Kxg5 19.Nxc7 ... 1-0]
14.Bg5 Qe8 15.Qh4+ Kg8 16.Ne7+ Kf7 17.Qh5+ ...
[GM Spraggett analysis: White missed a mate in 3 here with 17.Qc4+ Be6 (17... d5 18.e6+ Bxe6 19.Ne5#) 18.Qf4+ Bf5 19.Qxf5#]
17... Ke6 18.Qg4+ Kf7 19.e6+ 1-0"
