Subject: Test Position: Strategic

Today Zappa played a very frustrating game against Djinn on ICC.  Zappa had a
practically won position out of the opening (the book said +2-0=1, and Zappa was
evaluating +.5).  Zappa was more or less increasing its spatial advantage when
we came to this position:

[D]1r1r4/ppbbkppQ/2p1pq1p/2PnN3/3P4/P6P/1P1B1PP1/1BR1R1K1 w - - 0 27

First, Zappa has huge branching problems here because of over extending and
changing its mind a lot.  But it seems unable to come up with a winning plan.

1. Rc4 Rh8 2. Qe4 Rbd8 3. Ng4 Qh4 4. Qf3 Kf8 5. Bg6
 = (1.16)       Depth: 9/17     00:00:05.66     1800kN
1. Rc4 Rh8 2. Qe4 Rbd8 3. Ng4 Qh4 4. Qf3 Kf8 5. Bg6
 = (1.16)       Depth: 9/21     00:00:15.49     5073kN
1. Rc4 Rh8 2. Qe4 Ke8 3. Ba2 Rd8 4. Ng4 Qg6 5. Qf3 Kf8
 = (1.00)       Depth: 10/21    00:00:20.85     6809kN
1. Bd3 a6 2. Re2 Nf4 3. Bxf4 Qxf4 4. Rc4 Qf6 5. Ng4 Qg5
 = (1.12)       Depth: 10/23    00:01:18.96     24767kN
1. Bd3 a6 2. Re2 Nf4 3. Bxf4 Qxf4 4. Rc4 Qf6 5. Ng4 Qg5
 = (1.12)       Depth: 10/26    00:01:40.72     31829kN
1. Bd3 Rh8 2. Qe4 Rbd8 3. Nc4 Kf8 4. Nd6 Bc8 5. Qe5 Qxe5 6. dxe5
 = (1.04)       Depth: 11/24    00:02:27.61     46748kN
1. Rc4 Rh8 2. Qe4 Rbd8 3. Ra4 a6 4. Ng4 Qh4 5. Qf3 Kf8 6. Bg6
 = (1.05)       Depth: 11/24    00:02:49.88     53688kN

When I was watching the game, I thought that White should play Rd1, Bc1, Rd3,
and Rf3/g3.  However, when I went back and tried to play as white against Zappa,
I couldn't win.  I'm convinced this position is won for white.  White has a
massive spatial advantage, black is packed on the first rank and has a terrible
bishop.  But I can't seem to win it, and neither can Zappa.

So, can you? :)
