Could you do a small test analysis for us? Something not too difficult like analyze this position to mate:
[d]2b3k1/r2r2p1/p1N1q3/1B6/3p4/2b1B2R/PPP5/2K4R w - - 0 36
No outside help please!

Before I forget, the origin of the position in the test was from my analysis of the game Tal-Koblenc 1957
[pgn]
[Event "?"]
[Site "?"]
[Date "1957.??.??"]
[EventDate "?"]
[Round "?"]
[Result "1-0"]
[White "Mikhail Tal"]
[Black "Alexander Koblenc"]
[ECO "B63"]

Qxc6 36.Rf6+ Rf7 37.Qxg7+ 1-0
[/pgn]
After 31... Rd7
[d]2b2knQ/r1qr2pR/p1N1p3/1B3p2/3p2P1/2b1B3/PPP5/2K4R w - - 2 32
The best line of play appears to be:
Code: Select all
( [Stockfish 030520 64 POPCNT] 74:M29 32.g5 Qg3 33.g6 Qxe3+ 34.Kb1 Qe1+ 35.Rxe1 Bxe1 36.Nxa7 axb5 37.Nxc8 d3 38.cxd3 Bd2 39.Nd6 Bh6 40.Ne8 Kxe8 41.Qxg8+ Ke7 42.Rxg7+ Bxg7 43.Qxg7+ Kd6 44.Qf8+ Ke5 45.g7 Rxg7 46.Qxg7+ Kd6 47.Qb7 Kc5 48.Qe7+ Kd5 49.Qd7+ Ke5 50.Qxb5+ Kf6 51.a4 f4 52.a5 f3 53.Qc5 f2 54.Qxf2+ Ke7 55.a6 e5 56.a7 e4 57.a8=Q e3 58.Qxe3+ Kd6 59.Qd8+ Kc6 60.Qeb6# )
But this is way too easy to find. The second best move, 32.gxf5, leads to the test position after 32... Qg3 33.R7h3 Qd6 34.Qxg8+ Kxg8 35.fxe6 Qxe6
we now have this:
[d]2b3k1/r2r2p1/p1N1q3/1B6/3p4/2b1B2R/PPP5/2K4R w - - 0 36
