As usual my curiosity for Knight openings and defenses sent me to the little gem 1. c4 Nh6? . I believe they refer to a Knight on the rim in the opening to be a Drunken Knight. A past UON stirred the interest of this opening for me. What's interesting is yes the Knight is on a typically bad square, yes it will be threatened with capture from the c1 Bishop, and yes it will have to move before or at the beginning of the middlegame. These are all usually bad things, right? For below 2000 ranked players, I don't think so. In fact I think this Knight offers some very interesting ideas.
1. With a Knight on h6 it can ,at some point in the game, post out to f5. Penetrating deep into the enemy center, attacking e3 and d4. I like how in hypermodern openings the Knights attack the center with out actually occupying it. What's interesting to me, is that a Knight at f5 does the same thing but penetrates deeper. Maybe not sound for the opening but may make for interesting play in the middlegame.
2. With the push of the pawn from f7 to f6, a nice little nook can be made for the Knight at h6. From here it influences a good section of the center, doesn't allow a capture or trade of the Knight and keeps it more toward the 'action'. This has been played many times before and usually follows the kingside fianchetto. Although the pawn blocks the Bishop at g7, with the right tactics many possibilities can occur. Discovered attacks with the Bishop maybe?
3. After 1... Nh6 2... g7, the Knight is protected by the Bishop at f8. So if there is a trade with the Bishop at c1 then there is no loss. You gain the Bishop pair, develope a piece, and attack a central diagonal. Sounds ok to me.
With the knowledge of these positions I will test it out at chess.com in their live room. I don't encounter c4 that much in the opening so I'm going to run another engine tournament tonight with 1.e4 2. Nh6. They'll be 1 min games since I'm interested in the openings and how the final games look as the engines do their 'book learning'. Maybe do a 1.d4 tournament tomorrow.
The tournament I ran over the weekend saw 288 5 min games by three engines in a round robin tournament. The PGN for all 288 games can be found here: http://www.lockism.com/engine/c4Nh6.pgn . The results looks as such:
