not good for Black to overuse a piece on Queenside without moving something on Kingside. Therefore best to vary with Horse to h6 to g8 also.
fyi....when I thought I was a good player in college, I allowed beginners to play the first 10 moves against me for "free" with idea they could not go beyond the 5th rank and I was allowed to recapture pieces during those 10 moves. Same affect as this opening.
If you wish to try this out on me, feel free to challenge me. I am past my prime.....
Snail opening. Made up by me.
