Until 14. ... a6? and 15. ... h6? black was better IMHO.
Simple development vs Benko Gambit
Sort:
FirebrandX - exactly, but 15. Ng5! would still be strong. In Post-analysis she said that she was afraid of one of my pieces tunelling in from b5 but yes - in hindsight g6 is a much better move than the slow moving 14...a6?
Chyss - IMHO the lack of development by black will show itself in a couple of moves. First dealing with the threat of Ng5 would be worrisome eough for black and then she would have to start thinking about getting her pieces out and king safety to say the least! Concrete variations are needed to prove that black can survive... but from my untrained eye it seems unlikely that black can hold of a quick white assault.
I just played developing moves, and she just played too many knight moves neglected opening development!
