drukenknight: it seems that black is trying to hard to hold onto his material gains. Right from the start he is ahead in terms of connected pawns. By the time the 10th moves comes around he has 3 more connected pawns than white, does he intend to convert this advantage into something or does he think he is going to maintain this for the whole game?
The only compensation that white has for the loss of pawns is that black can't castle kingside, perhaps no big deal, but somehow that has to be considered some sort of positional plus.
Okay so I'm thinking black +3 in material. NOw what is wrong w/ 10...Nxf2? a N goes down and breaks up 2 pawns, a difference in material of 1 pt.
BUt what else happens? whites K becomes dislodged, so whatever positional advantage white had in terms of castling has surely been nullified.
SO black could give back a measly 1 pt. in material, still be ahead in material and completely negate the positional problem. In fact he might have an posit. advantage in terms of the King protection for each side:
