More common is 2. Nf3 and then 3. g3.} (2. Nf3) 2... e6 3. Nc3 {Or 3. Nf3,
avoiding the pin.} (3. Nf3) 3... Nf6 4. Nf3 Bb4 5. Bd2 {Ruth: I played this
move to break the pin on the knight. Is this a good idea? Yes.} Bxc3 {Heidi: I
wanted to take the piece that controls e4. I understand, but why the rush?
Black could wait until pressured with a2-a3, and only then--to capture on c3.}
6. Bxc3 c6 {Heidi: I should have folllowed through with my plan of putting my
knight on e4. I agree. After 6. ... Ne4, the game is practicially equal.} (6...
Ne4) 7. e3 d5 {Heidi: I know I'm not supposed to create backward pawns, but I
like this set up. You don't create any backward pawns here, since your e6-pawn
is not on an open file. But 7. ... Ne4 was more useful. In the game, after 7. .

f6-knight out of my kingside.) Anticipating ... a7-a5, I'd play here 13. a4
first.} (13. a4) 13... a5 14. Bc3 {Ruth: I didn't like moving my bishop to a

Heidi: I wanted to ram open her kingside. There lies a problem. I don't know
how to ram open kingsides with pawn storms. Lev: Black's 16. g5 is indeed
interesting--but risky, as it is dangerous (chiefly to Black) to open the game.
After the solid 16. ... Qb8, White's edge is very small.} (16... Qb8) 17. Bd3 {

center!} f4 20. exd5 {Ruth: I considered playing e5 here, to force the knight
back, but decided against it, since my position was so cramped. Heidi: I am
glad Ruth didn't play 20. e5. Lev: Both 20. e5 and 20. exd5 are strong--as
White has an extra pawn!} (20. e5) 20... exd5 21. cxd5 {Lev: This trade allows

into later on. Lev: Not so: 23. Rad1 Ne3 favors Black. Perhaps the subtle 23.
Rac1 is the best, and even a bit in White's favor. But 23. Rfe1, as played,
was also okay.} (23. Rad1 Ne3) (23. Rac1) 23... Ne3 {[#] Too ambitious, as
