[Not feeling like there was any particularly good move at the moment, knowing pressure will be in the center and not wanting to risk a back rank mate, seemed appropriate to create space for K or escape for N. DA] [ 19.Nd2

[Now thinking that Qh5 could become a nice threat. Thought maybe Bf7 could be better but leaving R on e1 could become an issue with Qxe1. Also, not liking Rc8 response. Also thinking Bd3 slows advance of pawns. DA] 22...Nd5

should be considered] 23.Be4+/-
[Not wanting to allow Nf4 and pinning N to B while contesting the diagonal. I&aposm happy. DA] 23...Rad8

not a good decision, because now the opponent is right back in the game [Thinking Nd6 will be perfect. DA] [ >=24.c6

A double attack [What???!!! Sigh. What a mess! Am I dead? Let&aposs see. Sigh. fxe3, dxe3, Q where? And down goes B on e4 with pin on R and N. Also, Q is the only thing holding R on e1. Sigh. Nxe3 and I have similar issues with pressure on f2. Sigh. Well, the R might as well take the N and give the Q some room to move. DA] 25.Rxe3

Threatening mate: Qxg7 [Maybe I can get a draw....hmmm/\.a mate in 1 threat. Well, saves the B....maybe this is okay after all....maybe I win the B on b7. DA] 26...exf2+
