RT — I don't really understand what your aim was with any of your moves 19–23. Is that the part that you're referencing where you didn't really have a plan? None of the moves seem to generate any sort of counterplay and I can't see how they set up future counterplay.
The biggest problem I'd have with your position at around move 18 is that while black seems to have space, there seems to be almost no counterplay and the only pawn break available is ...f5 which looks pretty tough to set up. I would probably try to either organize that sort of thing or really try to solidify my kingside. Or perhaps try to wrest control of c4 away, since I guess there could be a future pawn breka there, but that seems like a pipe dream since white has full control over it and I don't really see how black even goes about getting control of it. I guess you could try to pin his pieces down by threatening ...c4 in some manner as counterplay.
I have no real concrete variations to offer though so I'm sure Rei will consider this post a bunch of gibbering garbage
(j/k...although, yeah, not sure it's a very helpful post).
