Your bishop has a really nice view on the b7-square indeed! Especially with all the pawns on the a8-h1 diagonal.  

also, your lovely b file is temporarily closed off

Very cool move!  

Yes...but at the same time the diagonal is being cleared for your bishop attacking the rook on h1.

I usually think of pawn storms as funny ghost threats. your position is completely fine and you have much couterplay in the queenside. As long as you don't give him a target to attack, say moving any of the f,g,h pawns you are fine.

And again clearing the diagonal even more...

Also the text-move enables the d-pawn to go forward.

?? 15.g5 is horrible, but it was lost anyway. 15.Rh3 f6 16.exf6 Nxf6 17.Qe2 gives black an almost winning position.

d4 looks good. ie 15...d4 16.Rg1! Qa5!

I agree..or even 15...Bxc3 wins on the spot.

?? What is the point of this move?...just shifting wood it seems...16...d4! 17.Rh2 dxc3 (not 17...dxe3 18.Qxd7 Bxc3 19.Qxb7)

This was actually to support my knight on d7..as d4 would give me material but white would recapture with Qxd7

the point is to open the b file which he just closed. once again he misses the awesome d4 as sarasani mentioned.

As I mentioned before you panicked and moved a h,g or f pawn. Pawn storms take time and they only work effectively if you feed them a target.

I would not consider this original.

?? This move only makes things worst. 19.f5! looks best here. 19...gxf5 20.g6!

?? The table is turned again: 19...Bxc3 20.Bxc6 Qb6 21.bxc3 Qxc6 and black is obviously better.

? Here 20.f5 looks really good for white. 20...Nf8 fxe6. (20...gxf5? g6!)

I see a few free pawns, I haven't evaluated it properly but I think White's threat is 21.Bxg3 putting more pressure on the h pawn while protected by a mate threat.

well...

Indeed! 21.Bxg6! looks very interesting! 21...Qe7 22.Ne4 hxg6 23.Nd6 wins for white. 21...hxg6 22.f5 Kf7 23.f6 also wins for white. I'd say Wildtbone should have gone for it.

What do you mean irrelevant action. It looks cool there!
