Who can see this?

A couple days ago I lost a game on time.  I missed two forced mates along the way.  I was rated 1238 for blitz at the time and am now 1305--I move around a bit.

What I'm curious about is who "should" see these with a high degree of certainty?  A 1400?  1600?  1800?  I suppose I'm talking about chess.com blitz ratings here.

Here I miss 24.Qg8+ Rxg8, 25.hxg8Q+ Rxg8, 26.Rxh6#

And here I miss 26.Qg8+ Rxg8, 27.hxg8Q#

I really don't think I'd be too likely to see the first one.  The second one I'd like to think I would, but clearly I didn't.

What do you think?

JMO, but i think anyone that is decent at tactics can see these mates.  They are both easy forcing lines.  You did mention blitz, so i am assuming this was a blitz game?  If so did you miss it due to being low on time?  Moving to fast?  Would this be a mate you would see at a longer time control?

Yes, it was blitz (G10), but honestly, I can barely see the first one even knowing it's there.

The second one is easier but the fact it relies on a sacrifice, a file clearance, and a double check, all in three ply...I'm not sure I'd see it either...even with a fair amount of time.

Neither of us play blitz on chess.com so we won't have very good opinions :p

Remove the knight, and now do you see it?

Yeah, I was going to ask something similar.

Is it easier to visualize the line Qg8 Nxg8 hxg8=Q mate?

The reason i brought up removing the knight is because the first position reminded me of a position i read about years ago.  It had something to do with tactics, and a piece that seemed "misplaced"

Basically our brains dont want to see what we should see.

That is easier.  I think the problem is, for whatever reason, I have a strong tendency to want to recapture with the rook on g1 rather than the pawn on h7...not sure why.

They are intuitive and seem basic to be honest. It takes me some seconds to figure out with certainty the outcome though. That's unfortunate with tighter time controls.
