can people still post puzzles here for submission?

It says this forum is closed to submissions......

aww I had a boss problem to submit!!

you can still post it here for everyone to see, even if it doesn't get submitted

that's weird, I've already posted the game in another forum.

Luckily, my opponent missed this in a recent game. 

He played 2... Nd5+, and I lived to fight on!

(yes, white could throw his rooks away to add a few more moves, but it doesn't change the outcome.) 

If a puzzle is really good it will still be added. ;)

After Rh2+, blacks best is Kg1. However, the puzzle must end after Rh2+.

If you mean White playing Kg1, it can drag out longer, but it's still forced. 

2. Kg1 Rg2+ 3. Kh1 Rxg4+ 4. Kh2 Rg2+ 5. Kh1 Ne2!  That threatens both ...Ng3# and Rh4#; White can't stop both.  I'll add this line to the diagram above.

The puzzle would not have to end after Rh2+; the computer (white) could make any of the four legal moves and the human could still force a mate. 

It depends on who's approving the puzzle. If it were me I'd have to have a closer look as there are a few lines that have significant advantages for black without mate. Overall, however, a very neat combination. Well spotted :)

Thanks, I wish I'd spotted it a little sooner.  :(  After I eventually lost, the chess.com computer analysis also concluded it was a forced mate in 8 after my blunder 1. Kf2.

he said it was closed.

EndgameStudent, here is my puzzle. I took this from puzzle book of Blokh named "Combination art". this must be very interesting. Here's solution: 1...Rh2!!! 2. Rxh2 2...Qxa3!! 3. ba 3...Bxa3 4. Kb1 4...Nc3 5. Ka1 5...Bb2! 6. Kb2 6...Nxd1 7. Kc1 7...Nxe3. That's Brilliant. I guess you'll post my puzzle. Bye.

EndgameStudent, did you post my puzzle??
