WINING SPELL

In the second game you posted, you could have played 25.Rxa3+...why wait 3 more moves?
(I think you miswrote and meant how about 25. .. Rxa3+ for black rather than the actual move of 25. .. Nxf1).
- 25. .. Rxa3+ will be a grave mistake for black
because white will answer bxa3 removing the threat on the white king.
so the result is that black sacrificed the a-rook for no-return.
therefore, ideal solution would: simplify the game puzzle, first thing first remove the f-rook and then proceed next!

Bravo! you beat 1300 after he blundered. Strong work.
even that little guy should not stand in your way
I liked the ending game, that is it. not that I am pragging about how mercelessly I beaten him even after blundering or so

I obviously meant Black to play 25...Rxa3+, you were playing Black...
If White plays 26.bxa3, then Black wins the Rook on b1, with26...Rxb1.

there are two things we need to clear differentiate:
1. the actual moves that I have played
2.from the any other suggestable moves
so let me come back to your question: remember 25. .. Rxa3+(your suggestion move) white should answer by 26. bxa3 which is a must as white king can't escape, now that black's a-rook is gone and white has 2 rooks in back rank and it's black turn, black has 2 choices: one to remove the rook on b1_ 26. .. Rxb1 or 26. .. Nxf1 in which black is disadvantaged in either move.
So the actual moves in the puzzle were optimum as below:
24. .. Nxf1 (my actual move since I was playing black)
25. Nxf1(actual move made by white) but best for him was 25. Rxf1
I think it is clearer now friend!

These strike me as being a little long-winded to be puzzles, but that's just my opinion here. The 2nd one seems way too easy to be a puzzle. In the 3rd one, Black loses immediately after 28...bc5? 29.Rh6 but at any rate he's already busted between being 2 pawns down and the precarious position of the unfortunate Kt on h6. If you look at other puzzles for awhile you'll see that in many of them it's the winner who looks busted or who doesn't have an apparently easy way to win.
Don't take any of this personally but I think you should concentrate on using games played vs stronger opponents and start looking at the daily puzzles and other puzzles that arose from games played by masters. You'll improve your own puzzle making abilities by doing so.

here is the complete pgn of that game, check it for yourself

1st game qg3 seems bettter then p. move
but can't move to g3 cause it is occupied by a fellow pawn already in the span of the puzzle. did you mean 27. .. Qg2+? by black
if you read John Nunn's book of end game rooks. first you have to conquer the promising rank. so that is why you have to make maneuvres to achieve full h-file later by delaying the move Qg2+
about the pawn move: it was to deflect the white rook and later expel the queen totally taking control of third rank. Importance being as later seen in the ensueing moving culminating in checkmate.
In this game, I played black and won after white takes the a-pawn and worst of all when he felt victim after outrightly expeling his queen out of the critical third rank! what followed was a dynamo cascade of moves!
