I think this was one of my better finishes. Overall, what do you guys think of this game? I know that there must have been some serious blunders, I just can't see them. Would appreciate any thoughts, on the ending especially (I think black just gave up).

nice game! I think you're right! He shouldn't have let you take the queen!

2. Na3. Why does the knight go to the side of the board? Knights are not very useful on the side of the board.

3. c3 What is the objective of this move? It doesn't increase the potential of any of your pieces. In fact, it decreases the potential of your bishop, which could have gone to b2, but will now be blocked in there.

6. h3. Way too many pawn moves without doing anything to get your pieces going. You are lucky black didn't take advantage of you. And this move in particular accomplishes nothing. It doesn't fight for any important territory.

The rest of the game is a comedy of hanging material. How can you say you don't see any blunders?

What is the opening called?

It does appear that white is attempting to utilise the ROT system, doesn't it? A general comment for your opening play would be to play more towards the centre (e.g. c4, d4, e4 as first moves) and develop more PIECES rather than pushing PAWNS. If your opponent were any better, they would have gained a massive lead in tempi and would have more than equalised- as it was, you were lucky.

No, Nytik, it appear white is employing no system whatsoever.

Black's opening mistake is 5. ... e4. A lead in development is not as valuable with a closed center. So instead of closing the center, black should continue to build his development lead with 5. ... Nc6 or 5. ... Bd6. Black wants to keep the central pawn tension so that the center can be opened with pawn exchanges. If white initiates the exchange, this does not hurt black as he will recapture bringing a piece into the center. Since black will be able to castle first, it's possible a direct assault on white's uncastled king once the center opens will be decisive.

It is called the Polish opening.

Also, I thought I saw blunders but was not sure.

That is why I said ATTEMPTING.  As the ROT system would do this a lot more effectively than is shown here. Also, I said APPEARS TO BE. Subtle language, effendi.
