Advice required

Hey, chessplayers

Just played an interesting game.  At some point I was sure that I am going to win a pice bad just didnt have power to do it. Need your advice regarding middle and end games.

I don't get why you doubled rooks. I thought the idea of your rook lift was Rf3 to win the pinned knight.

In any case, you were lucky at the end: Black missed 49...Qh8-+.

31.f3 was no good idea at all, allowing Black to improve his pawn structure. Just create a passed pawn on the queen side instead.

I like how you handled the opening, surprised at the 1300 rating. 

13.Bd5 is a funny move that works.

As scott said 17.Rf3 nabs the knight.

20.Bb7 then to b6 should win a pawn.

31.a4 is the right idea, trying to get a queenside passed pawn and the black king is far away.  If the black king stays far away then the follow up b4 and c4 should win.  31...axb4? 32.Kd4 with c4-c5-c6 etc wins.

And Scottrf is right.

I like end games, and king and pawn end games are critical to understand. On move 35, did you consider g5 instead of gxh5? When g5 is played, it gives you an advantage, but after gxh5, you neutralized that advantage. The key to the end game position at move 35 is that you have a pawn majority on the queenside, 3 to 2. Knowing this, your advantage will be realized when black is forced to abandon the e pawn to protect against your eventual passed pawn on the queenside (unavoidable with good play). Then you'll be able to run over to his kingside and eat his pawn, and queen there. So I would approach the position at move 35 by first realizing that I can lock up the kingside with g5, forcing a weakness on g6, and then use my pawn majority on the queen side to create a passed pawn, forcing black's king to abandon the E pawn, and once I capture that pawn, I can walk over and capture g6, then promote the g pawn.

Now I didn't play the best moves for black because I wanted to show you the plan in its simplest form, black can try and muddle the queen side pawn movements but eventually with good play you'll create the passed pawn and the plan will go on as I indicated above. End games are fascinating to study!

Let me summarize KingsEye's post, just to have a conclusion to memorize: remote passer in a pawn endgame = huge advantage!

13.Rhe1, instead of Bd3 is pretty good.

16...Rd7 was a big blunder by black (16...Nd7) and Scottrf showed how to punish it.

Wow,thanks a lot for you help. Give me some time to analyze your ideas

Just terribly miscalculated.Was sure that I can both exchange rooks and win the knight.

13.bd5

Dont rly see how it works :/

Right now gonna take advatage of my diamond status  and study some king+pawn endgames. Thanks a lot everyone!

Well, I guess the bishop is invulnerable because Nxd5 would win the piece back up a pawn. But, I see you're threatening the rook, don't know why Ra7 doesn't work.

Am I missing something, or does 12.Ne4 win a piece?

12. Ne4 Nd7

Actually the knight was so pinned there I didn't want a 2 pieces for a rook trade.

Well, 2 B v N+B can sometimes be winning, but even if it is it's certainly not easy. 2 pieces for a rook however, is usually not difficult to convert if your opponent lacks counterplay.

I guess I was in blitz mode and not looking very carefully.  I thought 13.Bd5 Ra7 14.Ne4 Nbd7 15.Bc6 won material but 14...exd5 (although I still like white).

how could black miss 49...Qh8. such an obvious natural move.
