I ran into this position during play with computer, but I'm not sure if its winnable (I'm, White). Also, any comments on my play/computer's play would be highly appreciated.

I'm not sure how to use this site's chess diagrams, so I'll just post the PGN file here:

I'm not sure how to use this site's chess diagrams

First off, to learn how to make chess diagrams here read carefully answers to this post.

As for your question, I will give you brief comments about the game first, and then analyze the endgame.

Also, any comments on my play/computer's play would be highly appreciated.

Since SO hasn't added written commentaries to follow a move, I will refer to the move, and then comments will follow.

If you have further questions leave a comment.

Best regards.

Let us start:

Your opening play was not precise, but you still had a playable position until 15.e4. After that move Black had a small advantage and an initiative. I do not play 1.e4, nor do I play the French defense. Even if I did, I would advise you to prepare your openings well by consulting an opening book. That should remedy the mistakes you made in your game.

Although Black was better, you still could count on a draw. 21.a3 seems desperate-it looks like you had no idea what to do, and it is a pointless move. You have no advantage at the queenside so there is no reason to start action there. This would also be slow plan and would weaken you more than helping you. At this moment it was crucial to somehow break the pin. One idea would be Rd1 after b4-something like this:

[White "namehere"]
[Black "Computer player"]
[fen "4r1k1/pp2q1pp/2pb4/3p4/4P3/2P2QP1/PP4BP/4R1K1 w - - 0 1"]

1.b4 a6 2.Rd1! dxe4 3.Qxe4! Qxe4 4.Bxe4 Rxe4 5.Rxd6

with some chances to draw.

At move 23. you had a chance to execute my combination and get back into the game. At the end of the combination the opponent's king would be threatened by mate, so you could get a slight advantage there. After missing this chance, you had to struggle for a draw-I would try to reorganize my pieces like this:

[Title "Suggestion for piece placement"]
[fen "4r1k1/pp2q1pp/2pb4/3p4/4P3/2P2BP1/PP2R1KP/4Q3 w - - 0 1"]

so I can achieve exd5 and equalize.

The rest of the game the computer played pathetically and squandered the advantage.

Is this endgame winnable(for White)?

As for the endgame, it is a draw-Black plays Bf4 and enforces blockade on the dark squares after which White has nothing. It will look something like this:

[Title "Endgame analysis"]
[fen "8/6p1/1p3k2/1P2bP2/6PK/3p1B2/8/8 w - - 0 1"]

1.Be4 d2 2.g5+ Ke7 3.Bc2 Bf4 4.Kh5 Kf8 5.Kg6 Be5 6.f6 gxf6 7.gxf6 Bd4 8.f7 Bc3=

Thanks a lot for the comments, it's really helpful. The reasons why I love SE! –  namehere Feb 27 at 14:37
    
I'm not sure why black would play a6 in response to b4. Also, could I have some more advice on how to play a good opening? –  namehere Feb 27 at 14:43
    
@namehere: a6 is weak, but was "played" just so I can show you how to perform a combination. The true chance to play Rd1! came later, as I have pointed out. As for openings, I need more information to help you. A separate question could help me-especially if you provide more specific details of what you need help with. Best regards. –  AlwaysLearningNewStuff Feb 27 at 14:53

Obviously, white can't win. Let white do any move except g5+ (Kh5, for example) 65... g5 66. fxg6 Kg7 Now black bishop will move on squares c5 and g1 and white can't do any progress because pawns are blocked.

Moreover, I like black's position more,

May I also receive some advice on my play? Thanks. –  namehere Feb 27 at 11:29
