Nb3 for me too. Resign and Start over will even be better.
i like f3
f3 loses immediately
30.f3 Qd4+
31.Kh1 Nxa1. We are down a rook, our king is open and our bishop on d2 is still be pinned.
30.f3 Qd4+
31.Kf1 or (Ke2) Ne3+ winning our queen
30.f3 Qd4+
31.Kh2 Qf2+
32.Kh1 Rxd2 (we will lose our queen to delay checkmate)

Nb3 looks good, supporting the bishop as well

I agree for the reasons above. We are losing but Foxpup is right that we would lose much faster if we move our rook and allow Nd4.

Your move bitcointalk. You have the white pieces
The current position is updated below:
29.cxb5 Nc2
Good job solving the first study by Richard Réti. Several of you seem to have solved the second problem (based on your comments and hints) by Rev. Fernando Saavedra but since I do not see the solution posted yet I will let the rest of you solve it before posting another problem.
Remember the concepts from the first problem. They will save you calculation time in king and pawn endgames.
The second problem looks easier than the first one to me. Just play c7 and black cant stop you from queening. Black can give some checks, Rd6 check, Kb5, Rd5 check, Kb4, Rd4 check, Kb3, Rd3 check Kc2 and queen next move.
The hard part was seeing Rd6 check, Kc5 is a mistake because of Rd1 and c8=queen loses to Rc1 check. White can still make a draw with Kc6 or Kb6 instead of c8 = queen
The hard part was seeing Rd6 check, Kc5 is a mistake because of Rd1 and c8=queen loses to Rc1 check. White can still make a draw with Kc6 or Kb6 instead of c8 = queen
The second problem looks easier to you because you think you solved it! You have not completed the problem.
"Kc2 and queen next move" is not correct with best play by black. Try to figure out why. After you play Kc2, black will play Rd4. Spend more time thinking about what will happen next.
The first problem touches on one of the most important ideas in king and pawn endgames (along with opposition) the square of the pawn.
Are you saying that I should be solving all the way to mate? I know that King and Queen against King and Rook is supposed to be enough to win. Eventually the person with the Queen can either win the rook or force checkmate.
Read the clue I gave you again. If I say more I will give it away. Look at the position after Kc2 and Rd4.
Ok. I added a few more moves to the end to complete my answer.
Just play c7 and black cant stop you from queening. Black can give some checks, Rd6 check, Kb5, Rd5 check, Kb4, Rd4 check, Kb3, Rd3 check Kc2 and queen next move.
Based on your comment of Kc2 Rd4 from my solution above I add a few more moves: c8 = queen, Ra4 (to stop Qa8 checkmate) then Kb3 threatening Kxa4 and Qc1 checkmate. Black can't save both the rook and checkmate.
You are missing the most important part of the problem. Black has a better move than Ra4 after your c8(Q) move.

King vs King: impossibility of checkmate
you will have to move your king in the diagonal. So Kg7,Kf6.
Why? I have to prevent the black pawn to reach h1. And my pawn is condemned (he cannot escape from the black King).
just try it. you can't stop his pawn so you have to get closer. to your own pawn. if he walks with Gus pawn walk to your pawn and promote. If you goes for your pawn you get in the square of his pawn to capture it

You're welcome. This are great ending studies. I got also a few nice ones in some books. Gotta search for them.

I found the solutions to both puzzles but the harder one was actually easier for me lol, I saw the plan as soon as I looked at the position. The easier one on the other hand had me scratching my head for a minute there 
I know why though, it's because when you look at the white pieces separately, it just looks impossible, the white king can never catch up with black pawn and the white pawn can never queen

I've had time to look at the position some more and I have revised my assessment. After cxb5, Nc2 is a lot stronger than Bg5 for black.
29. cxb5 Nc2 30. Ra2 Bb4 31. Nb3 Qd3
29. cxb5 Nc2 30. Nb3 Nxa1 31. Qxa1 Qc2 32. Qa2 Rxd2 33. Nxd2 Qxd2 34. b6 Bc5
EDIT - actually 34. Qc4 is probably better but we're getting crushed whatever move we play so
It'd be cool if people who've been looking at moves other than 29. cxb5 could post some lines. I've looked at quite a few other moves but could not bring myself to dig deep into the variations, it's hard for me to find the motivation to analyze a lost position, I would've already resigned a while ago if it was a one on one game.
