TeamLeague T38: My 5th Round Game

After a painful 0.5-3.5 loss in round 5, our team is no longer in contention of reaching the playoffs. One round remains, but without any real significance. I am starting to plan on finding an even-matched match opponent when the league finishes.

Below is my 5th round game. In the diagram position below, I am clearly winning, but blundered away the game on a silly mistake on move 28.

24...Rg8+?

This is the wrong plan. [24...Red8 wins quickly.]

25.Kf3 h5 26.h4 Rgd8

With this move, Black gets back on the winning track.

27.g3 R8d3+ 28.Kg2 Rd1??

I simply didn't see that White's rook on a1 is defended by the bishop, and White can therefore simply eat the pawn. [28...Rc2 29.Bf6 Rd1-+ is one straightforward continuation that wins immediately.]

29.Rxe2= Rxa1?

Shaken after throwing away my winning advantage, I throw away the game.
