MTK 3.5-UKSE 2.5

I contributed a draw on the black side of a Nimzo-Indian

This completes a hectic week(end) with a tournament and two team matches

Now I need a rest

Getting ready

Nagy,G-Yip

Nimzo-Indian 4.a3

I started with a promising position but kept missing the correct plan(..c4). The in the ending I made a horrible number of mistakes

After 49.Bc7(Diagram)

Black has just won the g3-pawn but now the a5-pawn is attacked and there is also the Nxg4 threat to deal with

What do you recommend for Black?
