Win your won positions

Too bad you guys missed the point. There should be new positions...

8/6R1/2k2p2/5n2/1P6/3N3P/3K2P1/1r6 w - - 0 61
Try to win these one as white. White to move. It's from my last match.

Thanks, arz920!

I tried 3 times. The first two attempts were terrible. But I got lucky in the last one.

Nice, i don't get why Rf7 is better than Rg6 in the first move, you are going to take the pawn anyway.

I won on my first try but I feel my technique wasn't good
