Calculation tips


you had rooks on the 2nd rank doubled... you never want to give that up because having rooks there means you will 100% have tactics to win material, checkmate, or at the very least a draw with repitition. Here the winning idea was a bit hard but keep both rooks in the 2nd and try to skewer his Rook h1, so something like 32. Rb2 (idea Rh1+ skewer), 33. Kg1 f4 (idea f3! protecting a Rook on g2 and it's gg)
Not so easy to see but strategically remember not to disconnect the Rooks pretty much ever, but you need some patience to find the tactics to make it a win.
If you do have doubled Rooks on the 2nd (or 7th if ur White) and you can't see a winning continuation - most likely that's because you need to look harder. it's ussually there... Don't tunnel vision on the king, look what material you can win with your dominance... and if it's really not there just repeat check check and make a draw...
