About the Semi-Slav Defense
Black combines ...c6 and ...e6 against the Queen's Gambit, making a solid triangle around d5. Some lines, like the Meran and Botvinnik, are very sharp.
Black can take on c4 with ...dxc4 and hold the pawn with ...b5.
The freeing breaks are ...c5 and ...e5.
The c8 bishop often goes to b7 after ...b5 or ...b6.
