[Event "Warsaw"] [Site "?"] [Round "0"] [White "Marshall"] [Black "Stoltz"] [Result "0-1"] [FEN "2r2rk1/pp1q1ppp/4p3/2Pp4/3Q4/P1R1PP2/1P3P1P/5RK1 b - - 0 1"] {With a suprising pawn sacrifice, Black prepares a Rook foray on his third rank Positionally, White's situation is not at all bad. He has the Queenside pawn majority, and an open g-file which may have great future possibilities. For the moment the one feature which overshadows all others is the weakening of White's King position. This is the background of the following combination} 1... e5 $3 2. Qxe5 Rc6 3. e4 (3. Kh1 Qh3 4. Rg1 Qxf3+) 3... d4 $1 {This forces the White Rook along the third rank to an undefended square, and so eliminates the defence by Pf4} (3... Qh3 4. f4 $1) 4. Rd3 Qh3 {now ... Pf4 isn't possible} 5. Rxd4 Rg6+ 0-1
