 click for larger view34 ... b4-b3! is a great example of Wang Yue's tactical prowess, finding a winning idea in an apparently simple drawish ending. <notyetagm: 33 ... b4-b3! is a tremendous example of <INTERFENCE> by Wang Yue.The point of this tactical shot is to <BLOCK> the diagonal a4-c2 at b3. Then White will be unable to meet the threat of piling on the <PINNED> White d7-bishop with 34 ... Nb7-d8 by <RUBBERBANDING> 35 Bd7-a4 since the line of the White a4-bishop does not reach the <UNDEFENDED> c2-rook due to the presence of either a Black pawn or a White pawn on b3. <INTERFERENCE> works along the lines of <"I <BLOCK> the line, you take it, YOU <BLOCK> the line">. With 33 ... b4-b3!, Black says "I <BLOCK> the line a4-c2 with my Black b3-pawn, if you take it with 34 a2xb3, then YOU <BLOCK> the line a4-c2 with YOUR b3-pawn." An ingenius tactical shot by Wang Yue, winning what looks like a fairly even endgame.> |
