Rook Bombs, Part 1

     A lot of famous and very strong tournaments have been played at Monte Carlo, 1901 through 1904 and 1967 through 1969. 
     The event in 1968 was organized by the French chess magazine Europe Echecs. In addition to the main event there were also Masters, Open and Junior events. For the 1968 main tournament a dozen strong GM's were invited, but British master and writer Harry Golombek groused that the inclusion of the two French players (Sylvain Zinzer and Rene Letzelter) was absurd and a waste of valuable places. 
     The Great Dane, Bent Larsen won his fifth successive first place; the others were: Havana (1967), Winnipeg (1967), Sousse Interzonal (1967) and Palma de Mallorca (1967). 
     Fischer, who had finished first at Monte Carlo the previous year, was a noticeable absence...because of his absurd demands tournament officials refused to even consider inviting him. Besides, the previous year when his trophy was presented to him by Prince Rainier and Princess Grace, being the execrable snot face that he was, Fischer refused to pose for a photograph with them. It's understandable why the tournament officials didn't want to deal with him. 
     The Masters tournament was won by Karoly Honfi ahead of Predrag Ostojic. The Open tournament was won by George Kuprejanov and the junior event was won by Georg Eppinger. 
     In the Major event, the star-studded field of eleven other Grandmasters were unable to stop Larsen.  From the very start he was never out of the lead although Botvinnik, Smyslov and Byrne kept the pace for a while.
 

     Larsen's play kept his opponents off guard. He sacrificed a Pawn for positional considerations against Gheorghiu, but against Botvinnik he played eccentric Nimzovichean strategy and got into trouble, but sharp tactics salvaged the draw.
     In round 12 he surprised everybody by making a practical decision and accepting a draw in a superior position against Smyslov. The draw assured him of a tie for first place even if he lost in the last round and Botvinnik won. 
     Botvinnik played steady, solid chess and might have achieved a tie for first had he continued his last round game against Damjanovic because he had good chances. Smyslov and Hort shared third place and along with Botvinnik were the only undefeated players. 
     Smyslov's play in the tournament was a bit casual and lacked sharpness. Hort played his usual tough chess while Byrne's play was erratic, sometimes he took early draws in positions that were slightly favorable (against Smyslov and Forintos), but at other times he sought out complex, difficult position where the outcome was going to be unclear. For example, against Bptvinnik, after 25 moves the position was so dangerous they decided to repeat moves. 
     The other American player, Pal Benko complained of fatigue resulting from his recent first place finish in the National Open that was held in Lake Tahoe, Nevada. Against Botvinnik he had a positional advantage then made an unsound piece sacrifice and lost. 
     Romanian star Florin Gheorghiu threw away three or four games through carelessness play and shoddy technique. The powerful Hungarian GM Lajos Portisch player had an upcoming match against Larsen and seemed distracted; he was the only GM to be upset by the French players when he losy to Letzelter. 
     In the following game Botvinnik's opening strategy was based on his fianchettoed Bishop and when Portisch made a minor mistake, his Q-side came under pressure. Seeking to relieve the pressure he undertook to regroup his pieces and then WHAMO! Botvinnik launched a K-side attack that involved sacrificing one Rook and then offering up the other one. 
 
A game that I liked (Komodo 14)

This one is designed to guard against the possibility of white playing Qb5 (a consequence of black's 9th move!) which gives him threats against the P on b7 and, also, tactical threats against black's e-Pawn. Portisch will also move the N and play ...c6. But, before he can do that, he has to defend the e-Pawn and this and the B retreat next move accomplish that purpose.} 14. Rc2 Bf8 15. Rac1 {A crucial position! White has a clear advantage owing to his pressure on the c-file.
